Which of the following is not an inotropic drug?

Cardiac glycosides
Phosphodiesterase inhibitors
Calcium channel blockers
Sympathomimetics

Explanation

Answer: C - Calcium channel blockers are not inotropic drugs. They inhibit the movement of calcium into the myocardial cells. This results in decreased force of cardiac contraction and decreased cardiac conduction. Inotropic drugs increase the force of cardiac contraction. Inotropic drugs include cardiac glycosides, phosphodiesterase inhibitors, and sympathomimetics.
