Negative impact of physician prescribed drug dosing schedule requirements on patient adherence to cardiovascular drugs.

Purpose: The aim of this study was to determine whether dosing schedule requirements impair overall cardiovascular drug adherence.

Methods: A cohort study was performed with hospitalized patients at high risk of cardiovascular disease between April and September 2011. Patients were asked whether the prescribed time for taking their statin and antiplatelet drugs created any inconvenience in their daily routine and, if so, were asked to describe the reasons.
