Abstract: | SUMMARY The antianginal efficacy of a fixed combination of atenolol (50 mg) and nifedipine (20 mg) was compared with nifedipine (20 mg) alone; 102 patients experiencing three or more anginal attacks on their current monotherapy received each treatment twice daily for 3 weeks in a randomised, double-blind crossover trial. Both treatments reduced the weekly number of angina attacks compared with existing therapy; treatment with the fixed combination resulted in significantly fewer angina attacks per week than treatment with nifedipine alone. Also, when the fixed combination treatment followed the period of nifedipine therapy a further decrease in weekly angina attack rate was apparent. Comparison of individual patient response to each treatment showed that twice as many patients reported lower attack rates while on the fixed combination: 6 patients were withdrawn while receiving fixed combination compared with 10 patients on nifedipine alone. However, the incidence of commonly reported complaints was similar with both treatments. |
