What is Nicardipine used for?
Nicardipine is a calcium channel blocker primarily used to treat high blood pressure (hypertension) [1]. It is also used to manage angina (chest pain) [1].
How does Nicardipine work?
As a dihydropyridine calcium channel blocker, nicardipine works by relaxing and widening blood vessels [1]. This action reduces the resistance blood encounters as it flows through the body, thereby lowering blood pressure and decreasing the workload on the heart, which can alleviate angina [1].

These medications also cause vasodilation to manage hypertension and angina, though they may differ in their pharmacokinetic profiles and clinical applications [3].
