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

Background: To survey the prevalence of potential drug-drug interactions (DDIs) between anticancer drugs and non-anticancer drugs and evaluate the risk factors associated with these drug-drug interactions in China. 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: https://www.fda.gov/regulatory-information/search-fda-guidance-documents/clinical-drug-interaction-studies-combined-oral-contraceptives-guidance-industry. 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 ...

The 60-and-over group took certain types of drugs significantly more often than younger people: drugs for gastrointestinal problems (63% versus 38%, P < 0.01), drugs for cardiovascular disease (55% versus 24%, P < 0.0001), anticoagulants or antiplatelets (18% versus 7%, P = 0.01), systemic hormonal agents (16% versus 5%, P = 0.01), musculoskeletal agents (24% versus 9%, P < 0.01), and narcotics or analgesics (39% versus 17%, P < 0.001). Anticonvulsant therapy was more frequent in the older group (16% versus 7%, P = 0.06), but older people took psychotropic agents at virtually the same rate as younger people (34% versus 30 ...

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 ...

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 ...

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

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,

At the contraluminal membrane there is evidence for one common transport system. At the luminal membrane, the transport of organic cations occurs by an electroneural Hf/organic cation system. E Contraluminal Transporters Fig. 7. Location of transporters for organic anions and cations in the renal proximal tubule (from Ullrich (1994)). Note: PAH is the organic anion p-aminohippuric acid. transporter, which transports sodium ions into the cell and hydrogen ions out (Fig. 7) (Somogyi, 1996). A key feature of a drug undergoing tubular secretion is that it will compete with another drug for secretion, thus competition for transport is competitive. These interactions have been categorized by Somogyi (1996); Table 7 summarizes their nature and sequelae.

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,

Title:Inflammation in Ischemic Stroke: Mechanisms, Consequences and Possible Drug Targets. VOLUME: 13 ISSUE: 8. Author(s):Muzamil Ahmad, Nawab J. Dar, Zubair S. Bhat, Aehtesham Hussain, Ayatullah Shah, Hao Liu and Steven H. Graham. Affiliation:Neuropharmacology Laboratory, Indian Institute of Integrative Medicine-CSIR, Sanat Nagar, Srinagar, 190005, India.. Keywords:Cerebral ischemia, cyclooxygenase-2, cytokines and chemokines, inflammation, microglia, middle cerebral artery occlusion, prostaglandin.. Abstract:Ischemic stroke is caused when blood flow to the brain is hampered, leading to instant deficiency of nutrients and oxygen required for normal brain functioning. Reperfusion can alleviate damage from stroke if performed immediately after the onset of ischemia however the efficacy of reperfusion is tempered by secondary injury mechanisms. This multifarious sequence of events leads to the commencement of deleterious cycles of inflammation, oxidant stress and apoptosis that finally culminate ...

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

Physicians who prescribe diuretics monitor people for significant or harmful side effects. If people do not tolerate the drug well, doctors may adjust the dosage accordingly. Physicians will also likely monitor the patients hearts, livers, and kidneys to make sure the medication is not negatively impacting any of the bodys systems. They may also quickly correct any problems that people experience, such as dehydration or electrolyte imbalances.. When people abuse hydrochlorothiazide, they frequently do not have the assistance of physicians who are monitoring their health. In addition, if people are abusing diuretics, they may not even tell their physicians they are using them. While diuretic abuse is rare, the side effects of the medication, combined with a lack of monitoring and a lack of knowledge of any potential drug interactions, may lead to significant and even life-threatening consequences.. Using diuretics, especially using them without prescriptions or without monitoring from ...
