Dispensing of actionable pharmacogenetic drugs among adults receiving cardiovascular disease medications in the Northern Netherlands: A serial cross‐sectional study

Clinical Pharmacology &Therapeutics, EarlyView.
The extent of pharmacogenetic (PGx) drug dispensing among Dutch adults receiving medications for cardiovascular disease (CVD) is unknown. Using the University of Groningen IADB.nl pharmacy database, we performed a serial cross‐sectional study (2019–2023) to estimate the annual prevalence of PGx drug dispensing and annual rates of initiation.

Pharmacokinetics of Rifapentine and Desacetyl Rifapentine in Maternal Plasma and Breast Milk & Infant Cord Blood and Plasma: A Model‐Based Analysis of Mother–Infant Pairs for Tuberculosis Prevention

Clinical Pharmacology &Therapeutics, EarlyView.
IMPAACT 2001 (NCT02651259) evaluated the safety and pharmacokinetics (PK) of once‐weekly isoniazid and rifapentine in pregnant and postpartum women for tuberculosis prevention. Rifapentine (RPT) and desacetyl rifapentine (desRPT) PK data were collected in maternal plasma, breast milk, infant cord blood, and infant plasma.

Evaluating Vaginal Microbiome Effects on Antiretroviral Exposure in the Female Genital Tract Using Pharmacometric and Machine Learning Approaches

Clinical Pharmacology &Therapeutics, EarlyView.
Antiretroviral pre‐exposure prophylaxis (PrEP) is less effective in women than expected, partly because drug exposure within the female genital tract is variable and may be influenced by the vaginal microbiome. We developed an integrated pharmacometrics and machine learning framework to evaluate associations between vaginal microbiome composition and ...

The Impact of Common Medications on Male Fertility: An Updated Systematic Review

Andrology, EarlyView.
ABSTRACT Background Compared with those of cytotoxic treatments, the potential effects of common medications on the fertility of men trying to conceive currently or planning to conceive in the future are less well described. The use of common medications may modify the gonadotropic axis, spermatogenesis, and epididymal maturation or alter male ...

Plasma EC90 multiples are drug, target site and species specific—A physiologically based pharmacokinetic modelling example of nirmatrelvir central nervous system distribution

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Achieving minimum unbound drug concentration in plasma above in vitro EC90 is a common antiviral pharmacokinetic/pharmacodynamic (PK/PD) target. However, it often overlooks restricted distribution into target sites like the central nervous system (CNS), where a trough concentration above 1 × EC90 is needed.
