Captopril: A potent and specific inhibitor of PEPTIDYL-DIPEPTIDASE A. It blocks the conversion of ANGIOTENSIN I to ANGIOTENSIN II, a vasoconstrictor and important regulator of arterial blood pressure. Captopril acts to suppress the RENIN-ANGIOTENSIN SYSTEM and inhibits pressure responses to exogenous angiotensin.Angiotensin-Converting Enzyme Inhibitors: A class of drugs whose main indications are the treatment of hypertension and heart failure. They exert their hemodynamic effect mainly by inhibiting the renin-angiotensin system. They also modulate sympathetic nervous system activity and increase prostaglandin synthesis. They cause mainly vasodilation and mild natriuresis without affecting heart rate and contractility.Proline: A non-essential amino acid that is synthesized from GLUTAMIC ACID. It is an essential component of COLLAGEN and is important for proper functioning of joints and tendons.Radioisotope Renography: Graphic tracing over a time period of radioactivity measured externally over the kidneys following intravenous injection of a radionuclide which is taken up and excreted by the kidneys.Renin: A highly specific (Leu-Leu) endopeptidase that generates ANGIOTENSIN I from its precursor ANGIOTENSINOGEN, leading to a cascade of reactions which elevate BLOOD PRESSURE and increase sodium retention by the kidney in the RENIN-ANGIOTENSIN SYSTEM. The enzyme was formerly listed as EC 3.4.99.19.Blood Pressure: PRESSURE of the BLOOD on the ARTERIES and other BLOOD VESSELS.Hypertension, Renovascular: Hypertension due to RENAL ARTERY OBSTRUCTION or compression.Renin-Angiotensin System: A BLOOD PRESSURE regulating system of interacting components that include RENIN; ANGIOTENSINOGEN; ANGIOTENSIN CONVERTING ENZYME; ANGIOTENSIN I; ANGIOTENSIN II; and angiotensinase. Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming ANGIOTENSIN I. Angiotensin-converting enzyme, contained in the lung, acts on angiotensin I in the plasma converting it to ANGIOTENSIN II, an extremely powerful vasoconstrictor. Angiotensin II causes contraction of the arteriolar and renal VASCULAR SMOOTH MUSCLE, leading to retention of salt and water in the KIDNEY and increased arterial blood pressure. In addition, angiotensin II stimulates the release of ALDOSTERONE from the ADRENAL CORTEX, which in turn also increases salt and water retention in the kidney. Angiotensin-converting enzyme also breaks down BRADYKININ, a powerful vasodilator and component of the KALLIKREIN-KININ SYSTEM.Angiotensin I: A decapeptide that is cleaved from precursor angiotensinogen by RENIN. Angiotensin I has limited biological activity. It is converted to angiotensin II, a potent vasoconstrictor, after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME.Technetium Tc 99m Mertiatide: A technetium diagnostic aid used in renal function determination.Angiotensin II: An octapeptide that is a potent but labile vasoconstrictor. It is produced from angiotensin I after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME. The amino acid in position 5 varies in different species. To block VASOCONSTRICTION and HYPERTENSION effect of angiotensin II, patients are often treated with ACE INHIBITORS or with ANGIOTENSIN II TYPE 1 RECEPTOR BLOCKERS.Peptidyl-Dipeptidase A: A peptidyl-dipeptidase that catalyzes the release of a C-terminal dipeptide, -Xaa-*-Xbb-Xcc, when neither Xaa nor Xbb is Pro. It is a Cl(-)-dependent, zinc glycoprotein that is generally membrane-bound and active at neutral pH. It may also have endopeptidase activity on some substrates. (From Enzyme Nomenclature, 1992) EC 3.4.15.1.Technetium Tc 99m Pentetate: A technetium imaging agent used in renal scintigraphy, computed tomography, lung ventilation imaging, gastrointestinal scintigraphy, and many other procedures which employ radionuclide imaging agents.Hydrochlorothiazide: A thiazide diuretic often considered the prototypical member of this class. It reduces the reabsorption of electrolytes from the renal tubules. This results in increased excretion of water and electrolytes, including sodium, potassium, chloride, and magnesium. It is used in the treatment of several disorders including edema, hypertension, diabetes insipidus, and hypoparathyroidism.Iodohippuric Acid: An iodine-containing compound used in pyelography as a radiopaque medium. If labeled with radioiodine, it can be used for studies of renal function.Hypertension: Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.Saralasin: An octapeptide analog of angiotensin II (bovine) with amino acids 1 and 8 replaced with sarcosine and alanine, respectively. It is a highly specific competitive inhibitor of angiotensin II that is used in the diagnosis of HYPERTENSION.Enalapril: An angiotensin-converting enzyme inhibitor that is used to treat HYPERTENSION and HEART FAILURE.Isosorbide: 1,4:3,6-Dianhydro D-glucitol. Chemically inert osmotic diuretic used mainly to treat hydrocephalus; also used in glaucoma.Antihypertensive Agents: Drugs used in the treatment of acute or chronic vascular HYPERTENSION regardless of pharmacological mechanism. Among the antihypertensive agents are DIURETICS; (especially DIURETICS, THIAZIDE); ADRENERGIC BETA-ANTAGONISTS; ADRENERGIC ALPHA-ANTAGONISTS; ANGIOTENSIN-CONVERTING ENZYME INHIBITORS; CALCIUM CHANNEL BLOCKERS; GANGLIONIC BLOCKERS; and VASODILATOR AGENTS.Kinins: A generic term used to describe a group of polypeptides with related chemical structures and pharmacological properties that are widely distributed in nature. These peptides are AUTACOIDS that act locally to produce pain, vasodilatation, increased vascular permeability, and the synthesis of prostaglandins. Thus, they comprise a subset of the large number of mediators that contribute to the inflammatory response. (From Goodman and Gilman's The Pharmacologic Basis of Therapeutics, 8th ed, p588)Bradykinin: A nonapeptide messenger that is enzymatically produced from KALLIDIN in the blood where it is a potent but short-lived agent of arteriolar dilation and increased capillary permeability. Bradykinin is also released from MAST CELLS during asthma attacks, from gut walls as a gastrointestinal vasodilator, from damaged tissues as a pain signal, and may be a neurotransmitter.Rats, Inbred SHR: A strain of Rattus norvegicus with elevated blood pressure used as a model for studying hypertension and stroke.Hydralazine: A direct-acting vasodilator that is used as an antihypertensive agent.Renal Artery Obstruction: Narrowing or occlusion of the RENAL ARTERY or arteries. It is due usually to ATHEROSCLEROSIS; FIBROMUSCULAR DYSPLASIA; THROMBOSIS; EMBOLISM, or external pressure. The reduced renal perfusion can lead to renovascular hypertension (HYPERTENSION, RENOVASCULAR).Losartan: An antagonist of ANGIOTENSIN TYPE 1 RECEPTOR with antihypertensive activity due to the reduced pressor effect of ANGIOTENSIN II.Isosorbide Dinitrate: A vasodilator used in the treatment of ANGINA PECTORIS. Its actions are similar to NITROGLYCERIN but with a slower onset of action.Receptors, Bradykinin: Cell surface receptors that bind BRADYKININ and related KININS with high affinity and trigger intracellular changes which influence the behavior of cells. The identified receptor types (B-1 and B-2, or BK-1 and BK-2) recognize endogenous KALLIDIN; t-kinins; and certain bradykinin fragments as well as bradykinin itself.Aldosterone: A hormone secreted by the ADRENAL CORTEX that regulates electrolyte and water balance by increasing the renal retention of sodium and the excretion of potassium.Hemodynamics: The movement and the forces involved in the movement of the blood through the CARDIOVASCULAR SYSTEM.TetrazolesAngiotensin Receptor Antagonists: Agents that antagonize ANGIOTENSIN RECEPTORS. Many drugs in this class specifically target the ANGIOTENSIN TYPE 1 RECEPTOR.Enalaprilat: The active metabolite of ENALAPRIL and a potent intravenously administered angiotensin-converting enzyme inhibitor. It is an effective agent for the treatment of essential hypertension and has beneficial hemodynamic effects in heart failure. The drug produces renal vasodilation with an increase in sodium excretion.Renal Circulation: The circulation of the BLOOD through the vessels of the KIDNEY.Kidney: Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.Nobel PrizeEncyclopedias as Topic: Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject.

