[{'content': 'Beta adrenergic blocker having cardioselectivity, intrinsic sympathomimetic activity and membrane stabilizing propey is: \nSelect and explain. \nA. Carvedilol, B. Atenolol, C. Acebutolol, D. Metoprolol', 'role': 'user'}, {'content': 'Answer: C \nExplanation: Acebutolol is cardioselective Beta blocker with intrinsic sympathomimetic activity and membrane stabilizing propey * Cardioselective Beta blockers : Metoprolol, Atenolol , Acebutolol , Bisoprolol , Nebivolol These drugs are more potent in blocking cardiac (Beta 1) than bronchial (Beta 2) receptors. However, selectivity is only relative and is lost at high doses. * Beta blockers with membrane stabilizing activity : Propranolol , Oxprenolol , Acebutolol contribute to the antiarrhythmic action', 'role': 'assistant'}]
