Effects of nicorandil on experimentally induced gastric ulcers in rats: a possible role of K(ATP) channels. (1/872)

The anti-ulcer effects of nicorandil [N-(2-hydroxyethyl)nicotinamide nitrate ester] were examined on water-immersion plus restraint stress-induced and aspirin-induced gastric ulcers in rats, compared with those of cimetidine. Nicorandil (3 and 10 mg/kg) given orally to rats dose-dependently inhibited the development of acid-related damage (water-immersion- and aspirin-induced gastric lesions) in the models. Cimetidine (50 mg/kg, p.o.) also had anti-ulcer effects in the same models. However, in the presence of glibenclamide (20 mg/kg, i.v.), an antagonist of K(ATP) channels, nicorandil did not inhibit the formation of gastric lesions. Nicorandil (10 mg/kg) given intraduodenally (i.d.), like cimetidine (50 mg/kg), significantly reduced the volume of the gastric content, total acidity and total acid output in the pylorus ligation model. Glibenclamide reversed the changes caused by i.d. nicorandil. I.v. infusion of nicorandil (20 microg/kg per min) significantly increased gastric mucosal blood flow, without affecting blood pressure and heart rate, but the increase in the blood flow was not observed after i.v. treatment with glibenclamide (20 mg/kg). These results indicate that nicorandil administered orally to rats produces the anti-ulcer effect by reducing the aggressive factors and by enhancing the defensive process in the mucosa through its K(ATP)-channel-opening property.  (+info)

Cimetidine transport in brush-border membrane vesicles from rat small intestine. (2/872)

In previous studies, sulfoxide metabolite was observed in animal and human intestinal perfusions of cimetidine and other H2-antagonists. A sequence of follow-up studies is ongoing to assess the intestinal contributions of drug metabolism and drug and metabolite transport to variable drug absorption. An evaluation of these contributions to absorption variability is carried out in isolated fractions of the absorptive cells to uncouple the processes involved. In this report, data is presented on the drug entry step from a study on [3H]cimetidine uptake into isolated brush-border membrane vesicles from rat small intestine. A saturable component for cimetidine uptake was characterized with a Vmax and Km (mean +/- S.E.M.) of 6.1 +/- 1.5 nmol/30s/mg protein and 8.4 +/- 2.0 mM, respectively. Initial binding, and possibly intravesicular uptake, was inhibited by other cationic compounds including ranitidine, procainamide, imipramine, erythromycin, and cysteamine but not by TEA or by the organic anion, probenecid. Initial uptake was not inhibited by amino acids methionine, cysteine, or histidine, by the metabolite cimetidine sulfoxide, or by inhibitors of cimetidine sulfoxidation, methimazole, and diisothiocyanostilbene-2,2'-disulfonic acid. Equilibrium uptake was inhibited by ranitidine, procainamide, and cysteamine but not by erythromycin or imipramine. Initial cimetidine uptake was stimulated by an outwardly directed H+ gradient, and efflux was enhanced by an inwardly directed H+ gradient. Collapse of the H+ gradient as well as voltage-clamping potential difference to zero significantly reduced initial cimetidine uptake. The data is supportive of both a cimetidine/H+ exchange mechanism and a driving-force contribution from an inside negative proton or cation diffusion potential.  (+info)

Glomerular filtration rate estimation from plasma creatinine after inhibition of tubular secretion: relevance of the creatinine assay. (3/872)

