Ingestion-time differences in the pharmacodynamics of dual-combination hypertension therapies: Systematic review and meta-analysis of published human trials

The pharmacodynamics of hypertension medications can be significantly affected by circadian rhythms in the biological mechanisms of the 24 h blood pressure (BP) pattern. Hypertension guidelines fail to recommend the time of day when patients, including those who require treatment with multiple medications, are to ingest BP-lowering therapy. We conducted a systematic review of published prospective trials that investigated hypertension medications for ingestion-time differences in BP-lowering, safety, patient adherence, and markers of target organ pathology. Among the search-retried 155 trials, 17 published between 1991 and 2020 totaling 1,508 hypertensive participants concerned the differential ingestion-time dependent effects of 14 unique dual-combination therapies. All but one (94.1%) of the trials, involving 98.5% of the total number of investigated individuals, reported clinically and statistically significant benefits - including enhanced reduction of asleep BP without induction of sleep-time hypotension, reduced prevalence of BP non-dipping, decreased adverse effects, improved kidney function, and reduced cardiac pathology - when dual-combination hypertension medications were ingested at-bedtime/evening rather than upon-waking/morning. A systematic and comprehensive review of the literature published in the past three decades reveals no single dual-combination hypertension trial reported significantly better benefit of the still conventional, yet unjustified by medical evidence, upon-waking/morning hypertension treatment scheme.

Ingestion-time differences in the pharmacodynamics of hypertension medications: Systematic review of human chronopharmacology trials

Pharmacokinetics of hypertension medications is significantly affected by circadian rhythms that influence absorption, distribution, metabolism and elimination. Furthermore, their pharmacodynamics is affected by ingestion-time differences in kinetics and circadian rhythms comprising the biological mechanism of the 24 h blood pressure (BP) pattern. However, hypertension guidelines do not recommend the time to treat patients with medications. We conducted a systematic review of published evidence regarding ingestion-time differences of hypertension medications and their combinations on ambulatory BP-lowering, safety, and markers of target organ pathology. Some 153 trials published between 1976 and 2020, totaling 23,869 hypertensive individuals, evaluated 37 different single and 14 dual-fixed combination therapies. The vast (83.7%) majority of the trials report clinically and statistically significant benefits - including enhanced reduction of asleep BP without inducing sleep-time hypotension, reduced prevalence of the higher cardiovascular disease risk BP non-dipping 24 h profile, decreased incidence of adverse effects, improved renal function, and reduced cardiac pathology - when hypertension medications are ingested at-bedtime/evening rather than upon-waking/morning. Non-substantiated treatment-time difference in effects by the small proportion (16.3%) of published trials is likely explained by deficiencies of study design and conduct. Systematic and comprehensive review of the literature published the past 45 years reveals no single study reported significantly better benefit of the still conventional, yet unjustified by medical evidence, upon-waking/morning hypertension treatment schedule.
