Pharmacology of Drugs Acting on Cardiovascular System Questions
Question 1 of 5
Which of the following drugs was most likely administered to the patient to prevent further fibrillatory episodes?
Correct Answer: D
Rationale: The correct answer is D: Amiodarone. Amiodarone is a potent antiarrhythmic drug commonly used to prevent fibrillatory episodes like atrial fibrillation. It has a broad spectrum of action, affecting multiple ion channels to stabilize cardiac rhythm. Mexiletine (A) is used for ventricular arrhythmias, not fibrillatory episodes. Sotalol (B) is also used for ventricular arrhythmias and can actually increase the risk of torsades de pointes in patients with atrial fibrillation. Quinidine (C) is an older antiarrhythmic that is less commonly used due to its potential for proarrhythmic effects.
