Inhibitory innervation of cat sphincter of Oddi. (1/10578)

1 Electrical stimulation with trains of 0.1-0.2 ms pulses of the cat isolated sphincter of Oddi inhibited the spontaneous contractile activity and lowered base-line tension considerably. A contraction usually followed the period of stimulation. 2 These inhibitory effects were prevented by tetrodotoxin 0.1-0.5 mug/ml but were not reduced by hexamethonilm, morphine, or blockade of alpha- or beta-adrenoreceptors of cholinoceptors with phenoxy-benzamine propranolol or atropine, respectively. 3 Adenosine-5'-triphosphate (ATP) and adenosine-5'-diphosphate (ADP) inhibited the spontaneous sphincter activity and caused relaxation thus mimicking the effects of the C-terminal octapeptide of cholecystokinin (C8-CCK), isoprenaline and prostaglandin E1 and E2. 4 ATP alone (greater than 100 mug/ml) or ATP (greater than 10 mug/ml) plus dipyridamole (1 mug/ml), relaxed the sphincter to the same degrees as did the field stimulation. 5 In sphincter maximally contracted by acetylcholine, the effect of stimulation was more marked than that recorded in uncontracted preparations. 6 The present findings suggest that the sphincter of Oddi receives inhibitory nerves that are neither cholinergic nor adrenergic.  (+info)

Effect of morphine and naloxone on priming-induced audiogenic seizures in BALB/c mice. (2/10578)

1 Morphine (1-200 mg/kg s.c.) reduced the incidence and prolonged the latency of priming-induced audiogenic siezures in a dose-dependent manner. 2 This effect was reversed by naloxone (1 and 2 mg/kg) although naloxone was itself inactive. 3 This priming-induces seizure model may be useful in the study of tolerance and physical dependence.  (+info)

Carcinogenicity of triethanolamine in mice and its mutagenicity after reaction with sodium nitrite in bacteria. (3/10578)

Mice fed a diet containing 0.3 or 0.03% triethanolamine developed malignant tumors. Females showed a high incidence of tumors in lymphoid tissues, while this type was absent in males. Tumors in other tissues were produced at a considerable rate in both sexes, but no hepatoma was found. Triethanolamine was not mutagenic to Bacillus subtilis by itself, but it became mutagenic after reacting with sodium nitrite under acidic conditions or when the mixture was heated. Although N-nitrosodiethanolamine, a known carcinogen and mutagen, was detected in the reaction mixture by thin-layer chromatography, it may not be the main mutagenic product, because the product was a stable and direct mutagen and its mutagenic activity was destroyed by liver enzymes, unlike N-nitrosodiethanolamine. The lethal and mutagenic DNA damages produced by this unidentified product were susceptible to some extent to the repair functions of the bacteria.  (+info)

Determination of pyrolysis products of smoked methamphetamine mixed with tobacco by tandem mass spectrometry. (4/10578)

Distinct and combined vascular effects of ACE blockade and HMG-CoA reductase inhibition in hypertensive subjects. (5/10578)

Hypercholesterolemia and hypertension are frequently associated with elevated sympathetic activity. Both are independent cardiovascular risk factors and both affect endothelium-mediated vasodilation. To identify the effects of cholesterol-lowering and antihypertensive treatments on vascular reactivity and vasodilative capacity, we studied 30 hypercholesterolemic hypertensive subjects. They received placebo for 4 weeks, either enalapril or simvastatin for 14 weeks, and, finally, both medications for an additional 14 weeks. Postischemic forearm blood flow (MFBF) and minimal vascular resistance (mFVR) were used as indices of vasodilative capacity and structural vascular damage, respectively. Total (resting-stress-recovery phases) cardiovascular (blood pressure [BP] and heart rate [HR]) and regional hemodynamic (FBF and FVR) reactivity to stressful stimuli were calculated as area-under-the-curve (auc) (valuextime). Compared with baseline levels, simvastatin reduced total (TOT-C) and LDL cholesterol (LDL-C) (1.27 mmol/L, P<0.001 and 1.33 mmol/L, P<0.001, respectively). Enalapril also reduced TOT-C and LDL-C (0.6 mmol/L, P<0.001 and 0.58 mmol/L, P<0.05, respectively). MFBF was increased substantially by both treatments (P<0.001). Enalapril had a greater effect (-1.7 arbitrary units (AU), P<0.001) than simvastatin (-0.6 AU, P<0.05) on mFVR. During stress, FBF increased more with enalapril (4.4 FBFxminutes, P<0.001) than with simvastatin (1.8 FBFxminutes, P<0.01). Conversely, FVR stress response was reduced more with enalapril (9.1 FVRxminutes, P<0.001) than with simvastatin (2.9 FVRxminutes, P<0.01). During combination treatment, a significant (0.001>P<0.05) additive effect on hypercholesterolemia, structural vascular damage, BP, and FVR was shown. The findings suggest that angiotensin-converting enzyme (ACE) inhibition induces a larger reduction than HMG-CoA reductase blockade in vascular reactivity and structural damage in hypercholesterolemic hypertensive subjects.  (+info)

Ergoline derivative LEK-8829-induced turning behavior in rats with unilateral striatal ibotenic acid lesions: interaction with bromocriptine. (6/10578)

