We have studied the efficacy and tolerability of felodipine plus a beta-adrenoceptor blocker in 79 patients with essential hypertension previously treated with a combination of three or more anti-hypertensive agents, one of which was a beta-adrenoceptor blocker. After a 4-week run-in period on the same beta-blocker plus placebo (as a substitute for the other agents in the regimen), felodipine was added and its dose titrated to achieve a supine diastolic blood pressure or less than 90 mm Hg. This was followed by a 12-week maintenance phase in all patients, and 47 patients entered an optional long-term follow-up for an additional 9 months. The mean supine blood pressure was 149/88 mm Hg at entry and 174/108 mm Hg after the run-in phase. Felodipine significantly reduced the blood pressure to 142/85 mm Hg after dose titration and to 141/84 mm Hg after 12 weeks, 94% of patients achieving a supine diastolic blood pressure of 90 mm Hg or below. This reduction was maintained in the patients who were followed for 12 months. The adverse events recorded were usually mild, transient, and typical for an effective precapillary vasodilator. Nine of 74 patients (11%) were withdrawn in the first phase of the study because of adverse events and 5 of 47 patients were withdrawn during the long-term follow-up. These results show that the efficacy and tolerability of a combination of felodipine with a beta-blocker allow a simplified regimen for hypertensive patients who were previously taking three or more drugs for satisfactory blood pressure control. |