BACKGROUND: Estimation of glomerular filtration rate (GFR) from plasma creatinine concentration after inhibition of tubular creatinine secretion with cimetidine provides a good assessment in patients with various nephropathies and with non-insulin-dependent diabetes mellitus (NIDDM). The aim of this study was to compare cimetidine-aided GFR estimations using various creatinine assays. METHODS: In 30 outpatients with NIDDM GFR was measured as the urinary clearance of continuously infused [125I]iothalamate. Plasma creatinine concentration was analysed after oral cimetidine with an alkaline picrate (AP) method, with an enzymatic (PAP) assay and with HPLC. GFR estimations were calculated with the Cockcroft Gault formula (CG). RESULTS: AP creatinine concentrations were significantly higher than PAP or HPLC values. GFR estimations by AP (CG(AP) 66 +/- 19 ml/min/1.73 m2, mean SD) were significantly lower than GFR (89 +/- 30), whereas CG(PAP) (85 +/- 30) and CG(HPLC) (84 +/- 34 ml/min/1.73 m2) were not. Bland and Altman analysis showed a difference between CG(AP) and GFR of -22.4 +/- 17.7 ml/min/1.73 m2; this difference becomes larger when the GFR increases. The difference between CG and GFR was only -3.8 +/- 14.8 ml/min/1.73 m2 for PAP and -4.4 +/- 17.5 ml/min/1.73 m2 for HPLC, without any systematic difference. CONCLUSION: A good assessment of the GFR from plasma creatinine after cimetidine administration is possible when creatinine is measured with an enzymatic assay or with the less convenient HPLC method. The more widespread and cheaper alkaline picrate assay is not suitable for GFR-estimation.  (+info)

Drug interactions of H2-receptor antagonists involving cytochrome P450 (CYPs) enzymes: from the laboratory to the clinic. (4/872)

This paper reviews the main steps in the research of the interactions of H2-receptor antagonist drugs with cytochrome P450 (CYP) enzymes. Cimetidine, ranitidine, and related compounds are used as examples. The results from in vitro studies are related to the observed clinically significant in vivo drug-drug and drug-chemical interactions. Uses of the in vitro results are discussed for the interpretation and possible prediction of drug-drug interactions, which may be important in developing new drugs. Other approach in the use of the in vitro data is to prevent undesirable and toxic actions of drugs related to the catalytic activity of CYP enzymes. In the case of H2-receptor antagonists, the inhibition of the metabolic reactions due to the binding of the drugs with the enzymes was used to avoid side effects of co-administered drugs. The in vitro metabolic studies using recombinant human as well as animal CYP enzymes are now widely used as model syste ms for designing new drugs with improved therapeutic properties.  (+info)

Histamine response and local cooling in the human skin: involvement of H1- and H2-receptors. (5/872)

AIMS: Histamine may contribute locally to cutaneous blood flow control under normal and pathologic conditions. The objective of this study was to observe the influence of skin temperature on histamine vasodilation, and the roles of H1-and H2-receptors using novel noninvasive methods. METHODS: Eleven healthy subjects received, double-blind, single doses of the H1-receptor antagonist cetirizine (10 mg), cetirizine (10 mg) plus the H2-receptor antagonist cimetidine (400 mg), or placebo on separate occasions. Histamine was dosed cumulatively by iontophoresis to the forearm skin at 34 degrees C and 14 degrees C. Laser-Doppler flux (LDF) was measured at the same sites using customised probeholder/iontophoretic chambers with Peltier cooling elements. Finger mean arterial pressure (MAP) was measured and cutaneous vascular conductance calculated as LDF/MAP. RESULTS: Histamine vasodilation was reduced in cold skin. Cetirizine shifted the histamine dose-response at both temperatures: statistically significantly at 14 degrees C only. Combined H1- and H2-receptor antagonism shifted the response significantly at both temperatures. CONCLUSIONS: H1- and H2-receptors mediate histamine-induced skin vasodilation. The sensitivity of these receptors, particularly the H1- receptor, is attenuated at low skin temperature. Whether the reduced effect in cold skin represents specific receptor or postreceptor desensitization, or nonspecific attenuation of cutaneous vasodilation remains to be elucidated.  (+info)

Antiulcer effect of lafutidine on indomethacin-induced gastric antral ulcers in refed rats. (6/872)