LEK-8829 [9,10-didehydro-N-methyl-(2-propynyl)-6-methyl-8- aminomethylergoline bimaleinate] is an antagonist of dopamine D2 receptors and serotonin (5-HT)2 and 5-HT1A receptors in intact animals and a D1 receptor agonist in dopamine-depleted animals. In the present study, we used rats with unilateral striatal lesions with ibotenic acid (IA) to investigate the dopamine receptor activities of LEK-8829 in a model with innervated dopamine receptors. The IA-lesioned rats circled ipsilaterally when challenged with apomorphine, the mixed agonist on D1/D2 receptors. LEK-8829 induced a dose-dependent contralateral turning that was blocked by D1 receptor antagonist SCH-23390. The treatment with D1 receptor agonist SKF-82958 induced ipsilateral turning, whereas the treatment with D2 receptor antagonist haloperidol induced contralateral posture. The combined treatment with SKF-82958 and haloperidol resulted in a weak contralateral turning, indicating the possible receptor mechanism of contralateral turning induced by LEK-8829. Bromocriptine induced a weak ipsilateral turning that was blocked by haloperidol. The ipsilateral turning induced by bromocriptine was significantly potentiated by the coadministration of a low dose but not by a high dose of LEK-8829. The potentiation of turning was blocked either by SCH-23390 or by haloperidol. The potentiation of ipsilateral turning suggests the costimulation of D2 and D1 receptors by bromocriptine and LEK-8829, respectively, whereas the lack of potentiation by the highest dose of LEK-8829 may be explained by the opposing activity of LEK-8829 and bromocriptine at D2 receptors. We propose that the D2 and 5HT2 receptor-blocking and D1 receptor-stimulating profile of LEK-8829 is promising for the treatment of negative symptoms of schizophrenia.  (+info)

Discriminative stimulus effects of naltrexone after a single dose of morphine in the rat. (7/10578)

The discriminative stimulus effects of an acute morphine (MOR) --> naltrexone (NTX) combination were characterized and compared with the stimulus effects of NTX-precipitated and spontaneous withdrawal from chronic MOR administration. Adult male Sprague-Dawley rats (n = 6-8) were trained to discriminate between two drug treatments in a discrete-trial avoidance/escape procedure: MOR (10 mg./kg, s.c., 4 h) --> NTX (0.3 mg/kg, s.c., 0.25 h) versus saline (SAL, 1 ml/kg, s. c., 4 h) --> NTX (0.3 mg/kg, s.c., 0.25 h). Subjects responded only on the SAL --> NTX-appropriate lever when SAL was given 3.75 h after MOR or 3.75 h before any dose of NTX (0.3-100 mg/kg). Responding was dose dependent and MOR --> NTX-appropriate when NTX (0.01-0.1 mg/kg) followed MOR. Full MOR --> NTX-appropriate responding was dependent on the pretreatment dose and time of MOR, with full effects observed only when MOR (10 mg/kg) was given 3 to 4 h before NTX. While subjects were maintained on either 20- or 40 mg/kg/day of MOR via osmotic pump, NTX produced full dose-dependent, MOR --> NTX-appropriate responding. When the MOR-filled pumps were removed, partial MOR --> NTX-appropriate responding occurred, peaking at 6 to 12 h. The physical withdrawal signs produced by NTX after acute or during chronic MOR exposure were of smaller magnitude compared with the ones that occurred during abrupt withdrawal from chronic MOR. A qualitatively unique "withdrawal" stimulus that is dose- and time-dependent appears to be the basis of this MOR --> NTX discrimination.  (+info)

Issues in the treatment of active tuberculosis in human immunodeficiency virus-infected patients. (8/10578)

Most HIV-infected patients with tuberculosis can be treated satisfactorily with standard regimens with expectations of good results. Treatment of tuberculosis in these patients has been complicated by the introduction of HAART, which relies on drugs that interfere with the most potent class of antituberculous medications. Rifampin-free regimens or regimens that employ rifabutin may be acceptable strategies for patients who are receiving protease inhibitors, although these regimens have not been rigorously evaluated in patients with AIDS. At present, there is good reason to believe that a 6-month course of a rifabutin-containing regimen or a 9-12-month course of a regimen of streptomycin, isoniazid, and pyrazinamide should be adequate therapy for most patients with drug-susceptible disease. As the treatment of HIV infection with antiretroviral agents evolves, the treatment of tuberculosis in patients with AIDS is likely to evolve as well. This will require careful coordination of antituberculosis and antiretroviral therapies.  (+info)

Background: Vinpocetine, a semi-synthetic derivative of vincamine, is a popular dietary supplement used for the treatment of several central nervous system related disorders. Despite its wide use, no pharmacokinetic drug interaction studies are reported in the literature. Due to increasing use of dietary supplements in combination with conventional drugs, the risk of adverse effects is on the rise. As a preliminary step to predict a possibility of drug interaction during concomitant use of vinpocetine and conventional drugs, this study was carried out to evaluate the effects of vinpocetine on three main regulators of pharmacokinetic drug interactions namely, cytochromes P450 (CYPs), P-glycoprotein (P-gp), and Pregnane X receptor (PXR). Methods: Inhibition of CYPs was evaluated by employing recombinant enzymes. The inhibition of P-gp was determined by calcein-AM uptake method in transfected and wild type MDCKII cells. Modulation of PXR activity was monitored through a reporter gene assay in HepG2

Methods: All discharged patients in the Department of Oncology were collected from Jun to Dec in 2016 with the Hospital Information System of the Chinese peoples Liberation Army General Hospital. Drugs were screened for interactions by Micromedex solutions database. Descriptive statistics were generated and logistic regression was used to identify the associated factors. Results: Among 6578 eligible patients, 1979 potential drug interactions were found in 1830 patients (27.82%). The most common drug-drug interaction was cisplatin and furosemide. Erlotinib was most likely to interact with various non-anticancer drugs. Most interactions were classified as pharmacodynamics (71.60%), major severity (97.02%) and were supported by fair documentation evidence (86.21%). In multivariate ...
Second-generation antidepressants are not equivalent in their potential for pharmacokinetic drug interactions. Although interactions may be predictable in specific circumstances, use of an antidepressant with a more favorable drug-interaction profile may be justified.

