Nifedipine Sandoz

Nifedipine, the active ingredient in Nifedipine Sandoz, is a calcium channel blocker presented as an oral dosage form for oral use. It treats hypertension, angina pectoris, and Raynaud's phenomenon in adult patients.

GNH USA supplies Nifedipine Sandoz as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Nifedipine is used to manage cardiovascular conditions that involve excessive vascular tone or myocardial oxygen demand. - Hypertension: lowers elevated blood pressure by relaxing arterial smooth muscle. - Angina pectoris: reduces chest pain by decreasing cardiac workload and improving coronary blood flow. - Raynaud's phenomenon: alleviates vasospastic attacks in peripheral arteries, improving blood flow to the fingers and toes.

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

Common Side Effects: - Headache: mild to moderate pain often occurring shortly after dosing. - Flushing: transient warmth and redness of the skin. - Peripheral edema: swelling of the ankles or lower legs. - Dizziness: sensation of light‑headedness, especially when standing. - Tachycardia: increased heart rate as a reflex response. - Nausea: mild gastrointestinal upset.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure that may cause fainting. - Myocardial infarction: rare occurrence of heart attack, particularly in patients with pre‑existing coronary disease. - Allergic reactions: rash, itching, or anaphylaxis. - Liver dysfunction: elevated liver enzymes indicating hepatic injury. - Atrioventricular block: abnormal heart rhythm requiring medical attention. - Seizures: rare neurologic events.

Before prescribing Nifedipine, clinicians should consider several safety measures. - Blood pressure monitoring: regularly assess to avoid excessive hypotension. - Hepatic impairment: adjust use in patients with liver disease due to altered metabolism. - Abrupt discontinuation: taper gradually to prevent rebound hypertension. - Heart failure: use cautiously as rapid vasodilation may worsen symptoms. - Concomitant antihypertensives: evaluate for additive blood‑pressure‑lowering effects. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Nifedipine can interact with other medicines, influencing its efficacy or safety.

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

Moderate Interactions (Monitor Closely):\n- CYP3A4 inducers (e.g., rifampicin, carbamazepine): may reduce therapeutic effect. - Beta‑blockers: additive heart‑rate‑lowering effect. - Diuretics: enhanced blood‑pressure reduction. - NSAIDs: may blunt antihypertensive response. - Antidiabetic agents: monitor glucose as blood‑pressure changes can affect glycemic control.
