Hypertension (High Blood Pressure): To lower blood pressure and prevent long-term complications like stroke and heart failure. Renal Protection: Often prescribed for hypertensive patients with diabetes or kidney disease to reduce protein leakage in urine (proteinuria). Edema-Prone Patients: Used for patients who develop swelling in their feet or ankles while taking other blood pressure drugs.

Cilnidipine stands out due to its dual mechanism: L-type Channel Blockade: It relaxes the smooth muscles of the blood vessels (vasodilation), which reduces peripheral resistance and lowers blood pressure. N-type Channel Blockade: It inhibits the release of Norepinephrine from sympathetic nerve endings. This helps prevent "reflex tachycardia" (the racing heart feeling) and helps keep the pressure inside the kidneys low, protecting them over time.

Common: Headache, dizziness, flushing (warmth in the face), and palpitations. Digestive: Nausea or abdominal pain. Neurological: Fatigue or drowsiness. Rare: Mild swelling of the gums (gingival hyperplasia) or skin rash. Note: The incidence of pedal edema (ankle swelling) is significantly lower than with Amlodipine.
