Dihydropyridine vs. Nondihydropyridine: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 28, 2024
Dihydropyridines are a class of calcium channel blockers mainly affecting vascular smooth muscles, while nondihydropyridines also block calcium channels but predominantly affect the heart.

Key Differences

Dihydropyridines, a group of medications, primarily act on vascular smooth muscles, causing vasodilation and reducing blood pressure. Nondihydropyridines, another group within the calcium channel blockers, have a more significant effect on the heart muscle, affecting heart rate and contraction strength.

The dihydropyridine class includes drugs like amlodipine and nifedipine, known for their effectiveness in treating hypertension. Nondihydropyridines such as verapamil and diltiazem are used not only for hypertension but also for their effects on cardiac arrhythmias and angina.

Dihydropyridines work by selectively blocking L-type calcium channels in the vascular smooth muscle, leading to vasodilation. Nondihydropyridines also block these channels but are more selective for cardiac muscle, thereby reducing heart rate and contractility.

In terms of side effects, dihydropyridines are commonly associated with peripheral edema and flushing due to their vasodilatory actions. Nondihydropyridines, on the other hand, can cause bradycardia and negative inotropic effects, reflecting their cardiac effects.

When considering drug interactions, dihydropyridines may have interactions that affect their metabolism and blood pressure-lowering effect. Nondihydropyridines have a different set of interactions, often involving drugs that affect cardiac function or rhythm.
