What is nicardipine?
Nicardipine is a prescription medication in the “calcium channel blocker” (CCB) class. It works by relaxing blood vessels, which lowers blood pressure. Nicardipine is used to treat hypertension (high blood pressure) and, in some clinical settings, to control blood pressure during acute care.
How does nicardipine work?
Nicardipine blocks calcium entry into smooth muscle cells in blood vessel walls. With less calcium inside these cells, the vessel walls relax (vasodilation), reducing vascular resistance and lowering blood pressure.
What is nicardipine used for?
The main use is treating high blood pressure. Depending on the formulation and setting, it may also be used for short-term blood pressure control in acute situations under medical supervision.
What forms does nicardipine come in?
Nicardipine is available in more than one formulation (commonly oral and injectable forms), with dosing depending on the indication and whether the patient needs immediate versus longer-term blood pressure control.
What are common side effects people ask about?
Common side effects reported with calcium channel blockers can include dizziness, headache, flushing, and swelling (edema). As with any blood pressure medicine, it can also lower blood pressure too much in some patients.
Is nicardipine the same as other “-dipine” drugs?
Nicardipine is related to other dihydropyridine calcium channel blockers (like nifedipine and amlodipine), but it is not the same drug. They can differ in onset, duration, and typical dosing schedules, even though they share a similar mechanism of action.
