Comparison of the antihypertensive effects of carvedilol and metoprolol on resting and exercise blood pressure.
The present study was conducted to assess the efficacy and safety of carvedilol 50 mg as compared to metoprolol 200 mg at rest and during and after a standardized bicycle ergometric exercise test. Carvedilol is a novel non-selective beta-blocker without intrinsic sympathomimetic activity possessing vasodilatory properties primarily due to an alpha 1-antagonism in the same dose range. Both drugs were effective in reducing systolic and diastolic blood pressure at rest and during and after exercise. The reduction of diastolic blood pressure was much stronger under carvedilol treatment than under metoprolol treatment at all measurement points. Carvedilol was even effective in the treatment of patients whose blood pressure was unsatisfactorily controlled by metoprolol. This shows the importance of the vasodilation component of carvedilol. No serious adverse events were observed. Carvedilol therefore promises very well as a powerful and safe drug for the treatment of essential arterial hypertension.
