<prompt> The following statement is not true about sotololIt is non selective Beta blockerIt prolongs the action potential duration throughout the heaIt is excreted through bile following hepatic metabolismPolymorphic ventricular tachycardia is a common problem  <response>: Refer kDT 6e 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.
