What is the recommended daily dosage range for oral Nifedipine in managing hypertension?

The recommended daily dosage range for oral Nifedipine in managing hypertension is typically 30-120 mg. Nifedipine is a calcium channel blocker that exerts its antihypertensive effects through the relaxation of vascular smooth muscle, leading to decreased peripheral vascular resistance.

The effective dosing range allows for titration based on patient response and tolerance to the medication. Starting doses may be lower, but the range of 30-120 mg ensures that sufficient therapeutic effects can be achieved while minimizing adverse effects. Indeed, dosages above this range may not provide additional benefits and could increase the risk of side effects, such as peripheral edema or reflex tachycardia.

The other options do not align with current dosing guidelines. The lower range is insufficient for effective blood pressure management, while the higher ranges may exceed recommended usage and risk poorer outcomes. Therefore, the range of 30-120 mg is the most appropriate and clinically acknowledged for treatment efficacy.
