The circadian dimension of precision medicine

Research across more than a hundred drug studies shows that for 75% of medications, efficacy or toxicity depends on dosing time. From chemotherapy to blood pressure drugs to vaccines, circadian science is revealing a hidden variable in medicine — and it could change how we prevent, diagnose, and treat disease.

Circadian medicine asks not only what to prescribe, but when. The application of circadian biology to clinical considerations is the foundation of an emerging field called circadian medicine, which will properly encompass the new dimension of time.
