Which of the following Beta blocker is contraindicated in renal failure?
High-Yield Explanation
Sotalol is a non specific beta adrenergic receptor blocker. It shoens the sinus cycle period, lengthens the atrial and ventricular refractory period and QT interval. It has negative ionotropic effect and can reduce left ventricular contractile force and increase filling pressure. It is excreted by the kidneys with an elimination half life of 10-15 hours, so it should be avoided in renal failure. Ref: SCAI Interventional Cardiology Board Review Book By Moon J.
