Comparison of intravenous AH 5158 (ibidomide) and propranolol in asthma. 1975

C Skinner, and J Gaddie, and K N Palmer

The cardiac and bronchial effects of AH 5158 and propranolol were compared in a double-blind, placebocontrolled intravenous study on 10 asthmatics. AH 5158, like propranolol, is a non-cardioselective beta-adrenoceptor-blocking drug, but unlike propranolol it also has an alpha-adrenoceptor-blocking action. Both drugs produced equivalent cardiac(beta1) blockade, but propranolol produced bronchoconstriction, whereas AH 5158 did not. Hence the alpha-blocking action of AH 5158 seems to prevent the bronchoconstrictor effects of propranolol in these patients.

D010919	Placebos	Any dummy medication or treatment. Although placebos originally were medicinal preparations having no specific pharmacological activity against a targeted condition, the concept has been extended to include treatments or procedures, especially those administered to control groups in clinical trials in order to provide baseline measurements for the experimental protocol.	Sham Treatment
D011433	Propranolol	A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.
