Application Number:	05/277,607
Patent Claims:	1. A pharmaceutical composition which comprises, as the active ingredient, an effective amount for the treatment or prophylaxis of angina pectoris or cardiac arrhythmia of a compound of the formula: ##SPC7## wherein R.sup.1 represents alkanoylamino of one through nine carbon atoms, R.sup.2 represents alkyl of one through six carbon atoms, and R.sup.3 represents alkyl of one through six carbon atoms or cycloalkyl of three through six carbon atoms, or a non-toxic acid addition salt thereof, in association with a pharmaceutically-acceptable carrier. 2. A method of treatment or prophylaxis of a cardiac disorder in a patient suffering from angina pectoris or cardiac arrhythmia which comprises administering orally or intravenously to the patient a compound of the formula: ##SPC8## wherein R.sup.1 represents alkanoylamino of one through nine carbon atoms, R.sup.2 represents alkyl of one through six carbon atoms, and R.sup.3 represents alkyl of one through six carbon atoms or cycloalkyl of three through six carbon atoms, or a non-toxic acid addition salt thereof, when administered orally in an amount between 1 and 10 mg/kg body weight per day and when administered intraveneously in an amount between 0.1 and 0.5 mg/kg body weight per day. 3. The method according to claim 2 in which the said compound is 5'-butyramido-2'-(2-hydroxy-3-isopropylaminopropoxy) acetophenone or a non-toxic acid addition salt thereof.
