    Abstract:
    Antihypertensive treatment regimen persistence and compliance were measured using a retrospective cohort study of pharmacy claims data. Newly treated patients receiving monotherapy with angiotensin II receptor blockers (ARBs), angiotensin-converting enzyme inhibitors (ACEIs), calcium channel blockers (CCBs), beta-blockers (BBs), or diuretics were followed for 1 year (N=242,882). A higher proportion of ARB patients (51.9%) were persistent in taking prescribed medication compared with those in the ACEI (48.0%), BB (40.3%), CCB (38.3%), and diuretic groups (29.9%). Compared with patients receiving diuretics, those receiving ARBs (hazard ratio [HR], 0.593; P<.0001), ACEIs (HR, 0.640; P<.0001), CCBs (HR, 0.859; P<.0001), and BBs (HR, 0.819; P<.0001) were all less likely to discontinue therapy. Compliance was similar in ACEI and ARB patients, but patients receiving ARBs and ACEIs had better compliance than those receiving BBs, CCBs, or diuretics. The lesser degree of compliance and persistence observed in patients receiving diuretics compared with other antihypertensive medications may have public health as well as cost implications.
