we studied the interaction of amiodarone hydrochloride ( cordarone ) and its major metabolite desethylamiodarone with the muscarinic receptor in purified canine cardiac sarcolemmal vesicles by measuring equilibrium binding of the muscarinic antagonist [ 3h ] quinuclidinyl benzilate ( qnb ) and carbachol displacement of [ 3h ] -qnb .