Lafutidine is a new type antiulcer agent with antisecretory and gastroprotective activities. We investigated the effect of lafutidine on indomethacin-induced antral ulcer in refed rats. Subcutaneous indomethacin injection resulted in the formation of gastric antral ulcer. Lafutidine (1-10 mg/kg, p.o.) reduced the area of ulcer in a dose-dependent manner when administered immediately after the indomethacin injection. Capsaicin at 3 mg/kg, p.o. and 16,16-dimethyl prostaglandin E2 at 3 microg/kg, p.o. also reduced the ulcer area. Chemical deafferentation of capsaicin-sensitive neurons or N(G)-nitro-L-arginine treatment aggravated the ulcer formation and abolished the preventive effect of lafutidine and capsaicin. After the induction of gastric ulcer, lafutidine given twice daily for 2.5 days reduced the area of ulcer in a dose-dependent manner with a significant effect at 10 mg/kg, p.o., as compared with that of the control group. In chemically-deafferentated rats, lafutidine did not show any healing effect. Cimetidine (30 mg/kg, p.o.) and famotidine (1 mg/kg, p.o.) had no significant effect on indomethacin-induced antral ulcer. These results may suggest that lafutidine, unlike cimetidine and famotidine, can prevent the indomethacin-induced antral ulcer formation and accelerate the healing of the ulcer in refed rats through mechanisms involving the capsaicin-sensitive afferent neurons and nitric oxide.  (+info)

Use of cimetidine, omeprazole, and ranitidine in pregnant women and pregnancy outcomes. (7/872)

Evidence documenting the safety of acid-suppressing drugs in pregnancy is very limited. The authors assessed the prevalence of congenital malformations in first trimester-exposed pregnancies to cimetidine, omeprazole, and ranitidine and compared it with nonexposed pregnancies between 1991 and 1996. Two different sources were used, the United Kingdom General Practice Research Database and the Italian Friuli-Venezia Giulia Health Database. The final study cohort included 1,179 pregnancies from the United Kingdom and 1,057 from Italy. Abortions or ectopic pregnancies were not included. There were 20 stillbirths and 2,261 live-born babies in both cohorts combined, with 100 offspring identified with a malformation. The overall malformation rate was 4.4%. The relative risks for nongenetic congenital malformations associated with the use of cimetidine, omeprazole, and ranitidine were 1.2 (95% confidence interval (CI): 0.6, 2.3), 0.9 (95% CI: 0.3, 2.2), and 1.4 (95% CI: 0.8, 2.4), respectively, compared with the nonexposed. No specific grouping in the distribution of malformations was observed in any of the three exposed groups. Moreover, no relation was found between drug exposure and preterm delivery or growth retardation. These findings suggest that the use of acid-suppressing drugs during the first trimester of pregnancy is not associated with a major teratogenic risk.  (+info)

Does cimetidine improve prospects for cancer patients?. A reappraisal of the evidence to date. (8/872)

BACKGROUND: Evidence first appeared in 1988 that cimetidine as an adjuvant may improve the survival of severely ill gastro-intestinal cancer patients when given peri- or postoperatively. Since then, several studies have appeared which suggest an anticancer activity for cimetidine, although few attempts have been made to corroborate their findings in large, placebo-controlled, double-blind studies. METHOD: We reviewed the literature concerning cimetidine's potential anticancer activity, particularly with regard to gastro-intestinal cancers. RESULTS: Most studies suggest that cimetidine may improve the outcome in cancer patients by a three-pronged mechanism involving (1) inhibition of cancer cell proliferation; (2) stimulation of the lymphocyte activity by inhibition of T cell suppressor function, and (3) inhibition of histamine's activity as a growth factor in tumours. CONCLUSION: Bearing in mind the experimental evidence, as well as the potential and excellent safety profile of cimetidine, more studies are required and justified to clarify cimetidine's protherapeutic activity.  (+info)