Background: General consumers can now easily access drug information and quickly check for potential drug-drug interactions (PDDIs) through mobile health (mHealth) apps. With aging population in Canada, more people have chronic diseases and comorbidities leading to increasing numbers of medications. The use of mHealth apps for checking PDDIs can be helpful in ensuring patient safety and empowerment. Objective: The aim of this study was to review the characteristics and quality of publicly available mHealth apps that check for PDDIs. Methods: Apple App Store and Google Play were searched to identify apps with PDDI functionality. The apps general and feature characteristics were extracted. The Mobile App Rating Scale (MARS) was used to assess the quality. Results: A total of 23 apps were included for the review-12 from Apple App Store and 11 from Google Play. Only 5 of these were paid apps, with an average price of $7.19 CAD. The mean MARS score was 3.23 out of 5 (interquartile range 1.34). The mean MARS

November 20, 2020 St Louis Park, MN The FDA has issued a new Draft Guidance for Industry Clinical Drug Interaction Studies With Combined Oral Contraceptives which can be found on the FDA website at: This document discusses the need for drug-drug interaction (DDI) studies with combined oral contraceptives (COCs) containing an estrogen and a progestin when used to prevent pregnancy. The FDA reports COCs are highly effective in preventing pregnancy when used correctly. Unfortunately, interactions between COCs and other drugs may increase pregnancy risk or compromise patient safety by changing estrogen or progestin metabolism. For example, this guidance states increased estrogen and/or progestin levels can increase the risk of blood clots in veins which is a rare but serious adverse event. Women of childbearing age often use COCs and other ...

Adverse Drug Interactions: A Handbook for Prescribers assists clinicians by providing key information on potential adverse effects that can result from prescribing two or more drugs for simultaneous use.. Interactions that are likely to give rise to life-threatening conditions, and which must therefore be completely avoided, are clearly highlighted. Less threatening but nonetheless important interactions necessitating practical measures, such as frequent monitoring and advice to patients, are also discussed.. Presented in a user-friendly format, the book is organised by drug class and provides a brief summary of the mechanism underlying a particular interaction, alternative drugs lacking the same reactions that may be considered, and instructions for monitoring patients when adverse effects occur.. All interactions listed in the previous edition have been reviewed and updated using the latest information available. The clinical reality of the widespread use of potent medicines, whether ...

Our review of 92 papers and interviews with ten domain experts provides a preliminary catalog of the types of information that are needed to interpret the importance of a PDDI. Although basic information on the drugs involved and the nature of the potential interaction are obvious starting points, more detail is needed to interpret the clinical importance of a PDDI. Contextual information, such as patient-specific risk factors and the likelihood of occurrence of a serious adverse event, is critical to guide useful recommendations. The quality, strength, relevance, and source of the evidence about an interaction matter as well: evidence from large clinical trials involving patients may be given more credence than in vitro experiments or data from animal studies.. Although many similar themes were identified both in the reviewed literature and in our interviews, the latter provided valuable insight into the process of interpreting evidence for PDDIs (Fig. 2). Experts described personalized and ...
IVPhD Pharmacology. Department of Pharmacology, University of KwaZulu-Natal, Durban To the Editor: It has been estimated that globally about 38.6 million people were infected with HIV by 2005,1 with about 5 million of them living in South Africa (SA). The World Health Organization estimated that 4.7 million people living in sub-Saharan Africa urgently needed antiretroviral therapy (ART). In that year SA implemented prescribed minimum benefits (PMBs) for HIV/AIDS in the private health care sector.2 Despite the increased availability and affordability of ART in SA, only 60 000 people were receiving ART through medical aid schemes by mid-2005.3 Antiretrovirals (ARVs) have transformed HIV/AIDS into a chronic disorder that can be managed effectively. The right of all HIVinfected adults and children to receive standard care is endorsed by the SA HIV Clinicians Society (SAHIVCS),4 with ART guidelines recommending different combinations. The rapid approval of new drugs resulted in an increased risk of ...

As death approaches, patients are at their most frail, but an increasing symptom burden often necessitates an increase in medications, putting them at higher risk for drug-drug interactions.To assess the potential for drug-drug interactions in routine prescribing at the end of life.An Australian retrospective multicentre case-note review of 266 consecutive adult patients who were referred to specialist palliative care, with data available on 166. Medications used in the last 2 weeks of life were screened for potential interactions using the Stockleys Drug Interactions software.The mean number of medications prescribed was 10.8, median 9 (IQR 6-14); all patients received at least one medication. In this study, 72% of patients were at risk of 1 or more potential drug-drug interaction. The mean number of potential interactions was 4.4, with a median of 2.5 (IQR 0-7) per patient. There were only 4/166 (2.4%) prescribed medications with an associated clinical record of an adverse drug ...

