IMPROVED BLOOD PRESSURE CONTROL BY MONITORING COMPLIANCE WITH ANTIHYPERTENSIVE THERAPY

Compliance with antihypertensive therapy was monitored for three months using an electronic medication dispenser in 35 patients remaining hypertensive despite the once-daily administration of a blood pressure lowering drug (either as monotherapy or as fixed-dose combination therapy). During the monitoring of compliance, the treatment was unchanged but blood pressure decreased significantly (p < 0.001) from 167.9/100.4 +/- 16.3/7.2 mmHg (mean +/- SD) to 152.5/90.9 +/- 20.9/11.5 mmHg. The percentage of days with one opening per day was 80.8 +/- 20.5. Thus, discussing with the patient about compliance with the prescribed drug regimen and monitoring compliance for a few months allows better control of blood pressure. This most likely reflects increased compliance with antihypertensive drug therapy.