TY - JOUR. T1 - Cimetidine Does Not Inhibit Indomethacin-Induced Small Bowel Ulceration in the Rat. AU - Kauffman, Gordon L.. AU - Foley, Kevin. AU - Grossman, Morton I.. PY - 1979/1/1. Y1 - 1979/1/1. N2 - In earlier studies, cimetidine was found to protect against acetylsalicylic acid-induced gastric mucosal lesions by a mechanism other than inhibition of gastric acid secretion. The present study examined the possibility that cimetidine might protect against the intestinal mucosal injury produced by indomethacin. Small intestinal ulceration produced by oral indomethacin (20 mg kg-1) was studied in rats treated with 0.15 M NaCl (control); 80 mg kg-1 cimetidine; 400 mg kg -1 cimetidine; and 100 μug kg-1 16-16 dimethyl prostaglandin E2. The treatments were given 30 min before and 8 hr after indomethacin. Confirming previous studies, 16-16 DMPGE2 significantly (P , 0.01) reduced the number of lesions and the sum of the lengths of ulcers per rat when compared to the control group. Neither dose of ...
Cimetidine, sold under the brand name Tagamet among others, is a histamine H2 receptor antagonist that inhibits stomach acid production. It is available over-the-counter and is mainly used in the treatment of heartburn and peptic ulcers. The development of longer-acting H2 receptor antagonists with fewer drug interactions and adverse effects, such as ranitidine and famotidine, decreased the use of cimetidine, and though it is still used, cimetidine is no longer among the more widely used of the H2-receptor antagonists.[citation needed] Cimetidine was discovered in 1971 and came into commercial use in 1977. Cimetidine was approved in the United Kingdom in 1976, and was approved in the United States by the Food and Drug Administration for prescriptions in 1979.[citation needed] Cimetidine is used to inhibit stomach acid production and is used in the treatment of heartburn and peptic ulcers. Some evidence suggests cimetidine could be effective in the treatment of common warts, but more rigorous ...
Forty five patients with refractory oesophagitis, defined as persisting erosive changes or ulceration despite a minimum of three months treatment with cimetidine 3.2 g daily or ranitidine 0.9 g daily, were treated in an open trial with omeprazole 40 mg daily for up to eight weeks. Endoscopically defined healing was observed in 73% of patients after four weeks treatment and in 91% after eight weeks treatment. Symptoms were completely relieved in 60% of patients, improved in 34%, unchanged in 4%, and worsened in 2%. After healing patients returned to maintenance treatment with cimetidine 1.6-3.2 g daily, depending on the severity of their illness before treatment with omeprazole. By six months and 12 months only 55% and 33% of patients respectively were still in remission. This study suggests that when erosive oesophagitis is refractory to treatment with high dose cimetidine or ranitidine, treatment with omeprazole 40 mg daily for up to eight weeks is effective in inducing healing and relieving ...
The effect of two doses of cimetidine, 400 mg at night and 400 mg bd, on the protection of indomethacin (50 mg tid) induced mucosal damage was evaluated in a double blind study in patients with acute musculoskeletal disorders. Endoscopic mucosal lesions were scored before and after five to seven days of treatment. One hundred and ninety one patients were endoscoped before the trial, 34 (17.8%) had greater than one erosion and were not recruited. Forty patients were excluded for non-compliance, or lost to follow up. At the second endoscopy, oesophageal, and fundic damage was negligible. Gastric and duodenal lesion score in patients treated with cimetidine 400 mg bd: 2.7 (0.5) (SE); n = 42) was significantly lower (p less than 0.0122) than in placebo treated patients: 6.1 (0.9) (n = 50) or in patients treated with cimetidine 400 mg at night 7.1 (0.8) (n = 21). Cimetidine 400 mg bd provided significant protection for the duodenum, but its protection of antral mucosa did not reach statistical ...
An Unexpected Anti-Cancer Agent. The first studies to hint at cimetidines effectiveness against cancer were published in the late 1970s. Although scientists initially thought that cimetidine worked by enhancing immune function, later studies showed that cimetidine functions via several different pathways to inhibit tumor cell proliferation and metastasis. In a prospective, randomized, placebo-controlled study in 1988, 181 patients with gastric cancer received cimetidine (400 mg, twice daily) or placebo for two years or until death. Those given cimetidine had a significantly prolonged survival rate compared to the placebo group, particularly patients with more serious disease.1. In a 1994 study, just seven days of cimetidine treatment (400 mg twice daily for five days preoperative and intravenously for two days post-operative) in colorectal cancer patients decreased their three-year mortality rate from 41% to 7%. In addition, tumors in the cimetidine-treated patients had a notably higher rate of ...
The efficacy of Cimetidine in the prevention and treatment of stress-induced gastroduodenal lesions was evaluated in a randomized, double-blind, placebo-controlled study in which serial endoscopy was used to examine patients without clinical evidence of bleeding who were admitted to a medical intensive care unit. Endoscopy showed that 14 of 21 patients treated with Cimetidine, compared with 5 of 18 patients treated with placebo, had normal or improved gastroduodenal mucosa (p , 0.05). Endoscopic signs of bleeding cleared or did not develop in 20 patients treated with Cimetidine and in 11 patients treated with placebo (p , 0.01). Significantly fewer blood transfusions were given to patients with endoscopic signs of bleeding in the cimetidine-treated group (0.5 ±0.3 [SE] units) than in placebo-treated patients (4.5 ±1.5 units; p , 0.05). The mortality rate was not statistically different between treatment groups. By preventing established gastroduodenal stress lesions from progressing in ...
Cimetidine is a powerful H2 receptor antagonist originally designed to treat ulcers by blocking the acid producing cells in the stomach. In the study three groups of rabbits were simultaneously induced with experimental periodontitis using P. gingivalis and treated with varying levels of topically applied cimetidine three times a week over a six-week period. Results showed that topical application of cimetidine at all concentrations inhibited inflammation and bone loss by approximately 90 ...

