Which therapeutic classification does Nifedipine belong to?

Nifedipine is classified specifically as a dihydropyridine calcium channel blocker (CCB). This classification is based on its chemical structure and how it functions in the body. Dihydropyridines, which include drugs like nifedipine, primarily affect the vascular smooth muscle, leading to vasodilation and a subsequent decrease in blood pressure. This is particularly useful in the treatment of conditions such as hypertension and angina.

While it is true that nifedipine is indeed a calcium channel blocker, the term "dihydropyridine" is essential because it distinguishes it from other types of calcium channel blockers, such as phenylalkylamines (like verapamil) and benzothiazepines (like diltiazem), which have different profiles of action and side effects. Understanding this distinction helps to clarify how various medications within the same broad category can have differing clinical uses and impacts.
