Does adherence to antihypertensive medications improve blood pressure control and cardiovascular outcomes in hypertensive individuals?
This review highlights that prescribing effective antihypertensive therapy is insufficient without ensuring patient adherence to achieve optimal blood pressure control and cardiovascular outcomes.
Significant progress has been made in the management of hypertension (HTN) in the last 60 years. A large number of antihypertensive drugs (AHD) is available for effective control of elevated blood pressure (BP) that were also shown to be beneficial in improving all-cause mortality and cardiovascular morbidity in hypertensive individuals. Despite these successes, rates of BP control and outcomes in hypertensive patients remain suboptimal. Therefore, the availability of effective drug therapy itself appears to be insufficient to guarantee desirable results. Adherence to antihypertensive medications is a crucial mediator of favorable outcomes in treating HTN, and non-adherence, in turn, halts BP control. In this review, we will summarize the available evidence on health-related impacts of adherence to AHD, methods for the evaluation of adherence and potential interventions aimed to improve adherence in hypertensive individuals.
