Cardiac and bronchial beta-adrenoceptor antagonistic potencies of atenolol, metoprolol, acebutolol, practolol, propranolol and pindolol in the anaesthetized dog.
1. The beta-adrenoceptor antagonists atenolol, metoprolol, acebutolol, practolol, propranolol and pindolol have been tested for their ability to reduce isoprenaline-induced bronchodilation and tachycardia in the anaesthetized dog. 2. Atenolol, metoprolol, acebutolol and practolol all possessed a similar degree of cardioselectivity in this animal model.