It stabilizes MICROTUBULES in their polymerized form leading to cell death.Heart Failure: A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.History, 19th Century: Time period from 1801 through 1900 of the common era.History, 20th Century: Time period from 1901 through 2000 of the common era.Sodium Chloride Symporter Inhibitors: Agents that inhibit SODIUM CHLORIDE SYMPORTERS.

The reaction may include rapidly progressing URTICARIA, respiratory distress, vascular collapse, systemic SHOCK, and death.Universal Precautions: Prudent standard preventive measures to be taken by professional and other health personnel in contact with persons afflicted with a communicable disease, to avoid contracting the disease by contagion or infection. Precautions are especially applicable in the diagnosis and care of AIDS patients.Postural Orthostatic Tachycardia Syndrome: A syndrome of ORTHOSTATIC INTOLERANCE combined with excessive upright TACHYCARDIA, and usually without associated ORTHOSTATIC HYPOTENSION. All variants have in common an excessively reduced venous return to the heart (central HYPOVOLEMIA) while upright.Drug Interactions: The action of a drug that may affect the activity, metabolism, or toxicity of another drug.Fatigue Syndrome, Chronic: A syndrome characterized by persistent or recurrent fatigue, diffuse musculoskeletal pain, sleep disturbances, and subjective cognitive impairment of 6 months duration or longer. Symptoms are not caused by ongoing exertion; are not relieved by rest; and result in a substantial reduction of previous levels of occupational, educational, social, or personal activities. Minor alterations of immune, neuroendocrine, and autonomic function may be associated with this syndrome. There is also considerable overlap between this condition and FIBROMYALGIA. (From Semin Neurol 1998;18(2):237-42; Ann Intern Med 1994 Dec 15;121(12): 953-9)Pleurodynia, Epidemic: An acute, febrile, infectious disease generally occurring in epidemics.

Although most individuals have symptoms of both inattention and hyperactivity-impulsivity, one or the other pattern may be predominant. The disorder is more frequent in males than females. Onset is in childhood. Symptoms often attenuate during late adolescence although a minority experience the full complement of symptoms into mid-adulthood. (From DSM-V)Amyotrophic Lateral Sclerosis: A degenerative disorder affecting upper MOTOR NEURONS in the brain and lower motor neurons in the brain stem and SPINAL CORD.

Restriction of placental and fetal growth in sheep alters fetal blood pressure responses to angiotensin II and captopril. (1/1305)

1. We have measured arterial blood pressure between 115 and 145 days gestation in normally grown fetal sheep (control group; n = 16) and in fetal sheep in which growth was restricted by experimental restriction of placental growth and development (PR group; n = 13). There was no significant difference in the mean gestational arterial blood pressure between the PR (42.7 +/- 2.6 mmHg) and control groups (37.7 +/- 2.3 mmHg). Mean arterial blood pressure and arterial PO2 were significantly correlated in control animals (r = 0.53, P < 0.05, n = 16), but not in the PR group. 2. There were no changes in mean arterial blood pressure in either the PR or control groups in response to captopril (7.5 microg captopril min-1; PR group n = 7, control group n = 6) between 115 and 125 days gestation. After 135 days gestation, there was a significant decrease (P < 0.05) in the fetal arterial blood pressure in the PR group but not in the control group during the captopril infusion (15 microg captopril min-1; PR group n = 7, control group n = 6). 3. There was a significant effect (F = 14.75; P < 0.001) of increasing doses of angiotensin II on fetal diastolic blood pressure in the PR and control groups. The effects of angiotensin II were different (F = 8.67; P < 0.05) in the PR and control groups at both gestational age ranges. 4. These data indicate that arterial blood pressure may be maintained by different mechanisms in growth restricted fetuses and normally grown counterparts and suggests a role for the fetal renin-angiotensin system in the maintenance of blood pressure in growth restricted fetuses.  (+info)

Inhibition of beta-myosin heavy chain gene expression in pressure overload rat heart by losartan and captopril. (2/1305)

