    Abstract:
    A multicenter, double-blind study was performed to compare the antianginal efficacy and safety of the new dihydropyridine calcium antagonist amlodipine with the benzothiazepine calcium antagonist diltiazem in patients with stable exertional angina pectoris. Following a 2-week placebo run-in period, 39 patients were randomized to receive amlodipine (2.5-10 mg once daily) and 41 patients to receive diltiazem (60-120 mg three times daily) in an 8-week double-blind treatment phase. The study used standardized bicycle exercise testing as a primary efficacy assessment. Patients also recorded angina frequency and nitroglycerin (NTG) tablet consumption/ week. Treatment with amlodipine and diltiazem resulted in an improvement in total exercise time, time to angina and total work, mean ST-segment deviation at maximum common load, median number of angina attacks/week, and NTG tablet consumption/week. The incidence and severity of possibly treatment-related side effects and laboratory test abnormalities were comparable for both drugs. The most frequently reported side effects were dizziness, headache, peripheral edema, and nausea. Two patients withdrew from diltiazem treatment due to pruritus in one case and severe headache and moderate dyspnea in the other. No amlodipine-treated patients withdrew due to side effects. In conclusion, this study demonstrated that the antianginal efficacy and tolerability of amlodipine is equivalent to diltiazem, but amlodipine has the advantage of once-daily dosing.
