Select and explain. 
A. It is non selective Beta blocker, B. It prolongs the action potential duration throughout the hea, C. It is excreted through bile following hepatic metabolism, D. Polymorphic ventricular tachycardia is a common problem
C: It is excreted through bile following hepatic metabolism
Answer: C: It is excreted through bile following hepatic metabolism 
Explanation: Refer kDT 6/e 140,515 sotolol is a non selective Beta blocker (potassium channel blocker) class 3 antiarrhythmic propey. It prolongs APD by blocking the cardiac potassium channels.
