Norvasc (Amlodipine Besilate)

Amlodipine Besilate, the active ingredient in Norvasc, is a calcium channel blocker presented as an oral tablet for systemic use. It is indicated for the management of hypertension and for relief of chronic stable angina in adult patients, helping to lower blood pressure and improve myocardial oxygen supply.

GNH USA supplies Norvasc as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, providing reliable access to this essential antihypertensive and anti‑anginal medication.

Norvasc (amlodipine besilate) is a calcium channel blocker used in cardiovascular disease management.

Hypertension: lowers systolic and diastolic blood pressure to reduce cardiovascular risk. Chronic stable angina: improves coronary blood flow and reduces frequency of chest pain. Coronary artery disease: assists in symptom control and blood pressure management in patients with established disease.

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

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

Serious or Rare Side Effects: - Severe hypotension: markedly low blood pressure requiring medical attention. - Myocardial infarction: rare occurrence of heart attack. - Elevated liver enzymes: indicating possible hepatic stress. - Allergic reactions: rash, itching, or anaphylaxis. - Heart block: abnormal cardiac conduction requiring monitoring.

Before initiating therapy, clinicians should evaluate patient‑specific factors and monitor for potential risks.

Monitor blood pressure: ensure adequate control without excessive lowering. Assess for heart failure: watch for signs of fluid retention. Use caution in hepatic impairment: dose adjustments may be needed. Avoid abrupt discontinuation: taper to prevent rebound hypertension. Review concomitant CYP3A4‑modifying drugs: adjust therapy as required. Store at room temperature: keep in the original pack, protect from moisture and direct sunlight.

Amlodipine can interact with several medicines that affect its metabolism or additive blood‑pressure effects.

Major Interactions (Avoid): - Simvastatin >20 mg: increased risk of statin‑related myopathy. - Strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin): may raise amlodipine plasma levels. - Grapefruit juice: can elevate drug concentration and precipitate hypotension.

Moderate Interactions (Monitor Closely):\n- Beta‑blockers: additive effect on heart rate and blood pressure. - NSAIDs: may blunt antihypertensive response and affect renal function.