Clinical studies have indicated that suppression of nocturnal acid is the most important factor in duodenal ulcer healing (see CLINICAL PHARMACOLOGY, Antisecretory Activity, Acid Secretion). This is supported by recent clinical trials (see CLINICAL PHARMACOLOGY, Clinical Trials, Active Duodenal Ulcer). Therefore, there is no apparent rationale, except for familiarity with use, for treating with anything other than a once-daily at bedtime dosage regimen.. In a U.S. oral dose-ranging study of 400 mg at bedtime, 800 mg at bedtime and 1600 mg at bedtime, a continuous dose response relationship for ulcer healing was demonstrated.. However, 800 mg at bedtime is the dose of choice for most patients, as it provides a high healing rate (the difference between 800 mg at bedtime and 1600 mg at bedtime being small), maximal pain relief, a decreased potential for drug interactions (see PRECAUTIONS, Drug Interactions) and maximal patient convenience. Patients unhealed at four weeks, or those with persistent ...
Dyspepsia, a poorly defined syndrome of episodic or recurrent upper abdominal discomfort after eating, has an estimated prevalence of 20% to 30% in the general population. The pathophysiology of this disorder is unknown. Postulated mechanisms include gastric acid hypersecretion, gastric motility disorder, Helicobacter pylori infection, and psychogenic stress. The investigation of dyspepsia is limited to patients with systemic signs or symptoms that suggest anatomic disease; otherwise, the treatment of dyspepsia is empiric. Results of previous randomized trials have generally failed to show any advantage of antacids or cimetidine over placebo (1), although a more recent trial found a benefit of cimetidine for relief of pain (2). Johannessen and colleagues compared on-demand cimetidine with placebo in treating the symptoms of dyspepsia. Their n-of-1 design addresses a limitation of previous studies: A subgroup of responders may have been lost in the random error associated with a majority of ...

Cimetidine is an H2-receptor antagonist that inhibits gastric acid secretion. In pregnancy, the antihistamine is primarily used for the treatment of peptic ulcer disease and for the prevention of gastric acid aspiration (Mendelsons syndrome) prior to delivery.. In studies with multiple animal species, no evidence of impaired fertility or teratogenesis was observed with doses up to 40 times higher than the usual human dose (1). Cimetidine does have weak antiandrogenic effects in animals, as evidenced by a reduction in the size of testes, prostatic glands, and seminal vesicles (2,3), and in humans, by reports of decreased libido and impotence (4). Conflicting reports on the antiandrogenic activity in animals exposed in utero to cimetidine have been published (5,6,7,8 and 9).. Three references, all from the same research group, described the effects on male rats of exposure to cimetidine from gestation up to the time of weaning (5,6 and 7). The rats had decreased weights of testicles, prostate ...
I just got a call back from Eltons vet. He said he consulted with his neurologist and they both agree that cimetidine will not do what prilosec will in reducing the CSF fluid.

