Nifedipina Alter (Nifedipine)

Nifedipine, the active ingredient in Nifedipina Alter, is a calcium channel blocker presented as a tablet for oral use. It is used to manage high blood pressure, relieve chest pain from angina, and improve blood flow in Raynaud's phenomenon, primarily in adult patients. GNH USA supplies Nifedipina Alter as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Nifedipine acts on the cardiovascular system by relaxing vascular smooth muscle, which is useful in several related conditions. Hypertension: lowers blood pressure by reducing peripheral vascular resistance. Chronic stable angina: decreases myocardial oxygen demand and alleviates chest pain. Raynaud's phenomenon: improves peripheral blood flow, reducing episodes of vasospasm.

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

Common Side Effects: - Headache: often mild and transient. - Flushing: warmth and redness of the skin. - Peripheral edema: swelling of the ankles or feet. - Dizziness or light‑headedness, especially on standing. - Nausea or abdominal discomfort. - Gingival hyperplasia: overgrowth of gum tissue.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure. - Myocardial infarction: rare but reported in high‑risk patients. - Atrioventricular block: conduction abnormalities. - Hepatotoxicity: liver enzyme elevations. - Severe allergic reactions: rash, swelling, or anaphylaxis. - Thrombocytopenia: low platelet count.

Before prescribing Nifedipina Alter, clinicians should consider several safety factors. - Cardiovascular disease: assess for severe aortic stenosis or recent myocardial infarction. - Liver impairment: dose adjustment may be required in hepatic dysfunction. - Concomitant antihypertensives: monitor for additive blood‑pressure lowering effects. - Elderly patients: start with lower doses and monitor for orthostatic hypotension. - Pregnancy and lactation: use only if the potential benefit justifies the potential risk. - Store at ambient temperature: keep below 25 °C, retain in original packaging, and protect from moisture.

Nifedipine can interact with several medicines, altering its efficacy or safety.

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

Moderate Interactions (Monitor Closely):\n- Beta‑blockers: may mask tachycardia but enhance antihypertensive effect. - Diuretics: increased risk of electrolyte imbalance and hypotension. - Antacids containing aluminum or magnesium: may reduce oral absorption; separate dosing by at least 2 hours.
