WebNifedipine is a predominant arteriolar vasodilator, with minimal effect on venous capacitance vessels and no direct depressant effect on heart rate conduction. It may be administered intravenously, orally or sublingually, and has a rapid onset of action (2–5 minutes) and duration of action of 20–30 minutes. WebIn contrast peripheral pressor mechanisms including those mediated by angiotensin II and noradrenaline are antagonised. The long term efficacy of nifedipine in hypertension probably depends on its direct vasodilator effect, the preservation of depressor mechanisms and attenuation of reflex responses and direct and indirect pressor mechanisms.