Short-acting secretagogues. Nateglinide, which is metabolized by CYP2C9 (70%) and CYP3A4 (30%), could be affected by strong inhibitors/inducers of CYP2C9, but significant drug-drug interactions have not been reported. Repaglinide is metabolized by the CYP3A4 and CYP2C8 isozyme systems and then extensively glucuronidated. A serious drug-drug interaction may occur with gemfibrozil, which is used for triglyceride lowering. This is likely caused by gemfibrozils inhibition of CYP2C8 and glucuronidation. In vivo, gemfibrozil increases the total exposure of repaglinide eightfold.21 Several reports of severe, prolonged hypoglycemia have been documented with the combination.22 Strong inhibitors of CYP3A4, such as azole antifungal agents and erythromycin derivatives, may also enhance the hypoglycemic effect of repaglinide. Drugs that are inducers of CYP2C8/3A4 may reduce the efficacy of repaglinide, and a higher dose of repaglinide may be necessary23 (Table 2).. The main drug-disease interaction of ...

Table 18b. Drug Interactions Between Non-Nucleoside Reverse Transcriptase Inhibitors and Other Drugs. This table provides information relating to PK interactions between NNRTIs and non-ARV drugs. For interactions between ARV agents and for dosing recommendations, refer to Tables 18c, 19a, and 19b. Recommendations for managing a particular drug interaction may differ depending on whether a new ARV drug is being initiated in a patient on a stable concomitant medication or if a new concomitant medication is being initiated in a patient on a stable ARV regimen. The magnitude and significance of drug interactions are difficult to predict when several drugs with competing metabolic pathways are prescribed concomitantly.

REDWOOD CITY, Calif., Feb. 13, 2017 (GLOBE NEWSWIRE) -- Relypsa, Inc., a Vifor Pharma company, today announced that results of drug-drug interaction studies of Veltassa® (patiromer) for oral suspension were published online by the Journal of Cardiovascular Pharmacology and Therapeutics. Results from 12 individual Phase 1 studies in healthy volunteers of 12 oral medications showed there were no clinically meaningful or statistically significant interactions between Veltassa and the 12 oral medications when taken at least three hours apart. Relypsa previously announced these findings in January 2016. These Phase 1 studies in healthy volunteers were rigorously designed to maximize the probability of identifying drug-drug interactions with Veltassa if they were to occur, said Lawrence J. Lesko, Ph.D., lead author of the publication, and Professor and Director of the Center for Pharmacometrics and Systems Pharmacology at the University of Florida College of Pharmacy in Orlando, Fla.

Outcome factors were potential drug-disease and drug-drug interactions identified by using particular criteria from various sources, as well as self-reported non-prescription and prescription drug use. Explicit criteria for 70 potential drug-drug interactions developed by geriatric experts and reactions found to be a cause for drug-related hospitalizations were used.. The findings showed that 34% of patients (34.1%) had at least one interaction, while 25.1% had at least one drug-drug interaction. Also, 10.7% of patients who had a drug-drug interaction involved a non-prescription drug. Sixteen percent of patients had a potential drug-disease interaction, with at least 37% of those reactions involving a non-prescription drug.. Non-steroidal anti-inflammatory drugs (NSAIDs) and anti-hypertensive agents were the most common drug-drug interaction. Aspirin/NSAID use in patients with a history of peptic ulcer disease without the use of gastro-protection (4.3%) was the most common drug-disease ...

While there has been some indication that csDMARDs comedication with TNFi is of no additional value in AS,16 ,18-21 this is not a question that has been extensively studied. Keeping in mind that the effect of comedication is of unequivocal importance in RA and that there also is some evidence supporting a benefit in PsA,5 ,7 we set out to study this question in AS and uSpA. When adjusting for potential confounders we found a statistically significant beneficial effect of csDMARD comedication on TNFi drug survival both in AS and in uSpA. The effect was more pronounced in AS (HR 0.71) compared with uSpA (HR 0.82), and present both for MTX and other csDMARDs in AS, while in the uSpA group we could only find an effect for MTX. Due to missing data we chose to adjust for measures of disease activity in separate models (table 3), in which the association with csDMARD comedication remained stable or tended to be strengthened.. Although the available data are limited, the efficacy of csDMARDs in axial ...

Metabolism is the enzymatic modification of drugs and other xenobiotics, usually to increase clearance. It is a determinant of oral bioavailability, clearance, and half-life in vivo. Metabolism occurs predominantly in the liver and may also occur in the intestine or other organs.. Evaluation of an NMEs drug-drug interaction potential is an integral part of drug development and regulatory review prior to market approval. Many metabolic routes of elimination, including most of those occurring through the cytochrome P450 family of enzymes, can be inhibited or induced by concomitant drug treatment. An NME must be characterized both in terms of the enzymatic pathway(s) by which it is metabolized and in terms of the effects it may have on the metabolism of other drugs. If positive, the latter is an example of a pharmacokinetic drug-drug interaction.. Observed changes arising from metabolic drug-drug interactions can be substantial - an order of magnitude or more decrease or increase in the blood or ...
Although many of the clinically significant drug interactions of the anti-human immunodeficiency virus (HIV) protease inhibitors (PIs) can be explained by their propensity to inactivate CYP3A enzymes, paradoxically these drugs cause (or lack) interactions with CYP3A substrates that cannot be explained by this mechanism (e.g., alprazolam). To better understand these paradoxical interactions (or lack thereof), we determined the cytochromes P450 and transporters induced by various concentrations (0-25 μM) of two PIs, ritonavir and nelfinavir, and rifampin (positive control) in primary human hepatocytes. At 10 μM, ritonavir and nelfinavir suppressed CYP3A4 activity but induced its transcripts and protein expression (19- and 12- and 12- and 6-fold, respectively; a ,2-fold change over control was interpreted as induction). At 10 μM, rifampin induced CYP3A4 transcripts, CYP3A protein, and activity by 23-, 12-, and 13-fold, respectively. The induction by rifampin of CYP3A activity was significantly ...
TY - JOUR. T1 - Combination therapy in epilepsy. T2 - When and what to use. AU - Kwan, Patrick. AU - Brodie, Martin J.. PY - 2006/10/23. Y1 - 2006/10/23. N2 - After being regarded as a last resort for over two decades, the role of combination therapy as a treatment strategy for epilepsy is undergoing reevaluation. This is a result of the growing appreciation that all seizures cannot be controlled by monotherapy in a substantial proportion of patients, and of the development of a range of modern antiepileptic drugs (AEDs), some of which are better tolerated and less prone to complex pharmacokinetic drug interactions than their older counterparts. Robust evidence to guide clinicians on when and how to combine AEDs is lacking, and current practice recommendations are largely empirical. Monotherapy should remain the treatment of choice for newly diagnosed epilepsy. A combination of two AEDs can be considered after failure, resulting from lack of efficacy, of one or two different monotherapy ...