AIM: To study the effects of losartan and captopril on beta-myosin heavy chain (MHC), and alpha-MHC gene expression. METHODS: Pressure overload was produced by abdominal aortic coarctation (AAC) in rats. alpha- and beta-MHC mRNA were measured by Northern blot. RESULTS: In left ventricular myocardium of sham-operated rats, the alpha-MHC mRNA predominated, while the beta-MHC mRNA was only detectable. In response AAC, there was a 70-fold increase in the beta-MHC mRNA (P < 0.01), while alpha-MHC mRNA reduced to 26% (P < 0.01). Losartan (3 mg.kg-1.d-1, i.g. for 11 d) to AAC rats caused inhibitions of beta-MHC by 96% and alpha-MHC by 86% gene expression without lowering blood pressure. A reduction in beta-MHC mRNA was also seen in captopril-treated rats (30 mg.kg-1.d-1, i.g. for 11 d), but the inhibitory effect of captopril on alpha-MHC mRNA was less than that of losartan (44% vs 86%, P < 0.05). CONCLUSIONS: The shift of MHC isoform induced by pressure overload is due to up-regulation of beta-MHC and down-regulation of alpha-MHC gene expression. Inhibition of beta-MHC gene expression by losartan is achieved primarily by direct blockade of angiotensin II type I receptors in the myocardium, independent on hemodynamics.  (+info)

Effects of captopril and enalaprilat on intracellular Ca2+, Na+ contents and pH in hypoxic and reoxygenated cardiomyocytes. (3/1305)

AIM: To study the mechanisms of captopril (Cap) and enalaprilat (Ena) protective effects on hypoxic and reoxygenated cardiac myocytes. METHODS: Using fluorescent probes Fura 2-AM, BCECF/AM, SBFI/AM combined with computer image processing techniques to measure intracellular ion concentrations. RESULTS: [Ca2+]i (165 +/- 8 nmol.L-1) and [Na+]i (9.2 +/- 0.8 mmol.L-1) were higher but [pH]i (6.7 +/- 0.3) was lower in hypoxic and reoxygenated myocytes (196 +/- 14 nmol.L-1, 9.3 +/- 1.3 mmol.L-1, 6.61 +/- 0.19, respectively) than in normal ones. Cap and Ena reduced [Ca2+]i (149 +/- 11 and 152 +/- 10 nmol.L-1 respectively) and intracellular acidosis (7.11 +/- 0.22 and 7.2 +/- 0.4, respectively) during hypoxia. Cap also decreased [Na+]i in hypoxic myocytes (8.1 +/- 0.9 mmol.L-1). During reoxygenation, Cap decreased [Ca2+]i and [Na+]i but Ena had no significant effect on them. Cap or Ena had no additive effect when combined with verapamil (Ver). CONCLUSION: Cap and Ena protected hypoxic and reoxygenated cardiomyocytes, but the mechanisms were not the same.  (+info)

Neurogenic plasma leakage in mouse airways. (4/1305)

1. This study sought to determine whether neurogenic inflammation occurs in the airways by examining the effects of capsaicin or substance P on microvascular plasma leakage in the trachea and lungs of male pathogen-free C57BL/6 mice. 2. Single bolus intravenous injections of capsaicin (0.5 and 1 micromol kg(-1), i.v.) or substance P (1, 10 and 37 nmol kg(-10, i.v.) failed to induce significant leakage in the trachea, assessed as extravasation of Evans blue dye, but did induce leakage in the urinary bladder and skin. 3. Pretreatment with captopril (2.5 mg kg(-1), i.v.), a selective inhibitor of angiotensin converting enzyme (ACE), either alone or in combination with phosphoramidon (2.5 mg kg(-1), i.v.), a selective inhibitor of neutral endopeptidase (NEP), increased baseline leakage of Evans blue in the absence of any exogenous inflammatory mediator. The increase was reversed by the bradykinin B2 receptor antagonist Hoe 140 (0.1 mg kg(-1), i.v.). 4. After pretreatment with phosphoramidon and captopril, capsaicin increased the Evans blue leakage above the baseline in the trachea, but not in the lung. This increase was reversed by the tachykinin (NK1) receptor antagonist SR 140333 (0.7 mg kg(-1), i.v.), but not by the NK2 receptor antagonist SR 48968 (1 mg kg(-1), i.v.). 5. Experiments using Monastral blue pigment as a tracer localized the leakage to postcapillary venules in the trachea and intrapulmonary bronchi, although the labelled vessels were less numerous in mice than in comparably treated rats. Blood vessels of the pulmonary circulation were not labelled. 6. We conclude that neurogenic inflammation can occur in airways of pathogen-free mice, but only after the inhibition of enzymes that normally degrade inflammatory peptides. Neurogenic inflammation does not involve the pulmonary microvasculature.  (+info)

Quality of life in chronic heart failure: cilazapril and captopril versus placebo. Cilazapril-Captopril Multicentre Group. (5/1305)

OBJECTIVE: To measure quality of life (QOL) in patients with mild to moderate heart failure treated with angiotensin converting enzyme (ACE) inhibitors cilazapril or captopril. DESIGN: Randomised, double blind, placebo controlled, parallel groups trial. SUBJECTS: 367 patients with New York Heart Association (NYHA) heart failure class II (62%), III (36%) or IV (1%). METHODS: Patients were randomised to receive cilazapril 1 mg daily (n = 191) or captopril 25 mg three times daily (n = 90) for 24 weeks, or placebo for 12 weeks followed by cilazapril 1 mg daily for a further 12 weeks (n = 86). If patients had not responded after four weeks cilazapril was increased to 2.5 mg daily and captopril to 50 mg three times daily. QOL was assessed at baseline, 12, and 24 weeks using the sickness impact profile (SIP), the profile of mood states (POMS), the Mahler index of dyspnoea-fatigue, and a health status index (HSI). RESULTS: The physical dimension of the SIP averaged 7 units at baseline and improved after 12 weeks by 2.24 units in the cilazapril group, 2.38 units in the captopril group, and 1.51 units in the placebo group. The difference between drug and placebo was therefore 0.73 units (95% CI -0.86 to 2.32) for cilazapril, and 0.87 units (95% CI -0.96 to 2.70) for captopril, with small non-significant effect sizes (a statistical method for estimating the importance of a treatment related change) of 0.12 and 0.14. Similar results were observed for the total POMS and HSI scores. Although QOL improved more on the ACE inhibitors than on placebo, the effect sizes were not significant (< or = 0.26). CONCLUSIONS: Improvements in QOL in mild to moderate heart failure were small when treated with cilazapril or captopril compared with placebo.  (+info)

