Norvasc (Amlodipine)

Amlodipine, the active ingredient in Norvasc, is a calcium channel blocker presented as a tablet for oral use. It treats hypertension and chronic stable angina in adult patients by relaxing vascular smooth muscle and improving coronary blood flow. The product conforms to EU quality standards and is manufactured under strict Good Manufacturing Practice.

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

Norvasc belongs to the calcium channel blocker class and is indicated for cardiovascular conditions.

Essential hypertension: lowers systemic blood pressure and reduces cardiovascular risk. Secondary hypertension: assists in controlling elevated blood pressure when caused by underlying disorders. Chronic stable angina: decreases the frequency and severity of chest pain by improving myocardial oxygen supply.

Amlodipine may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects: - Headache: mild to moderate intensity. - Peripheral edema: swelling of the ankles or feet. - Flushing: sensation of warmth and redness. - Dizziness or light‑headedness. - Fatigue: general tiredness. - Palpitations: awareness of heartbeat.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure. - Myocardial infarction: rare occurrence of heart attack. - Elevated liver enzymes: signs of hepatic stress. - Allergic reactions: rash, itching, or swelling. - Stevens‑Johnson syndrome: severe skin reaction. - Hemorrhagic stroke: rare intracranial bleeding.

Before initiating therapy, certain safety considerations should be reviewed.

Monitor blood pressure: ensure adequate control without excessive lowering. Assess cardiac function: be cautious in patients with heart failure. Use caution in hepatic impairment: dose adjustments may be required. Avoid abrupt discontinuation: taper to prevent rebound hypertension. Pregnancy and lactation: consult a physician before use. Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

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

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., clarithromycin, itraconazole): increase amlodipine plasma levels. - High‑dose simvastatin (>20 mg): heightened risk of myopathy. - Lithium: elevated lithium concentrations may occur.

Moderate Interactions (Monitor Closely): - Beta‑blockers: additive hypotensive effect. - Diuretics: enhanced blood‑pressure reduction. - CYP3A4 inducers (e.g., rifampin, carbamazepine): may reduce amlodipine effectiveness.
