Characterization of Lysosomal Hydrolases and Transporters and Their Age‐Dependent Variability: Relevance to Drug Metabolism and Transport of Small Molecule and Biologic Drugs

Clinical Pharmacology &Therapeutics, EarlyView.
Lysosomes play a key role in the accumulation, catabolism, and transport of endogenous and exogenous metabolites and proteins and are involved in drug metabolism and prodrug activation. However, the protein abundance and interindividual variability of lysosomal drug‐metabolizing enzymes and transporters (DMETs) remain underexplored.

The Effect of Dicloxacillin Administration on Pharmacokinetics of Narrow Therapeutic Window Drugs: Phenytoin and Warfarin

Clinical Pharmacology &Therapeutics, EarlyView.
Dicloxacillin is a penicillinase‐resistant beta‐lactam antibiotic and potent activator of the Pregnane X receptor (PXR), known to induce CYP2C9, CYP2C19, and CYP3A4 activity. Clinical data suggest it reduces anticoagulation in warfarin‐treated patients and increases the risk of thromboembolic events.