Renal and metabolic clearance of N-acetyl-seryl-aspartyl-lysyl-proline (AcSDKP) during angiotensin-converting enzyme inhibition in humans. (6/1305)

We investigated the contributions of angiotensin-converting enzyme (ACE) and glomerular filtration to creating the new metabolic balance of the hemoregulatory peptide N-acetyl-seryl-aspartyl-lysyl-proline (AcSDKP) that occurs during acute and chronic ACE inhibition in healthy subjects. We also studied the effect of chronic renal failure on the plasma concentration of AcSDKP during long-term ACE inhibitor (ACEI) treatment or in its absence. In healthy subjects, a single oral dose of 50 mg captopril (n=32) and a 7-day administration of 50 mg captopril BID (n=10) resulted in a respective 42-fold (range, 18- to 265-fold) and 34-fold (range, 24-fold to 45-fold) increase in the ratio of urinary AcSDKP to creatinine accompanied by a 4-fold (range, 2- to 6.8-fold) and 4.8-fold (range, 2.6- to 11.8-fold) increase in plasma AcSDKP levels. Changes in plasma AcSDKP and in vitro ACE activity over time showed an intermittent reactivation of ACE between each captopril dose. In subjects with chronic renal failure (creatinine clearance<60 mL/min per 1.73 m2), plasma AcSDKP levels were 22 times higher (95% confidence interval, 15 to 33) in the ACEI group (n=35) than the control group (n=23); in subjects with normal renal function, they were only 4.1 times higher (95% confidence interval, 3.2 to 5.3) in the ACEI group (n=19) than the non-ACEI group (n=21). Renal failure itself led to a slight increase in plasma AcSDKP concentration. In conclusion, intermittent reactivation of ACE between doses of an ACEI is the major mechanism accounting for the lack of major AcSDKP accumulation during chronic ACE inhibition in subjects with normal renal function.  (+info)

Hypotensive response to captopril: a potential pitfall of scintigraphic assessment for renal artery stenosis. (7/1305)

A characteristic pattern seen on captopril renography is described that is due to systemic hypotensive response. Most patients with these findings on captopril renography do not receive renal artery angiograms in our clinic because it is usually recognized. However, this pattern has received little attention in the medical literature and may be misinterpreted as being due to physiologically significant renal artery hypertension. METHODS: Over the last 3 y, renal artery angiograms were performed on three patients with systemic hypotensive response pattern on captopril renography. This allowed a unique opportunity to correlate the results of the captopril renogram with the renal artery angiograms in this patient population. Captopril renography was performed with a glomerular filtration agent, diethylenetriamine pentaacetic acid (DTPA), and a tubular agent, o-iodohipurate (OIH). RESULTS: Renal artery angiograms showed no evidence of renal artery stenosis in three patients with systemic hypotensive response pattern on captopril renography. Systemic hypotension on captopril renograms results in preserved uptake of both DTPA and OIH and hyperconcentration in the cortex and collecting system. CONCLUSION: The systemic hypotensive response pattern seen on captopril renography is a distinctive pattern that does not represent physiologically significant renal artery stenosis.  (+info)

Value of captopril renal scintigraphy in hypertensive patients with renal failure. (8/1305)

The aims of this study were to show the value of captopril renal scintigraphy for detecting a renovascular cause in hypertensive patients with renal failure and to assess the ability to predict the beneficial effect of revascularization on renal function. METHODS: Thirty-eight patients with renal failure (mean glomerular filtration rate = 35 mL/min) underwent renal scintigraphy after injection of 99mTc-mercaptoacetyltriglycine. Baseline scintigraphy was performed, and the test was repeated 24 h later after oral administration of 50 mg captopril given 60 min before the test. RESULTS: In 5 of 6 patients with a renovascular cause for renal failure, and 2 of 3 patients with a probable arterial pathology, scintigraphy had a high probability. The result was indeterminate in the other 2 patients. In 5 of 11 patients with negative arteriography and 14 of 18 patients with probable absence of renovascular pathology, we found a low probability of functional renal artery stenosis. Six revascularization procedures were performed and were predictive of a beneficial effect in 5 patients. Time of peak activity was an effective predictor in each case. CONCLUSION: In hypertensive patients with renal failure, captopril renal scintigraphy can detect hemodynamic dysfunction downstream from a renal artery stenosis and can predict the beneficial effect of revascularization in some cases.  (+info)

Objectives. This study attempted to evaluate whether neurohumoral activation at the time of hospital discharge in postinfarction patients helps to predict long-term prognosis and whether long-term therapy with the angiotensin-converting enzyme inhibitor captopril modifies this relation.. Background. Neurohumoral activation persists at the time of hospital discharge in a large number of postinfarction patients. The Survival and Ventricular Enlargement (SAVE) study demonstrated that the angiotensin-converting enzyme inhibitor captopril improves survival and decreases the development of severe heart failure in patients with left ventricular dysfunction (left ventricular ejection fraction ≤40%) but no overt postinfarction heart failure.. Methods. In 534 patients in the SAVE study, plasma neurohormone levels were measured a mean of 12 days after infarction. Patients were then randomized to receive captopril or placebo and were followed up for a mean (±SD) of 38 ± 6 months (range 24 to 55). The ...
The most remarkable observations of the study were related to the comparative effects of poststroke losartan versus captopril treatment. After 31 days of losartan treatment, the MCAs of SHRsp regained the ability to constrict in response to pressure and NOS inhibition. Such treatment also restored vasodilator function in response to bradykinin, established prestroke oscillatory characteristics, and enhanced vasodilation in response to A23187. Captopril treatment did not duplicate these effects. A short (7 day) duration of captopril treatment allowed the MCAs of SHRsp to temporarily regain these functions; however, after 18 days of treatment, these cerebrovascular functions deteriorated. After 31 to 37 days of captopril treatment, the characteristics of PDC, constriction in response to NOS inhibition, and bradykinin vasodilation were not different from those observed in the MCAs of SHRsp at the time of stroke. The differences in the action of losartan versus captopril cannot be explained on the ...

