Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialAntianginal efficacy of the combination of felodipine-metoprolol 10/100 mg compared with each drug alone in patients with stable effort-induced angina pectoris: a multicenter parallel group study. The TRAFFIC Study Group.
The primary objective of this randomized, double-blind, parallel group trial was to compare the antianginal and antiischemic efficacy of a combination tablet of felodipine-metoprolol 10/100 mg once daily with both drugs given separately once daily in patients with stable effort-induced angina pectoris. The secondary objective was to compare the tolerability of the 3 treatments. ⋯ In stable angina pectoris, the combination felodipine-metoprolol 10/100 mg and felodipine 10 mg alone increased exercise time compared with metoprolol 100 mg. The combination tablet and metoprolol 100 mg alone showed a more favorable tolerability profile than felodipine 10 mg alone.
