What should be taken on an empty stomach?

Flecainide
Quinidine
Disopyramide
Lidocaine

The correct answer is: Disopyramide

Disopyramide should be taken on an empty stomach because food can decrease its absorption by up to 30%. This medication is a Class IA antiarrhythmic agent used to treat irregular heartbeats. Taking it on an empty stomach ensures optimal absorption and effectiveness of the drug. Options A, B, and D (Flecainide, Quinidine, and Lidocaine) do not necessarily need to be taken on an empty stomach and can be taken with food to reduce potential gastrointestinal side effects.