N2 - Exercise capacity in patients with left heart failure is closely related to the performance of the right ventricle and the pulmonary circulation. To determine the significance of changes in pulmonary resistance during longterm vasodilator therapy, hemodynamic studies were performed before and after 1 to 3 months of treatment with captopril in 75 patients with severe chronic left heart failure. Patients were grouped according to the relative changes in pulmonary and systemic resistances during long-term therapy: patients in Group I (n = 24) showed greater decreases in pulmonary arteriolar resistance (PAR) than in systemic vascular resistance (SVR) (% Δ PAR/% Δ SVR,1.0), whereas patients in Group II showed predominant systemic ...

Nine patients with uncomplicated essential hypertension received, according to a randomized sequence, captopril (25 mg three times daily), nifedipine (10 mg three times daily), and both drugs for 1 week, with each treatment period separated by a 1-week interval during which a placebo was given. Captopril significantly reduced blood pressure and plasma aldosterone, increased plasma renin activity (PRA), and did not change heart rate. Nifedipine exerted a similar effect on blood pressure and PRA, but it increased heart rate and did not change aldosterone. Captopril plus nifedipine further reduced blood pressure and increased PRA, did not change heart rate, and reduced aldosterone to values similar to those after captopril alone. The hypotensive effect of captopril was highly predictable by basal PRA values, and that of nifedipine by age, while PRA increments induced by captopril were unrelated to those induced by nifedipine. These data indicate that: 1) captopril and nifedipine exert an additive ...
TY - JOUR. T1 - The angiotensin converting enzyme inhibitor captopril protects nigrostriatal dopamine neurons in animal models of parkinsonism. AU - Sonsalla, Patricia K.. AU - Coleman, Christal. AU - Wong, Lai Yoong. AU - Harris, Suzan L.. AU - Richardson, Jason R.. AU - Gadad, Bharathi S.. AU - Li, Wenhao. AU - German, Dwight C.. PY - 2013/12. Y1 - 2013/12. N2 - Parkinsons disease (PD) is a progressive neurodegenerative disorder characterized by a prominent loss of nigrostriatal dopamine (DA) neurons with an accompanying neuroinflammation. The peptide angiotensin II (AngII) plays a role in oxidative-stress induced disorders and is thought to mediate its detrimental actions via activation of AngII AT1 receptors. The brain renin-angiotensin system is implicated in neurodegenerative disorders including PD. Blockade of the angiotensin converting enzyme or AT1 receptors provides protection in acute animal models of parkinsonism. We demonstrate here that treatment of mice with the angiotensin ...
The captopril challenge test (CCT) is a non-invasive medical test that measures the change in renin plasma-levels in response to administration of captopril, an angiotensin converting enzyme inhibitor. It is used to assist in the diagnosis of renal artery stenosis. It is not generally considered a useful test for children, and more suitable options are available for adult cases. Plasma concentration of renin is measured prior to and following the administration of captopril. The CCT is considered positive if the renin levels increase substantially or the baseline renin level is abnormally high. An abnormal captopril test is indicative of the presence of renovascular disease. CCT in adults is known to have high sensitivity, but a low specificity. Subtraction angiography is considered a more suitable test for renal artery stenosis in adults. Contrast with captopril suppression test used to diagnose primary aldosteronism Gauthier B, Trachtman H, Frank R, Pillari G. Inadequacy of captopril challenge ...

Numerous studies have shown favorable effects on parameters of LV remodeling for drugs that improve clinical outcomes in patients with decreased LVEF and LV dilation, notably angiotensin-converting enzyme inhibitors, beta-blockers, and angiotensin receptor blockers (14,15,18,57,63-69). Conversely, agents with neutral or adverse effects on remodeling, relative to a comparator, have often been found to be associated with neutral or adverse effects on clinical outcomes. Examples include omapatrilat (70,71) and ibopamine (72,73). In a head-to-head comparison of the angiotensin-converting enzyme inhibitor captopril, 150 mg daily, with the angiotensin receptor blocker losartan, 50 mg daily, we found a trend favoring captopril in the 1-year change in LV volumes (18), an effect that presaged the mortality findings in ELITE (Early Versus Late Intervention Trial With Estradiol) II (74). Yu et al. (75) showed that a decrease in LV ESV of ≥10% after cardiac resynchronization therapy predicted decreased ...
Pulmonary vascular remodeling is one of the typical responses to chronic alveolar hypoxia in the rat model of pulmonary hypertension (PH). Neither the etiology nor the structural and functional consequences of this remodeling are well understood. It is known that chronic treatment with ACE inhibitors results in a reduction of lung perfusion pressures and vascular changes in hypoxic PH, but the effect of treatment with ACE inhibitors on arterial tree morphology and mechanical properties of the artery walls in the intact lung have not been examined. In addition to using standard hemodynamic analysis, we approach this problem with x-ray micro-CT imaging and measure the distensibility of pulmonary arteries (approximate range of 50 - 2000 um diameter) in rat lungs. We examine consequences of chronic hypoxic exposure (10% O2) with and without Captopril treatment in FH, SD and BN rats. The FH rat strain is known to possess a genetic susceptibility to PH whereas the BN strain is resistant to PH. An example of
Acute reversible renal failure may complicate therapy with Captopril in patients with bilateral renal-artery stenoses or renal-artery stenosis in a solitary kidney (1-6). The concomitant use of diuretic agents in many of the reported cases of captopril-induced renal insufficiency has led to speculation that diuretic therapy or sodium depletion may contribute to the decrement in glomerular filtration rate mediated by angiotensin-converting enzyme inhibitors in the presence of a fixed reduction in renal perfusion pressure (1, 6). To determine the influence of sodium balance on captopril-induced renal insufficiency, the renal hemodynamic effects of Captopril were studied prospectively in a patient with ...
The interaction of the renin-angiotensin system and the sympathetic nervous system in patients with congestive heart failure is not well understood. We tested the hypothesis that angiotensin-converting enzyme inhibitors can resensitize the beta-adrenergic receptor system. Guinea pigs were given captopril, isoproterenol, or both for 2 weeks. At death, cardiac sarcolemmal and light vesicle fractions and intact mononuclear leukocytes were prepared. Captopril treatment led to an up-regulation of cardiac beta 1- but not mononuclear leukocyte beta 2-adrenergic receptors and an increase in isoproterenol-stimulated adenylate cyclase activity in the heart. Animals treated with isoproterenol developed cardiac hypertrophy, had increased plasma norepinephrine levels, and had a decreased number and responsiveness of both cardiac and mononuclear leukocyte beta-adrenergic receptors. Concomitant treatment with captopril attenuated alterations of heart weight, plasma norepinephrine levels, and cardiac ...
Increased generation of reactive oxygen species (ROS) is a significant pathological feature in the brains of patients with Alzheimers disease (AD). Experimental evidence indicates that inhibition of brain ROS could be beneficial in slowing the neurodegenerative process triggered by amyloid-beta (Abeta) aggregates. The angiotensin II AT1 receptor is a significant source of brain ROS, and AD patients have an increased brain angiotensin-converting enzyme (ACE) level, which could account for an excessive angiotensin-dependent AT1-induced ROS generation. Therefore, we analyzed the impact of ACE inhibition on signs of neurodegeneration of aged Tg2576 mice as a transgenic animal model of AD. Whole genome microarray gene expression profiling and biochemical analyses demonstrated that the centrally active ACE inhibitor captopril normalized the excessive hippocampal ACE activity of AD mice. Concomitantly, the development of signs of neurodegeneration was retarded by six months of captopril treatment. The ...