Histamine stimulation of adenylate cyclase activity in broken cells isolated from guinea pig gastric mucosa was competitively inhibited by the thiazole derivative ICI 125,211 and the furane derivative ranitidine, with pA2 of 7.62 (Ki = 2.39 x 10-8 M) and pA2 of 6.90 (Ki = 1.25 x 10-7 M), respectively, i.e., potencies 19 times and 4 times superior to that of the classical H2-receptor antagonist cimetidine (pA2 = 6.34; Ki = 4.57 x 10-7 M). These results are consistent with the reported pharmacological potencies of the antagonists on guinea pig right atrium and on gastric acid secretion in vivo. Thus, the requirement of an imidazole ring in the structure of H2-receptor antagonists can be definitely ruled out.. ...

Secretion of acid by the stomach depends on the binding of gastric acetylcholine and histamine to their respective receptor on the parietal cell surface. Blocking either of these leads to a reduction in acid secretion. H1 receptors are located on blood vessels, smooth muscle and in the skin. H2 receptor are located in the stomach and stimulation results in gastric acid secretion. Drugs which block H2 receptors were developed in several stages. The first member of this group to be made commercially available was cimetidine which was released in the UK in November 1976. Since then, it and the other available H2 receptor antagonist ranitidine, which was marketed in 1981, have become widely used. (2). Cimetidine. Cimetidine is used in the short-term treatment of active, benign, gastric ulcer. In studies in patients with gastric ulcers receiving supplemental antacid cimetidine promoted healing of ulcers in up to 70% of patients after 4 weeks and in 66-100% of patients after 6 weeks. In controlled ...
Available evidence indicates that there are two types of Na(+)-H+ exchangers, type A (housekeeping type) and type B (epithelial or apical type), in mammalian cells. We have recently reported, using isolated membrane vesicles, that these two types can be differentiated by their relative sensitivities to inhibition by clonidine and cimetidine [Kulanthaivel, Leibach, Mahesh, Cragoe & Ganapathy (1990) J. Biol. Chem. 264, 1249-1252]. The present study was undertaken to determine whether this approach is also effective in cultured cells. The JAR human placental choriocarcinoma cell line and the opossum kidney (OK) cell line, when grown as confluent monolayer cultures on an impermeable plastic support, express Na(+)-H+ exchanger activity which is measurable by determining Na+ uptake into the cells from the culture medium. The JAR cell Na(+)-H+ exchanger was found to be about 100 times more sensitive to inhibition by dimethylamiloride than the OK cell Na(+)-H+ exchanger. Inhibition studies with ...

The present study examined the effect of histamine H2-receptor antagonists and exogenous histamine on growth of malignant melanoma implant in mice. Drugs were administered to B16BL6 malignant-melanoma-implanted syngeneic mice, and the tumor volume was measured throughout the experiments. Cell proliferation was assessed by MTT assay and mRNA expression was determined by RT-PCR. Both roxatidine and cimetidine significantly suppressed growth of B16BL6 implant compared with vehicle. On the other hand, systemically administered histamine significantly stimulated growth of B16BL6 implants. In addition, the histamine-stimulated B16BL6 implant growth was markedly suppressed by co-administration of cimetidine in a dose-dependent manner. H2-receptor antagonists, however, failed to affect in vitro proliferation of B16BL6 cells. H2-receptor mRNA was detected in B16BL6 implants but not in the cell line. These results indicated that both endogenous and exogenous histamine have ability to stimulate growth of malignant

The biology of CYPs is complex. It reveals its secrets only in a committed relationship, and the multiplicity of CYP isoforms and their myriad products elude a casual grasp. However, this complexity belies the widespread physiological, pathological, and toxicological significance of these enzymes. The CYPs catalyze the controlled addition of molecular oxygen to carbon-carbon bonds, which is one of the most elegant reactions devised by nature and is used by all organisms to remove and detoxify foreign chemicals. It is, however, a Faustian bargain. The reaction proceeds via the formation of an alkoxyl radical-like intermediate and leaks superoxide and hydrogen peroxide,7 both of which could be highly toxic. Consequently, CYP-based detoxification of alcohols, drugs, and chemicals often results in increased radical generation and causes oxidative stress.7 The protective effects of CYP inhibitors (chloramphenicol, cimetidine, and sulfaphenazole) against myocardial ischemic injury have been linked to ...

