Nifedipina Generis (Nifedipine)

Nifedipine, the active ingredient in Nifedipina Generis, is a calcium channel blocker presented as an oral tablet for oral use. It is employed to manage high blood pressure, chest pain from angina, and peripheral vascular disorders such as Raynaud's phenomenon.

GNH USA supplies Nifedipina Generis as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company follows EU manufacturing standards and provides full regulatory documentation for global distribution.

Nifedipine acts on the cardiovascular system to lower vascular resistance, making it useful for several related conditions.

Hypertension: reduces systolic and diastolic blood pressure by causing arterial vasodilation. Angina pectoris: relieves chest pain by improving coronary blood flow. Raynaud's phenomenon: diminishes frequency and severity of vasospastic attacks in the extremities.

Nifedipine may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects: - Headache - Flushing - Peripheral edema - Dizziness

Serious or Rare Side Effects: - Severe hypotension - Cardiac arrhythmia - Hepatotoxicity (rare)

Before initiating therapy, clinicians should consider several safety measures.

Monitor blood pressure: check regularly after dose initiation. Assess cardiac function: avoid in patients with severe aortic stenosis. Review concomitant medications: consider interactions with CYP3A4 inhibitors. Use caution in hepatic impairment: dose may need adjustment. Store at ambient temperature below 25°C: keep in the original container, protect from moisture and light.

Nifedipine can interact with several drug classes, requiring careful management.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole) may increase plasma concentrations. - Grapefruit juice can markedly raise nifedipine levels. - Concurrent use with other potent vasodilators (e.g., nitroglycerin) may cause severe hypotension.

Moderate Interactions (Monitor Closely): - Beta‑blockers: may mask tachycardia. - Diuretics: additive blood‑pressure‑lowering effect. - Digoxin: potential increase in serum digoxin concentrations.