BACKGROUND: Although oral administration of captopril, an angiotensin-converting enzyme inhibitor, is effective for the treatment of congestive heart failure (CHF), the effect of its intravenous (iv) administration is not well known. METHODS AND RESULTS: Ten patients (age range 48-72 years), with CHF belonging to the second and third NYHA class, were given an iv bolus of 25 mg of captopril. Before and 30 minutes after the infusion of captopril, a number of parameters of the left ventricular function were evaluated by echocardiography IREX 3 M-B Mode. Eight patients showed a significant improvement of left ventricular performance indices. In fact, the ejection fraction (13.8%, p , 0.05), the cardiac output (24%, p , 0.001), the circumferential shortness fraction (29.9%, p , 0.05), and the fraction shortening (16.0%, p , 0.005) increased significantly, whereas the end-systolic diameter (21%, p , 0.001), the endsystolic stress (23.8%, p , 0.01) and the left ventricle ejection time (4.8%, p , 0.05) ...
It is important to consider secondary causes of hypertension (eg, renovascular hypertension) that may have precipitated the crisis. A single dose captopril (Capoten) challenge test may be performed, particularly in patients who have not received previous medical therapy for hypertension. Baseline plasma renin activity is measured and the patient is given 25 to 50 mg of captopril; measurement is repeated 60 minutes later. Test sensitivity is excellent but specificity is poor. Thus, further testing (eg, renal arterial Doppler ultrasonography, renal magnetic resonance angiography, contrast angiography) may be necessary to confirm diagnosis. Before initiating therapy, metanephrine levels can be measured by performing spot urine test to rule out the presence of pheochromocytoma. Plasma aldosterone and renin levels should be tested to rule out primary hyperaldosteronism in patients with significant hypokalemia who are not taking diuretics at the time of presentation..

Captopril can be used alone in treating high blood pressure. Its blood pressure lowering effect can be further enhanced by the addition of a diuretic (water pill) medication. Capozide is an example of a medication that combines the effect of Captopril with a diuretic (water pill). By reducing resistance in the arteries, Captopril can be useful in the treatment of congestive heart failure. In treating heart failure, Captopril usually supplements conventional treatment, including a diuretic and digoxin (Lanoxin). After a heart attack, Captopril has been found to be effective in improving functioning of the damaged heart. It is also used to treat kidney disease associated with diabetes ...

Several trials have shown that converting enzyme inhibitors (CEI) reduce mortality in patients with heart failure. More recent studies have tested CEIs after acute MI. In the CONSENSUS II trial (1), enalapril was begun intravenously and a nonsignificant higher mortality rate was found, whereas investigators of the more recent GISSI-3 (2) found that oral lisinopril significantly reduced 6-week mortality. Now, the ISIS-4 investigators have also found a significant lower mortality rate at 5 weeks with the use of oral captopril. Hypotension was more common among patients treated with CEIs in each trial. The findings suggest that CEIs begun soon after onset of MI reduce short-term mortality, although care is necessary in starting therapy, especially in patients with systolic blood pressure , 100 mm Hg. Patients at higher risk may have greater mortality reductions from CEI therapy because of their lower ejection fractions, especially patients with either anterior MI or previous MI. The ISIS-4 ...

Administration of captopril results in a reduction of peripheral arterial resistance in hypertensive patients with either no change, or an increase in cardiac output. There is an increase in renal blood flow following administration of captopril and glomerular filtration rate is usually unchanged.. Reductions of blood pressure are usually maximal 60 to 90 minutes after oral administration of an individual dose of captopril. The duration of effect is dose related. The reduction in blood pressure may be progressive, so to achieve maximal therapeutic effects, several weeks of therapy may be required. The blood pressure lowering effects of captopril and thiazide-type diuretics are additive. In contrast, captopril and beta-blockers have a less than additive effect.. Blood pressure is lowered to about the same extent in both standing and supine positions. Orthostatic effects and tachycardia are infrequent but may occur in volume-depleted patients. Abrupt withdrawal of captopril has not been associated ...
Lactacystin is a proteasome inhibitor that interferes with several factors involved in heart remodelling. The aim of this study was to investigate whether the chronic administration of lactacystin induces hypertension and heart remodelling and whether these changes can be modified by captopril or melatonin. In addition, the lactacystin-model was compared with NG-nitro-l-arginine-methyl ester (L-NAME)- and continuous light-induced hypertension. Six groups of three-month-old male Wistar rats (11 per group) were treated for six weeks as follows: control (vehicle), L-NAME (40 mg/kg/day), continuous light (24 h/day), lactacystin (5 mg/kg/day) alone, and lactacystin with captopril (100 mg/kg/day), or melatonin (10 mg/kg/day). Lactacystin treatment increased systolic blood pressure (SBP) and induced fibrosis of the left ventricle (LV), as observed in L-NAME-hypertension and continuous light-hypertension. LV weight and the cross-sectional area of the aorta were increased only in L-NAME-induced hypertension. The