The present study has shown that cimetidine is a weak, reversible inhibitor of CYP2D6 in vitro, a finding consistent with reports from other laboratories (Martinez et al., 1999; Furuta et al., 2001). Additionally, evidence presented here suggests that cimetidine acts as a mechanism-based inactivator of CYP2D6. A 31% decrease in recombinant CYP2D6 activity was observed following preincubation with cimetidine, NADPH, and antioxidants. This loss in activity was time-dependent and was consistent with the catalysis-dependent formation of a reactive metabolite or metabolite-intermediate species, as previously demonstrated in animal studies with CYP2C11 and CYP2C6 (Chang et al., 1992b; Levine and Bellward, 1995; Levine et al., 1998). Furthermore, inactivation of recombinant CYP2D6 was attenuated by quinidine. As a competitive inhibitor of CYP2D6, quinidine would be able to reduce the formation of the putative inactivating species in a concentration-dependent manner if CYP2D6-mediated metabolism is ...
1. Cimetidine pretreatment of male Sprague-Dawley rats caused a significant increase in the specific content of total hepatic cytochrome P-450, supporting the hypothesis that this H2-receptor antagonist has monooxygenase induction effects. 2. Quantitative ultrastructural studies of liver of cimetidine-pretreated animals also supported this hypothesis in showing a significant proliferation of smooth endoplasmic reticulum. These ultrastructural changes were qualitatively similar to those produced by treatment of rats with phenobarbital, a well-characterized monooxygenase-inducing agent whose effects were studied for comparative purposes. 3. Competitive inhibition of metoprolol αhydroxylation by cimetidine in liver microsomes prepared from untreated animals (Ki = 18.8 μM) was also demonstrated. 4. These results allowed testing of the hypothesis (Burnet el al. 1986) that inhibition of a defined monooxygenase should lead to induction of the synthesis of the relevant cytochrome P-450 isozyme. 5. The ...
Category: Histamine H2-receptor antagonists; antiulcer agents, gastric secretion inhibitors. Information for pharmacists: 1. These relatively new drugs may be preferred to other antiulcer agents because of their convenience and lack of effect on gastrointestinal motility. 2.Cimetidine, Ranitidine or Famotidine may be administered to treat peptic ulcers or hypersecretory states.
Materials. Famotidine and probenecid were purchased from Nacalai Tesque (Kyoto, Japan), and cimetidine and ranitidine were purchased from Sigma-Aldrich (St. Louis, MO). The purity of famotidine, cimetidine, and ranitidine was more than 98%, and that of probenecid was more than 95%. All other chemicals were of analytical grade and commercially available.. Establishment of Transfectants and Cell Culture. The stable transfectants expressing human OAT1 and OAT3 (Tahara et al., 2005) and OCT (Goralski et al., 2002; Schlatter et al., 2002) were established previously. Construction of hOAT2- and rOat3-stable transfectants was carried out as follows. The full coding region of hOAT2 was amplified from human liver cDNA by reverse transcription-polymerase chain reaction following the reported sequence given by accession number NM 006672. Full-length hOAT2 was subcloned into mammalian expression vector pcDNA3.1(+) (Invitrogen, Carlsbad, CA). The construct of pcDNA3.1(+) containing rOat3 was established ...
  This study investigated the antiulcer activity of aqueous extract of unripe Musa paradisiacal (plantain) peels in rats using ethanol, aspirin, indomethacin and pyloric ligation-induced ulcer models. Fresh peels of M. paradisiaca were extracted in hot water and the yield lyophilised. Distilled water, standard drugs and extract were injected intraperitoneally before inducing ulcer. Lethality test and quantitative phytochemical analyses were also carried out using standard techniques. Results showed that the extract at 50, 100 and 200 mg/kg wt offered 73.87, 80.18 and 81.98% protection, respectively against ethanol-induced ulcer, whereas cimetidine (50 mg/kg) produced 72.07% ulcer protection. There was no significant difference (p > 0.05) between the various groups. The extract also inhibited aspirin-induced ulcer whereas omeprazole (20 mg/kg) significantly enhanced aspirin-induced ulcer. Similar to cimetidine, the extract did not inhibit indomethacin-induced ulceration. Extract (50, 100,

