Used primarily in the treatment of hypertension (high blood pressure). It belongs to the class of calcium channel blockers, which work by relaxing the blood vessels, allowing the heart to pump blood more easily. This helps reduce the risk of stroke, heart attack, and kidney problems associated with long-term high blood pressure. Lercanidipine is known for its long duration of action, allowing for once-daily dosing, and has a slower onset which may result in fewer side effects like reflex tachycardia or flushing compared to other calcium channel blockers. It is often prescribed when other antihypertensive medications are not well tolerated.