The aim of the study was to investigate exposure levels of organochlorine pesticides (OCPs) in mothers milk and in selected staple foods. The study also aimed to evaluated effects of 1,1,1-trochloro-2-bis-(4-chlorophenyl)ethane (DDT) on paracetamol half-life in highly exposed and least exposed breast-feeding mothers as a way of investigating possible drug interaction. This was an experimental study where milk and food samples from Esigodini, Harare, Kadoma Kariba Nyanga and Mudzi were collected and analysed for OCPs levels using GC-ECD. Evaluation of induction of the hepatic cytochrome P450 enzymes by DDT was carried out by pre-treatment of female rats with a single intraperitoneal dose of DDT (0.3 mg/g) body weight. Cytochrome P450 enzyme was quantified by potassium phosphate buffering the microsomal fraction followed by spectral determination of the reduction of cytochrome P450. Blood samples from selected mothers in areas showing results of higher exposure levels to DDT and selected mothers ...
Introduction: Prescribing drugs is the most common intervention in healthcare. People with intellectual disabilities are likely to be prescribed more drugs than other individuals as they experience greater levels of ill‐health. Most available evidence focuses on psychotropic drug prescribing, with an absence of population‐level research on complete prescribing occurrences and potential drug-drug interactions in persons with intellectual disabilities. Methods: A total population sampling approach identified all individuals with intellectual disabilities known to services in Jersey ‐ 217 individuals participated. Prescribed drug data were categorised according to the Anatomical Therapeutic Chemical (ATC) classification system and potential drug-drug interactions were graded according to severity using Stockleys Drug Interaction Checker. Results: As our analysis is ongoing, we cannot outline firm conclusions at this stage. Nevertheless, our results will; (1) outline the pattern and ...
The first part of this research provides a realistic mathematical physiological model of the liver to predict drug drug interactions (DDIs). The model describes the geometry of a lobule (liver unit) and integrates the exchange processes, diffusion and active transport, between the hepatocytes and the blood and possible drug-drug interactions such as; reversible inhibition, mechanistic based inhibition (MBI) and enzyme induction. The liver model is subsequently integrated into a PBPK model with 7 compartments (artery blood, venous blood, gut, liver, kidney, lung, rest of the body). To assess the efficiency of the model to predict DDIs, 77 clinical DDI studies were compared to the model. These 77 clinical studies represent 5 victim drugs (midazolam, simvastatin, triazolam, cerivastatin and nifedipine) and 30 perpetrator drugs. The reversible inhibition, MBI and induction parameters for the majority of the perpetrators were estimated with in vitro experiments and adjusted for the human liver size. ...
The JAK2/STAT signaling pathway mediates cytokine receptor signals that are involved in cell growth, survival and homeostasis. JAK2 is a member of the Janus kinase (JAK) family and aberrant JAK2/STAT is involved with various diseases, making the pathway a therapeutic target. The similarity between the ATP binding site of protein kinases has made development of specific inhibitors difficult. Current JAK2 inhibitors are not selective and produce unwanted side effects. It is thought that increasing selectivity of kinase inhibitors may reduce the side effects seen with current treatment options. Thus, there is a great need for a selective JAK inhibitor. In this study, we identified a JAK2 specific inhibitor. We first identified key pharmacological interactions in the JAK2 binding site by analyzing known JAK2 inhibitors. Then, we performed structure-based virtual screening and filtered compounds based on their pharmacological interactions and identified compound NSC13626 as a potential JAK2 inhibitor.
All pharmaceutical companies are required to assess pharmacokinetic drug-drug interactions (DDIs) of new chemical entities (NCEs) and mathematical prediction helps to select the best NCE candidate with regard to adverse effects resulting from a DDI before any costly clinical studies. Most current models assume that the liver is a homogeneous organ where the majority of the metabolism occurs. However, the circulatory system of the liver has a complex hierarchical geometry which distributes xenobiotics throughout the organ. Nevertheless, the lobule (liver unit), located at the end of each branch, is composed of many sinusoids where the blood flow can vary and therefore creates heterogeneity (e.g. drug concentration, enzyme level). A liver model was constructed by describing the geometry of a lobule, where the blood velocity increases toward the central vein, and by modeling the exchange mechanisms between the blood and hepatocytes. Moreover, the three major DDI mechanisms of metabolic enzymes; ...
TY - JOUR. T1 - Evaluating the disposition of a mixed aldehyde oxidase/cytochrome P450 substrate in rats with attenuated P450 activity. AU - Crouch, Rachel D.. AU - Morrison, Ryan D.. AU - Byers, Frank W.. AU - Lindsley, Craig W.. AU - Emmitte, Kyle Allen. AU - Daniels, J. Scott. PY - 2016/8/1. Y1 - 2016/8/1. N2 - Marketed drugs cleared by aldehyde oxidase (AO) are few, with no known clinically relevant pharmacokinetic drug interactions associated with AO inhibition, whereas cytochrome P450 (P450) inhibition or induction mediates a number of clinical drug interactions. Little attention has been given to the consequences of coadministering a P450 inhibitor with a compound metabolized by both AO and P450. Upon discovering that VU0409106 (1) was metabolized by AO (to M1) and P450 enzymes (to M4-M6), we sought to evaluate the in vivo disposition of 1 and its metabolites in rats with attenuated P450 activity. Male rats were orally pretreated with the pan-P450 inactivator, 1-aminobenzotriazole (ABT), ...
Objectives Development of direct acting antivirals (DAA) offers new benefits for patients with chronic hepatitis C. The combination of these drugs with antiretroviral treatment (cART) is a real challenge in HIV/HCV coinfected patients. The aim of this study was to describe potential drug-drug interactions between DAAs and antiretroviral drugs in a cohort of HIV/HCV coinfected patients. Methods Cross-sectional study of all HIV/HCV coinfected patients attending at least one visit in 2012 in the multicenter French DatAIDS cohort. A simulation of drug-drug interactions between antiretroviral treatment and DAAs available in 2015 was performed. Results Of 16,634 HIV-infected patients, 2,511 had detectable anti-HCV antibodies, of whom 1,196 had a detectable HCV-RNA and were not receiving HCV treatment at the time of analysis. 97.1% of these patients were receiving cART and 81.2% had a plasma HIV RNA |50 copies/mL. cART included combinations of nucleoside reverse transcriptase inhibitors with a boosted
Results Among 371 PsA patients being treated with TNFi, 145 received csDMARD co-medication; 58/118 with etanercept, 48/106 with adalimumab, 21/47 with certolizumab and 18/47 with golimumab, respectively. Mean (SD) age was 54.0 (11.5) years, disease duration 13.1 (9.1) years, years of education 12.9 (3.4), body mass index (BMI) 27.1 (4.3) kg/m2, baseline DAS28 4.1 (1.4), 45.7% were female. Baseline characteristics were similar for patients with and without co-medication, except for a higher percentage of first time TNFi users (67.6%) compared to previous TNFi users (32.4%) in the co-medication group, p=0.001. Drug survival of TNFi was similar for patients receiving versus not receiving concomitant csDMARDs (log rank test p=0,181, figure). In the Cox regression analysis identified predictors for TNFi discontinuation were previous use of TNFi (HR 1.68, 95% CI 1.25-2.26, p,0.001) and TNFi type (p,0.001). Separate analyses for first time TNFi users did not change the primary outcome. Separate ...
Summary Proton pump inhibitors or PPIs for short are drugs that inhibit proton or acid production by your stomach. They do this specifically by blocking an ATPase pump that pumps acidic protons out of cells in exchange for bringing potassium into the cell. Reduction of stomach acid is useful in treating acid-mediated disorders like peptic ulcers or acid reflux. Side effects of using PPIs include increased fracture risk as a result of decreased GI calcium absorption, and increased susceptibility to infections. Lastly, PPIs inhibit CYP or cytochrome P450 enzymes, leading to a significant drug interaction risk. Key Points - Proton Pump InhibitorsDrug Names (-prazole)Omeprazole, EsomeprazoleLansoprazole, dexlansoprazolePantoprazoleMechanismProton Pump Inhibitor (PPI) Irreversibly inhibit H+/K+ ATPase in stomach parietal cellsgreatly reduces acid secretionProton secretion is the final common pathway of gastric acid secretion from parietal cells, which are stimulated by acetylcholine, histamine,

