Filter by:There are currently no published studies addressing drug-drug interactions (DDI) between masculinizing hormone therapy (MHT) and pre-exposure prophylaxis (PrEP) among transgender men (TGM). This could lead to concerns and subsequent prioritizing MHT over PrEP among TGM. Because tenofovir alafenamide (TAF) can achieve higher intracellular tenofovir diphosphate (TFV-DP) levels with lower tenofovir plasma concentrations, it is promising that both plasma tenofovir (TFV) and intracellular TFV-DP levels might not be significantly affected by MHT. The current study aims to determine the pharmacokinetics (PK) DDI between MHT and daily PrEP among TGM.
Recent studies have showed that there were significant drug-drug interactions (DDI) from feminizing hormone therapy (FHT) towards emtricitabine/tenofovir disoproxil fumarate (F/TDF)-based pre-exposure prophylaxis (PrEP) among transgender women (TGW). New strategies for PrEP among TGW who use FHT are urgently needed. Because tenofovir alafenamide (TAF) can achieve higher intracellular TFV-DP levels with lower tenofovir plasma concentrations, it is promising that both plasma TFV and intracellular TFV-DP levels might not be significantly affected by FHT. The current study aims to determine the pharmacokinetics DDI between FHT and F/TAF-based PrEP among TGW.
This study is designed to formally evaluate the impact of famotidine, an H2R antagonist, on the pharmacokinetics of telaglenastat. This study will be conducted in up to 22 healthy volunteers, who meet all of the inclusion criteria and none of the exclusion criteria. The study is double-blinded, randomized 2-way crossover in design. Subjects will receive four 200 mg tablets of telaglenastat either in the presence or absence of 20 mg famotidine (H2R-antagonist) with a 4-day wash-out period in between each regimen.

The French Public Health strategy 2018-2022 aims to reduce inappropriate prescriptions, as potentially dangerous for individuals and collectively. The reduction of co-prescriptions at Risk of Drug Interactions (RoDI) could decrease the prevalence of iatrogenic diseases, and increase the persistence of treatments with a growing efficacy of treatments, in particular in elderly populations. A recent study conducted by our team showed that, in out-patient setting, 2.7% of co-prescriptions contains medications at RoDI of high degree of severity (object of a contra-indication or non-recommended). Up today, there is no French experience concerning the identification of RoDI among the prescriptions performed at the end of a hospitalisation. In France, the recent development of hospital data warehouses is a huge opportunity to develop a system that can identify efficiently co-prescriptions at RoDI and provide feedback directly to prescribers in order to reduce their frequency in hospital context. The primary objective of this study is to evaluate the capacity of a system, called PRoSIT system, to automatically identify the RoDI of high level of severity at hospital discharge.
This retrospective cohort study will include eligible patients that received a positive COVID-19 test and filled a new prescription for one of the repurposed medications (including hydroxychloroquine, chloroquine, with or without azithromycin) for the treatment of COVID-19 at a PrescribeWellness pharmacy. The study will use de-identified data collected from February 1, 2020 to start of study. The data set will include: repurposed medication name, strength, and dose; age (age limit set at 89 years old); gender; provider type; zip code (excludes 17 three-digit zip code tabulation areas that have a population of 20,000 or fewer persons); conditions; mortality; and a list of concomitant prescriptions.
This retrospective study aims to perform a medication risk stratification using drug claims data and to simulate the impact of the addition of various repurposed drugs on the Medication Risk Score (MRS) in a health insurance population. Our clinical tool would enable us to identify potential multi-drug interactions and potentially reduce the risk of adverse drug events (ADE) developing in these patients infected with COVID-19.

Patients with diabetes are three times more likely to develop erectile dysfunction (ED), and longer duration of diabetes is strongly associated with ED. The possibility of pharmacokinetic interactions may occur as the two drugs are metabolized by hepatic CYP3A4 and their co administration may affect their plasma concentrations. the aim of work is to investigate the effect of sildenafil a CYP3A4 substrate and inhibitor on the pharmacokinetics and safety of Saxagliptin, a CYP3A4 substrate Subjects and Methods: Eighteen healthy volunteers will be recruited in Sequential, single center study to determine pharmacokinetic parameters of Saxagliptin, and sildenafil,(AUC0→∞), (AUC0→t); Cmax; tmax; t½, k; ka) will be measured using validated LC-MS/MS method. Therapeutic doses will be given to volunteers as follows: Sildenafil 50 mg single dose on day 1, then washout period from day 2 till day 8. Saxagliptin 5 mg once/day will be given from day 9 till day 12, then on day 13 the two drugs will be co-administered. Blood samples (5ml) for pharmacokinetic analysis will be collected on days 1 and 13 for Sildenafil as well as on days 12 and 13 for Saxagliptin.
The purpose of this drug-drug interaction study is to investigate the impact of rifampicin on the pharmacokinetics of Dorzagliatin.
