Medication Timing: A Systematic Review of Clinical Research, Design, and Methodological Points
Medication timing is a critical yet often overlooked aspect of clinical practice. This systematic review synthesizes current evidence on the impact of medication timing on therapeutic outcomes, adherence, and safety. We conducted a comprehensive search of major databases up to 2025, identifying 45 relevant studies. Findings indicate that chronotherapy, or aligning drug administration with circadian rhythms, can significantly enhance efficacy and reduce adverse effects for certain medications, particularly those for cardiovascular and metabolic disorders. However, heterogeneity in study designs and outcome measures limits generalizability. We propose standardized reporting guidelines and highlight the need for personalized timing strategies based on individual chronotypes. This review underscores the importance of integrating medication timing into clinical decision-making and future research.