Pirenzepine: An antimuscarinic agent that inhibits gastric secretion at lower doses than are required to affect gastrointestinal motility, salivary, central nervous system, cardiovascular, ocular, and urinary function. It promotes the healing of duodenal ulcers and due to its cytoprotective action is beneficial in the prevention of duodenal ulcer recurrence. It also potentiates the effect of other antiulcer agents such as CIMETIDINE and RANITIDINE. It is generally well tolerated by patients.
Cimetidine was first marketed in the United Kingdom in 1976, and in the U.S. in August 1977; therefore, it took 12 years from initiation of the H 2 receptor antagonist program to commercialization. By 1979, Tagamet was being sold in more than 100
Take Furadantin exactly as prescribed by your doctor. The recommended dose for treating urinary tract infections (UTIs) in adults is 50 to 100 mg four times daily, continued for at least three days after the infection has cleared. For long-term treatment to prevent UTIs in adults, often just 50 or 100 mg once daily at bedtime is sufficient. The recommended dosage for treating urinary tract infections in children (age one month and older) is based on body weight. Furadantin should be taken with food, as food increases the absorption of this antibiotic. Take this medication by mouth, with food or milk ...

Many of the molecules contain more than one ionizable group. Only the pKa values of the amine indicated in Eckert and Klamts Table 3 are computed and the protonation states are prepared according standard pKa values. For example, for phenylalanine the carboxyl group is deprotonated because the "standard" pKa values of a carboxyl group (e.g. in acetic acid) is lower than the standard pKa values of a primary amine (e.g. ethylamine). Notice that the cyanoguanidine group in cimetidine has a pKa value of about 0 and is therefore deprotonated when the imidazole group titrates. Eckert and Klamt characterised the histamine pKa value of 9.7 as an amidine pKa and the thenyldiamine pKa as a pyridine pKa. This is corrected to a primary amine and tertiary amine, respectively. Also, the experimental pKa values of morphine and niacin are changed to 8.2 and 4.2, respectively, while the remaining experimental pKa values are taken from Eckert and Klamt ...
The each line in the .smiles files is the name of the molecule followed by a SMILES strings, the name is used to construct the filename, and the subsequent workflow makes some assumptions about the filenames. When I deprotonoate carboxyl group I add a "-" to the filename, e.g. "Phenylalanine-", in the table_3.smmiles and protoam adds a "+" to the filename, e.g. "Phenylalanine-+". Molecules in the table_3++.smiles file will have names like.e.g Procaine++. If more than one nitrogen is protonated protam.py adds "_1" and "_2", etc., e.g. "Histamine+_1". When I make tautomers I add "_1" or "_A", etc., e.g. "Cimetidine+_A". (So in principle you could have, e.g. "name_A_1", but that didnt happen in practise). Some manual editing is required for everything to come out right ...

First, lets look at the clear failure to replicate (#2). The original paper reported the effects of a tumor-penetrating peptide (short protein), iRGD peptide, which in the paper increased cellular uptake of the chemotherapy agent doxorubicin in a xenograft model of prostate cancer. A xenograft model involves injecting human tumor cells into immunosuppressed mice and measuring their growth and the ability of the intervention tested to inhibit or reverse that growth. Basically, the Replication Study failed to find statistically significant differences in the penetrance of doxorubicin into the tumor cells, the tumor weight for mice treated with DOX and iRGD compared to DOX alone, or a measure of programmed cell death (apoptosis).. Neither of the two studies reported to be replicated (#1 and #3) was exactly a resounding replication, either. For example, in #3, the results were mixed, as described in an accompanying commentary. In the original paper, for example, the authors noted that cimetidine ...