Entecavir (ETV) is one of the most potent agents for the treatment of the hepatitis B viral infection. The drug is principally eliminated by the kidney. The goal of this study was to investigate the potential of ETV to interact in vitro with the renal SLC transporters hOAT1, hOCT2, hCNT2 and hCNT3. Potential drug-drug interactions of ETV at the renal transporters with antiviral drugs known to be excreted by the kidney (adefovir, tenofovir, cidofovir) as well as transporter-dependent cytotoxicity were also examined. Interactions with the selected transporters along with cytotoxicity were studied in several transiently-transfected cellular models using specific substrates and inhibitors. ETV was found to be both a substrate and inhibitor of hOAT1 (IC50 = 175.3 µM), hCNT2 (IC50 = 241.9 µM) and hCNT3 (IC50 = 278.4 µM) transporters, although it interacted with the transporters with relatively low affinities. ETV inhibited the cellular uptake of adefovir, tenofovir and cidofovir by hOAT1; however,

Introduction: Integrating HIV and tuberculosis (TB) treatment can reduce mortality substantially. Practical barriers to treatment integration still exist and include safety concerns related to concomitant drug use because of drug interactions and additive toxicities. Altered therapeutic concentrations may influence the chances of treatment success or toxicity. Areas covered: The available data on drug-drug interactions between the rifamycin class of anti-mycobacterials and the non-nucleoside reverse transcriptase inhibitor and the protease inhibitor classes of antiretrovirals are discussed with recommendations for integrated use. Additive drug toxicities, the impact of immune reconstitution inflammatory syndrome (IRIS) and the latest data on survival benefits of integrating treatment are elucidated. Expert opinion: Deferring treatment of HIV to avoid drug interactions with TB treatment or the occurrence of IRIS is not necessary. In the integrated management of TB-HIV co-infection, rational drug

(
  • Unlike furanocoumarin-rich grapefruit juice which could primarily precipitate drug interactions by strong inhibition of cytochrome P450 3A4 isoenzyme and P-glycoprotein and thus cause deadly outcomes due to co-ingestion with some medications, other fruit juices did not precipitate severely detrimental food-drug interaction despite of sporadic case reports.

