Used primarily in the treatment of hypertension (high blood pressure). It works by relaxing blood vessels, allowing blood to flow more smoothly and the heart to pump more efficiently. As a calcium channel blocker, it selectively targets vascular smooth muscle, reducing peripheral resistance without significant effects on heart rate. Its long duration of action allows for once-daily dosing, improving patient compliance. Due to its lipophilic nature, it has a slow onset and prolonged effect, minimizing reflex tachycardia. Commonly prescribed for patients requiring sustained blood pressure control, especially those sensitive to side effects from other antihypertensives.