This study is a sequel to a previous study by McGrowder et al. [9] which found that SNAP-treated dogs displayed postprandial hyperglycaemia. Captopril was used as the control drug based on results from a study conducted by Winocour et al. [10] which found that low-dose therapy had no significant effect on blood glucose control in hypertensive insulin-treated diabetic individuals and that it lowers blood pressure by a mechanism which is different from SNAP. The study by McGrowder et al. [9] also reported that SNAP at 20 mg/kg caused significant reduction of the haemodynamic parameter, mean arterial pressure and a significant increase in heart rate via the release of nitric oxide. Captopril at a dose of 20 mg/kg had less of an effect on both mean arterial and heart rate. The mean arterial blood pressure-lowering effect of captopril (an angiotensin converting enzyme inhibitor) is related to a reduction in the peripheral arterial vascular resistance. The hypotensive response to captopril is ...
Renin (REN) expression is required to maintain blood pressure and electrolyte homeostasis. However, the mechanisms by which REN is transcriptionally regulated remain elusive. We reported a functional role for several nuclear receptors (NRs) on REN gene transcription. To identify other candidate NRs that regulate REN, we analyzed a publicly available microarray dataset (GUDMAP Developing Kidney ST1) to compare the expression pattern of REN and the 48 NRs across different kidney cell types. Our analysis revealed 14 NRs exhibiting a similar pattern as REN. We hypothesized that these NRs are co-regulated with REN and can regulate REN transcription. To test this hypothesis, we set up 2 cohorts of mice in which REN expression was either high or low compared to control mice and measured expression of REN and NRs in renal cortex by qPCR. The high-REN cohort was given the ACE inhibitor captopril (100g/kg/day) for 10 days, and the low-REN group was implanted subcutaneously with a deoxycorticosterone acetate
Mercurials are known to induce morphological and functional modifications in kidney mitochondria. In this work we studied in vitro and in vivo the protective effect of captopril on the deleterious effect of Hg(++)-induced nonspecific membrane permeability changes to Ca++ and membrane de-energization. In vivo the administration of captopril prevented the toxic effects of mercury poisoning on membrane permeability, oxidative phosphorylation and Ca++ homeostasis. Moreover, captopril preserves kidney tissue morphology from Hg(++)-induced damage. The protective effect of captopril is most likely related to the existence of a sulfhydryl group in the drug. ...
A study in the Journal of the American Pharmacists Association found that patients with type 2 diabetes taking captopril had a significantly higher risk of suffering from pulmonary adverse drug effects, compared with those taking other angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers. The researchers said the study highlights the importance of considering a medications adverse event profile and how they may affect pulmonary function in infections such as COVID-19.

The authors deplore a recent incident that highlights the impact of the media and the pharmaceutical industry on the practice of medicine. The publication of a study comparing the changes in cholesterol levels and glucose metabolism of hypertensive patients treated with a diuretic and with an angiotensin converting enzyme inhibitor (captopril) was publicized by the pharmaceutical company that manufactures the latter drug. Alarmed by popular media reports that diuretics could raise heart attack risks, thousands of hypertensive patients being treated with diuretics contacted their physicians. A decrease in the number of new prescriptions for oral diuretics occurred in the months after the studys release. Citing data to show that diuretic therapy is still safe, effective, and relatively inexpensive in the management of hypertension, the authors call for physicians to take a stand against prescribing pressures generated by the media and by pharmaceutical industry promotion campaigns.

To explore the effects of captopril on calpain-mediated apoptosis of myocardial cells and cardiac function in diabetic rats, 30 adult male Sprague-Dawley rats were randomly divided into three groups: Negative control (NC group), untreated diabetic rats (DM group) and diabetic rats treated with captopril (Cap group). Diabetes was induced by streptozotocin injection. Captopril was intragastrically administered at a daily dose of 50 mg/kg for 12 weeks; the NC and DM groups received an equivalent volume of saline. After 12 weeks of treatment, left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVDEP), maximal rate of left ventricular pressure increase (+dp/dtmax), maximal rate of left ventricular pressure decrease (-dp/dtmax) and left ventricular mass index (LVMI) were measured. The levels of calpain-1, calpain-2, B-cell lymphoma (Bcl)-2, Bcl-2 associated protein X (Bax) and total caspase-3 were detected in cardiac tissue by western blot analysis. The apoptotic index ...