  • Iron supplements interact with a long list of drugs used to treat a variety of conditions. (
  • While many patients are aware of prescription drug interactions, supplements may also interact with prescription and non-prescription medicines. (
  • BPA, a crucial component in plastics production, has shown to interact with various anti-cancer therapeutics, which can result in drug resistance and reduced effectiveness. (
  • Calcium can interfere with the absorption of these drugs and make them less effective. (
  • Most of the important drug interactions result from a change in the absorption, metabolism, or elimination of a drug. (
  • Most drug interactions that are due to altered absorption occur in the intestine. (
  • There are various ways that the absorption of drugs can be reduced. (
  • Drug absorption also can be affected if the drug's ability to dissolve (solubility) is changed by another drug or if a substance (for example, food) binds to the drug and prevents its absorption. (
  • Solubility and absorption REDUCED by other drugs that alkalinise (relatively) the stomach - i.e. (
  • The absorption of the pro-drug dabigatran etexilate is mediated by P-glycoprotein (P-gp). (
  • P-gp inhibitors can increase the absorption of dabigatran etexilate, ultimately increasing both AUC and Cmax of dabigatran, the active drug. (
  • Conversely, P-gp inducers can reduce the absorption of dabigatran etexilate, ultimately decreasing AUC and Cmax of dabigatran, the active drug. (
  • Calcium, magnesium and aluminum found in food supplements or antacids bind with the antibiotic TCN, resulting in decreased absorption and antibiotic effect of the drug. (
  • Foods may alter the effects of drugs by interfering with pharmacokinetic processes, such as absorption and elimination. (
  • This means that grapefruit juice has the potential to enhance the absorption of these certain prescription drugs. (
  • Bulk laxatives such as psyllium, magnesium-based antacids, and lactulose products may reduce the absorption of other drugs if administered at the same time. (
  • There has been increasing focus on the role of the drug transporter P-glycoprotein (Pgp) in drug absorption into the brain. (
  • While the tissue distribution of Pgp influences the effect of psychotropics and the interaction potential for drugs such as risperidone, nortriptyline, and citalopram at the interface between the blood and central nervous system (CNS), Pgp is also found in other areas of the body such as the intestines, which are a major site for drug absorption into the body. (
  • It is thought that some interactions, mainly seen with the antiepileptic drugs (AEDs), previously assumed to be a result of CYP450 alterations, instead may actually be mediated by the modulation of the Pgp activity at the point of drug absorption or distribution. (
  • Various herbs can affect drug absorption and metabolism, for example, which can in turn increase or decrease the effectiveness and toxicity of various medicines. (
  • Low drug concentrations can also be caused when the fruit suppresses drug absorption from the intestine. (
  • The effect of grapefruit juice with regard to drug absorption was originally discovered in 1989. (
  • In some cases, the cause of thyroid medication not working is reduced absorption because of these interactions. (
  • Even so, if you look at the various tables, what you will see over-and-over is that most of these drugs, regardless of the class they are in, deplete key nutrients like the B, C and D vitamins, as well as Co-Q 10, and also wipes out (or blocks absorption of) various essential minerals. (
  • Cholesterol -lowering drugs including cholestyramine and colestipol interfere with the absorption of iron. (
  • Conversely, iron decreases the absorption of some drugs including antibiotics like quinolones and tetracyclines and ACE inhibitors that treat high BP. (
  • There are quite a few drugs that interfere with the absorption of thyroid-replacement therapy, for example. (
  • Some drugs are able to reduce or increase the metabolism of other drugs by the liver or their elimination by the kidney. (
  • Metabolism of drugs is the process through which the body converts (alters or modifies) drugs into forms that are more or less active (for example, by converting drugs that are given in inactive forms into their active forms that actually produce the desired effect) or that are easier for the body to eliminate through the kidneys. (
  • Most drug metabolism takes place in the liver, but other organs also may play a role (for example, the kidneys, intestine, etc. (
  • The cytochrome P450 enzymes are a group of enzymes in the liver that are responsible for the metabolism of most drugs. (
  • The contribution of gastric alcohol dehydrogenase to the first pass metabolism of ethanol and alcohol-drug interactions is now recognized. (
  • The elderly have less cytochrome P-450 (CYP450), an enzyme involved in drug metabolism, which leads to the change in drug metabolism being less pronounced. (
  • Such factors include the potency and concentration of the drugs involved, the therapeutic index balanced between efficacy and toxicity, the presence of active metabolites, and the extent of the metabolism of the substrate drug. (
  • Unlike inhibition that occurs immediately when drug binds to substrate, inducers responsible for increasing hepatic metabolism can require days or weeks to produce the most significant effect and therefore may not substantially impact treatment decisions in an acute care environment. (
  • Compromising its metabolism lowers concentrations of the active drug, reducing its therapeutic effect, and risking therapeutic failure. (
  • The primary purpose for drug metabolism is to detoxify, inactivate, solubilize and eliminate these drugs. (
  • verification needed] As a result, the amount of the drug in its original form that reaches systemic circulation is reduced due to this first-pass metabolism. (
  • Drug interactions with antiretrovirals are commonly caused by the inhibition or induction of hepatic drug metabolism. (
  • Test your knowledge about taking acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs). (
