Nifedipin Retard Denk (Nifedipine)

Nifedipine, the active ingredient in Nifedipin Retard Denk, is a calcium channel blocker formulated as an extended‑release tablet for oral administration. It is used to lower elevated blood pressure and to relieve chest pain caused by chronic stable angina in adult patients.

GNH USA supplies Nifedipin Retard Denk as a licensed, Good Distribution Practice‑compliant product, providing reliable access to hospitals, pharmacies and clinics worldwide through its established international supply network. The company adheres to stringent quality standards and regulatory requirements across EU and other markets.

Nifedipine is a calcium channel blocker indicated for conditions related to vascular tone and myocardial oxygen demand.

- Hypertension: reduces systolic and diastolic blood pressure, improving overall cardiovascular risk. - Chronic stable angina: decreases the frequency of angina attacks by enhancing coronary blood flow. - Hypertension with coronary artery disease: helps control blood pressure while also addressing myocardial oxygen demand in patients with co‑existing coronary disease.

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 reddening of the skin. - Peripheral edema: swelling of ankles or lower legs. - Dizziness: sensation of light‑headedness, especially when standing quickly.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure that can cause fainting. - Myocardial infarction: rare occurrence of heart attack during therapy. - Severe allergic reaction: includes rash, itching, swelling, or difficulty breathing.

When prescribing Nifedipin Retard Denk, clinicians should consider several safety measures.

- Monitor blood pressure: check regularly after initiation and dose adjustments. - Assess cardiac status: use caution in patients with heart failure or recent myocardial infarction. - Avoid abrupt discontinuation: taper the dose to prevent rebound hypertension. - Use with caution in hepatic impairment: dose modification may be required. - Store at ambient temperature: keep in the original container, protect from moisture and light.

Nifedipine can interact with several drug classes, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): may increase nifedipine plasma levels. - Grapefruit juice: can raise systemic exposure and risk of hypotension. - Concurrent potent vasodilators: heightened risk of severe blood pressure fall.

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