The following statement is not true about sotolol: (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
Answer is C. 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. Therefore prolongs QT interval and results in torsedes points ( polymorphic ventricular tachycardia) It is lipid insoluble Beta blocker that is excreted predominantly by kidney.