Cardiovascular diseases are a major cause of death in Western countries. Angiotensin-converting enzyme (ACE) is as a key enzyme in the renin-angiotensin system involved in the regulation of blood pressure, and water and electrolyte balance in the body. ACE not ouly increases the conversion of angiotensin I to the active angiotensin II, but also degrades bradykinin. ACE inhibitors, like captopril, are today first-line treatment in hypertension and heart failure.. We have shown that two structurally different ACE inhibitors, captopril and fosinopril, exhibit anti-atherosclerotic effects in hypercholesterolemic mini pigs. Captopril, but not fosinopril, improved endothelial function in the iliac arteries from the mini pigs.. Bradykinin-induced relaxation of porcine iliac arteries was mediated by bradykinin B2 receptors and the subsequent release of nitric oxide (NO). ACE inhibitors did not affect the bradykinin-induced relaxation, implying that other enzymes than ACE (e. g. carboxypeptidase M; CPM) ...
We investigated the effects of the angiotensin-converting enzyme inhibitor captopril on neurologic outcome in a rat model of incomplete cerebral ischemia. Twenty male Sprague-Dawley rats were anesthetized with 70% nitrous oxide in oxygen and fentanyl (10 micrograms x kg-1 i.v. bolus, 25 micrograms x kg-1 x hr-1 i.v. continuous infusion). Animals in group 1 (n = 10) received no angiotensin-converting enzyme inhibitor while animals in group 2 (n = 10) were given 10 mg x kg-1 i.v. captopril 30 minutes prior to the ischemic period. Ischemia was produced by unilateral carotid artery ligation and hemorrhagic hypotension to 35 mm Hg for 30 minutes. Body temperature, arterial blood gases, and arterial pH were maintained constant. Neurologic outcome was evaluated every 24 hours for 3 days using a graded deficit score (0, normal; 18, stroke-related death). On the third day after ischemia, captopril significantly improved neurologic outcome (median deficit score = 4) compared with controls (median deficit ...
TY - JOUR. T1 - Active and Inactive Renin after SQ 14225 (Captopril) Administration. AU - Goto, Toshikazu. AU - Abe, Keishi. AU - Otsuka, Yoichi. AU - Itoh, Toru. AU - Imai, Yutaka. AU - Satoh, Makito. AU - Omata, Ken. AU - Yoshinaga, Kaoru. PY - 1980/1/1. Y1 - 1980/1/1. N2 - The changes of active and inactive renin in plasma after the oral administration of 25 mg or 50 mg of SQ 14225 (Captopril) were studied in 29 hypertensive patients. Inactive renin was calculated as plasma renin activity (PRA) after cold storage minus PRA before cold storage. The patients were divided into 2 groups, responders and non-responders, according to the response of active renin to Captopril. In 9 responders, the active renin increased markedly while the inactive renin decreased. On the other hand, in 20 non-responders, both renin activities increased only slightly. These results suggest that inactive renin may be converted in vivo to active renin by Captopril.. AB - The changes of active and inactive renin in ...
TY - JOUR. T1 - Hyperkalemia in azotemic patients during angiotensin-converting enzyme inhibition and aldosterone reduction with captopril. AU - Textor, Stephen C.. AU - Bravo, Emmanuel L.. AU - Fouad, Fetnat M.. AU - Tarazi, Robert C.. PY - 1982/11. Y1 - 1982/11. N2 - Thirty-three hypertensive patients with a wide range of renal function were studied during initiation of angiotensin-converting enzyme inhibition with captopril to evaluate changes in potassium levels concomitant with reduction of aldosterone excretion. Ten patients (Group I) with low levels of plasma renin activity had no change in either aldosterone excretion or potassium during the first week of therapy. Twenty-three other patients (Group II) had decreased aldosterone excretion of an average of 63 percent, often reversing secondary hyperaldosteronism. This was associated with a rise in serum potassium from 3.6 ± 0.1 to 4.4 ± 0.1 mEq/liter (p , 0.001). Serum potassium levels during captopril therapy were inversely related to ...
The average (+/-SD) pre-randomisation and 12-week post-randomisation systolic blood pressure for the captopril group were 138.1 (+/-18.19) (95% CI: 131 - 145) and 134.0 (+/- 20.2) (95% CI: 127 - 142), respectively. The corresponding figures for the lisinopril group were 134.0 (+/- 14.7) (95% CI: 128 - 140) and 125.6 (+/- 21.2) (95% CI: 118 - 134), respectively. The average (+/-SD) pre-randomisation and 12-week post-randomisation diastolic blood pressure for the captopril group were 82.4 (+/- 8.8) (95% CI: 79 - 86) and 80.2 (+/- 8.1) (95% CI: 79 -82), respectively. The corresponding figures for the lisinopril group were 84.8 (+/- 7.7) (95% CI: 83 - 86) and 77.5 (+/-8.9) (95% CI: 74 - 81), respectively. No significant differences in blood pressure were discovered either within or among the study groups (p,0.05). The final conversion ratio in the lisinopril group was 4.9 (+/- 1.6) (95% CI: 4.3 - 5.5), which was not significantly different from the initial 5:1 conversion ratio. The groups had ...

OBJECTIVES--To determine the effects of captopril and oxygen on sleep quality in patients with mild to moderate cardiac failure. DESIGN--An open observational study. PATIENTS--12 patients with New York Heart Association class II-III heart failure were studied at baseline. 9 of these patients were then examined at the end of 1 month of treatment with captopril; 9 of the patients were separately assessed during a single night of supplementary oxygen. MAIN OUTCOME MEASURES--Sleep patterns by polysomnography, overnight oximetry, and subjective sleep assessment using visual analogue scores. RESULTS--Abnormal sleep was present in all baseline studies. Complete polysomnograms after treatment with captopril were obtained in 8 patients. Light sleep (stages 1 and 2) was reduced (mean (SEM) 61%(8)% to 48%(6)% actual sleep time, P , 0.05) but slow wave (stages 3 and 4) and REM (rapid eye movement) sleep increased (25%(6)% to 31%(5)%, 14%(2)% to 21%(5)% actual sleep time, P , 0.05).

Captopril/hydrochlorothiazide is an oral medication used to treat high blood pressure. Learn who its for, how it works, its side effects, warnings, and more.
The simple active site inhibition model is shown schematically below. However, in order to address the many early reports of severe side effects, further refinement has led to a new generation of ACE inhibitors that include enalapril. There is a freely available summary of current ACE inhibitors here. The captopril story is an excellent example of how medicinal chemistry developed in the 1970s in particular. It was followed by approaches based on screening large automated libraries of compounds in a methodology called combinatorial chemistry. I note with interest and enthusiasm, the resurgence of Natural Product chemistry in the areas of antibiotics and anti-malarial drugs, and direct you to a nice review of this "renaissance" by Tadesz Molinski, which is free to download here. ...
Pulmonary hypertension (PH) is an incurable condition inevitably resulting in death because of increased right heart workload and eventual failure. PH causes pulmonary vascular remodeling, including muscularization of the arteries, and a reduction in the typically large vascular compliance of the pulmonary circulation. We used a rat model of monocrotaline (MCT) induced PH to evaluated and compared Captopril (an angiotensin converting enzyme inhibitor with antioxidant capacity) and N-acetylcysteine (NAC, a mucolytic with a large antioxidant capacity) as possible treatments. Twenty-eight days aftcr MCT injection, the rats were sacrificed and heart, blood, and lungs were studied to measure indices such as right ventricular hypertrophy (RVH), hematocrit, pulmonary vascular resistance (PVR). vessel morphology and biomechanics. We implemented microfocal X-ray computed tomography to image the pulmonary arterial tree at intravascular pressures of 30, 21,12, and 6 mmHg and then used automated vessel detection
