Abstract

Chronopharmacology integrates chronobiology with pharmacotherapy to optimize drug administration according to the body’s circadian rhythms. Many physiological processes, including hormone secretion, cardiovascular function, metabolism, immune responses, and cellular proliferation, exhibit predictable daily variations that significantly influence drug pharmacokinetics, pharmacodynamics, efficacy, and toxicity. This review aims to summarize the fundamental principles of chronopharmacology, explain the mechanistic role of circadian rhythms and clock genes in drug response, and highlight its clinical relevance in modern pharmacotherapy. The core components of chronopharmacology—chronokinetics, chronesthesy, and chronotherapeutics—are discussed, emphasizing how biological timing affects drug absorption, distribution, metabolism, elimination, and tissue sensitivity. Clinical applications of chronotherapy across major disease conditions, including cardiovascular diseases, asthma, arthritis, gastrointestinal disorders, cancer, neurological disorders, and metabolic diseases, are reviewed, demonstrating that time-optimized drug administration can enhance therapeutic efficacy while reducing adverse effects. The review also addresses key advantages of chronopharmacology, such as improved disease control and personalized treatment strategies, alongside limitations including interindividual variability in circadian rhythms, complexity of dosing schedules, limited availability of chronotherapeutic formulations, and lifestyle-related circadian disruptions. In conclusion, chronopharmacology represents a promising approach within personalized medicine by aligning drug therapy with the body’s biological clock. With continued research, improved chronopharmaceutical formulations, and integration into clinical guidelines, chronopharmacology has the potential to significantly improve therapeutic outcomes and patient care.
