Pharmacokinetics-based Chronotherapy

Abstract

Dosing time-dependency of pharmacokinetics (or chronopharmacokinetics) has been long recognized. Studies in recent years have revealed that daily rhythmicity in expression of drug-metabolizing enzymes and transporters (DMETs) are key factors determining chronopharmacokinetics. In this article, we briefly summarize current knowledge with respect to circadian mechanisms of DMETs and discuss how rhythmic DMETs are translated to drug chronoeffects. More importantly, we present our perspectives on pharmacokinetics-based chronotherapy.

Keywords: Chronopharmacokinetics; chronopharmacology; chronotherapy; circadian rhythms; drug transporters; drug-metabolizing enzymes.
