Abstract
Experiments were conducted out on 7 conscious, renal hypertensive dogs with 7 .beta.-adrenoceptor blocking agents (atenolol, bunitrolol, bunolol, carteolol, nadolol, sotalol and timolol). Three main conclusions were made: the stronger the .beta.-adrenoceptor blocking activity the stronger the antihypertensive action; for the antihypertensive action, very strong .beta.-adrenoceptor blocking activity was needed; d-carteolol, unlike dl-carteolol, had no antihypertensive effect. The .beta.-adrenoceptor blocking action is a prerequisite for the antihypertensive effect of the .beta.-adrenoceptor blocking agents.