  • On the advice of an expert panel that reviewed new information about nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and naproxen and their risks, the Food and Drug Administration in 2015 strengthened its warnings of heart attack and stroke risk increase even with short-term use, and warned the risk may begin within a few weeks of starting to take an NSAID. (
  • But, after analyzing common combinations of pills-which include statins, nonsteroidal anti-inflammatory drugs (NSAIDs), antiplatelet agents such as aspirin and clopidogrel, and anticoagulants like warfarin-the researchers found that the number of older people at risk of a serious drug-drug interaction nearly doubled over five years-from 8.4 to 15.1 percent. (
  • Nonsteroidal Anti-inflammatory Drugs (NSAIDs) are among the most popular drugs in the pharmacy. (
  • Patients who drink alcohol while taking nonsteroidal anti-inflammatory drugs (NSAIDs) increases the risk of stomach bleeding. (
  • St. John's wort can affect the way your body processes prescription and over-the-counter drugs. (
  • Other serious alcohol interactions are associated with over-the-counter antihistamines and herbal remedies such as kava kava, St. John's wort, chamomile, valerian, and lavender. (
  • Clinical data are limited regarding drug interactions with inhaled zanamivir. (
  • Limited clinical data are available regarding drug interactions with oral oseltamivir. (
  • Few published data from clinical trials are available concerning the safety or efficacy of using combinations of different classes of influenza antiviral drugs. (
  • The drug and drug interactions databases in UpToDate add another level of knowledge to clinical practice and help improve the quality and safety of care. (
  • Drug-food interactions are a significant problem in clinical practice. (
  • The population impact of this preventable drug-drug interaction can be considered in the context of the high frequency of clarithromycin and statin co-prescription (rosuvastatin, or Crestor, was the second most commonly dispensed drug in Canada in 2010)," writes Dr. Amit Garg, a nephrologist in the Department of Medicine, Western University, and scientist at the Lawson Health Research Institute and Institute for Clinical Evaluative Sciences Western, London, Ont. (
  • The experiment began with thousands of patient files, millions of prescription orders, billions of clinical measurements and a single question: Could big data be used to discover deadly drug combinations? (
  • The first published clinical report on grapefruit drug interactions was in 1991 in The Lancet entitled "Interactions of Citrus Juices with Felodipine and Nifedipine. (
  • This is a clinical trial to characterize drug interactions between silimarine and the protease inhibitor darunavir/ritonavir. (
  • Twenty-two juice-drug combinations showed potential clinical relevance. (
  • However, another study questions the clinical relevancy of in vivo pharmacokinetic interaction between cranberry juice and midazolam. (
  • With respect to pharmacodynamic aspects, while the debate continues on the issue of an interaction between warfarin and cranberry juice, the summation of the pharmacodynamics data obtained in patients and healthy subjects from different prospectively designed and controlled clinical trials does not provide overwhelming support for the existence of a pharmacodynamic drug interaction for normal cranberry juice ingestion. (
  • Among 46 finally included RCTs, six RCTs simply addressed pharmacodynamic interactions and 33 RCTs studied pharmacokinetic interactions, whereas seven RCTs investigated both pharmacokinetic and pharmacodynamic interactions. (
  • And some combinations of drugs can be dangerous. (
  • A 2008 study in the Journal of the American Medical Association showed that about 2.2 million people age 57 to 85 were taking potentially dangerous combinations of drugs. (
  • But new worries have emerged that suggest a growing number of older Americans are taking drug combinations that put them at risk for a harmful or even deadly drug interaction. (
  • The research team spotted 93 potentially dangerous combinations, based on the 40 most commonly used drugs and supplements. (
  • However, once drugs prescribed for other conditions and over-the-counter (OTC) supplements are added, the combinations may result in significant harm. (
  • Two years later, the results are in: The team has identified four drug combinations associated with a heart condition that can lead to a potentially fatal arrhythmia. (
  • To find the potentially risky combinations, the Tribune enlisted the help of scientists at Columbia, who used sophisticated algorithms to analyze a massive government database of drug complaints for signs of the heart condition. (
  • The team next turned to Columbia cellular researchers, who tested one of the drug combinations on individual cells. (
  • However, pharmacokinetics and pharmacodynamics interactions could be perceived in drug combinations, so in this short review we tried to shed light on the potential drug interactions of medicinal cannabis. (
  • The amount of information on drug-drug interactions is overwhelming, so health systems have implemented the use of computer software to assist in the detection of these problematic combinations. (
  • Gov. Bruce Rauner on Monday asked state agencies to study ways to improve accountability at pharmacies following a Tribune investigation on local drugstores' high failure rate in advising their customers of bad drug combinations. (
  • This study examined the interactions of various drugs used to treat HIV infection in order to design larger studies of possible combinations for people who continue to have high viral levels despite combination therapy. (
  • According to the researchers, at least one in 25 older adults take multiple drugs in combinations that can produce a harmful drug interaction. (
  • This is known as an adverse drug-drug interaction and it is very expensive and time-consuming to screen a new drug candidate with all the possible combinations of drugs that a patient may be taking. (
  • Another recent study showed that a triple-combination antiviral drug (TCAD) regimen consisting of oral doses of amantadine, oseltamivir, and ribavirin, had similar pharmacokinetics in healthy volunteers to each individual antiviral during monotherapy following a single oral dose, and that TCAD was administered safely in immunocompromised patients (Seo, 2013).
