Comparative trial of atenolol and propranolol in hyperthyroidism. 1978

D G McDevitt, and J K Nelson

1 The use of atenolol, a cardioselective beta-adrenoceptor antagonist, in the management of hyperthyroidism has been studied by comparing it with propranolol. 2 In a double-blind cross-over trial, atenolol (50 mg), propranolol (40 mg) and placebo 4 times daily for 1 week were compared in twenty-one hyperthyroid patients by sequential analysis. 3. Patients generally preferred atenolol or propranolol to placebo but this preference only achieved significance with propranolol. 4 Judged by their effect on the symptoms and signs of hyperthyroidism, both atenolol and propranolol were significantly better than placebo, but no distinction could be made between the two active compounds. 5 Atenolol and propranolol reduced mean heart rate by 29.8 and 27.1% respectively compared with placebo. 6 Atenolol appeared almost equally effective to propranolol in the management of the peripheral manifestations of hyperthyroidism.

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
D011412	Propanolamines	AMINO ALCOHOLS containing the propanolamine (NH2CH2CHOHCH2) group and its derivatives.	Aminopropanols
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.
