This medication is used to treat high blood pressure and prevent certain types of chest pain. It works by relaxing blood vessels so the heart does not have to pump as hard. It may be used during pregnancy under a doctor's supervision, and caution is advised while breastfeeding.

Indications

Nifedipine is indicated in the management of all types of essential & renal hypertension. Also indicated in the management of hypertension during pregnancy & during coronary by pass surgery.

Nifedipine is also used for prophylaxis and the treatment of unstable & variant angina, myocardial infarction, and silent myocardial ischaemia. Moreover Nifedipine is also used in Raynaud's phenomenon & heart failure.

Pharmacology

Nifedipine is an inhibitor of Calcium Channel Blocker that blocks the transmembrane influx of Calcium ions into muscle cells. Nifedipine has selective effects as a dilator of arterial vessels. Nifedipine dilates main coronary and systemic arteries. As a result blood pressure falls and this elicits a sympathetic reflex response causing tachycardia and an increased cardiac output. Pulmonary arterial pressure also falls. Nifedipine has direct negative inotropic effects on cardiac muscles and these effects are seen at higher doses than dose which causes arterial vasodilatation.

Dosage & Administration

Do not take any medication without a doctor's prescription. Self-medication can be dangerous.
