The effects of felodipine in angina pectoris.
The clinical response to felodipine, in addition to a beta-blocker, was evaluated and compared with placebo in this double-blind cross-over study. Twenty patients with exertional angina pectoris completed the study. Felodipine reduced the number of angina attacks and the Glyceryl Trinitrate (GTN) consumption. The median exercise capacity was increased 33% after 4 weeks' felodipine treatment compared with placebo. At maximal exercise, systolic blood pressure and rate pressure product were reduced by felodipine while no change was seen in heart rate or ST-depression. Felodipine reduced both supine and erect blood pressure. The mean supine blood pressure at rest was 138/82 mm Hg after four weeks' placebo treatment compared with 114/71 mmHg after felodipine 5-10 mg b.i.d. Felodipine has overall a modest but significant anti-anginal benefit when combined with a beta-blocker.
