d) beta bloker

Answer 1

1. Verapamil drug is used for the treatment of hypertension. It relaxes muscles of the heart by blocking calcium channels. Its side effects include yellowing of the skin and eyes, dizziness, anxiety, and loss of appetite.

Sotalol is a beta blocker used to treat dysrhythmia. It can cause bronchospasm in asthmatic patients.

Amiodarone is used for treatment in patients of irregular heart beat. It blocks potassium currents responsible for repolarization of the heart. Its adverse effects include nausea, nerve damage, weakness, skin discolouration (blue-gray), and effect of lung.

Disopyramide is also an anti-arrhythmic drug which is a sodium channel blocker. It does not affect asthmatic patients and is used in asthmatic patients.

Answer is (b) sotalol.
