What was done
This narrative review summarizes drug-metabolizing enzymes and transporters that exhibit rhythmic diurnal expression across the liver, intestine, and kidney, along with the molecular mechanisms governing their circadian regulation.
What was found
The abstract reports no numerical data or specific effect sizes. It describes that diurnal expression of drug-processing proteins directly correlates with time-dependent drug exposure, pharmacokinetic variations, and circadian shifts in drug toxicity and therapeutic efficacy.
Why it matters
Understanding mechanism-based chronopharmacokinetics can guide the development of time-specific drug delivery systems to enhance therapeutic efficacy while minimizing adverse drug toxicity.
Limits
The paper is a narrative review without a systematic search protocol or quantitative data synthesis. Specific clinical outcomes, human translation parameters, and effect sizes are not reported in the abstract.
