Norvasc (Amlodipine)

Amlodipine, the active ingredient in Norvasc, is a calcium channel blocker presented as a tablet for oral use. It lowers elevated blood pressure and relieves chest pain caused by chronic stable angina in adult patients and is commonly prescribed as part of cardiovascular risk management.

GNH USA supplies Norvasc as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides reliable logistics for global distribution. Customers benefit from consistent batch release, traceability, and regulatory support across regions.

Norvasc (amlodipine) is used to manage cardiovascular conditions by relaxing vascular smooth muscle.

Hypertension: lowers both systolic and diastolic blood pressure, facilitating achievement of guideline‑recommended targets and reducing cardiovascular strain. Chronic stable angina: dilates coronary arteries and reduces cardiac afterload, thereby decreasing the frequency and severity of angina attacks. Coronary artery disease: diminishes myocardial oxygen demand and improves perfusion, contributing to lower risk of ischemic complications in patients with established CAD.

Amlodipine may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects: - Headache: mild to moderate headache is frequently reported. - Peripheral edema: swelling of the ankles or lower legs may occur. - Flushing: transient warmth and redness of the skin can be experienced. - Dizziness: light‑headedness, especially after standing, is possible.

Serious or Rare Side Effects: - Severe hypotension: markedly low blood pressure requiring medical attention. - Myocardial infarction: rare cases of heart attack have been reported. - Hepatic enzyme elevation: significant increase in liver transaminases may occur. - Allergic reactions: including rash, angioedema, or anaphylaxis in rare instances.

When prescribing amlodipine, clinicians should consider several precautionary measures to ensure safe use. - Blood pressure monitoring: regularly assess to avoid excessive hypotension. - Hepatic impairment: use caution and consider dose adjustment in patients with liver disease. - Heart failure: monitor for worsening symptoms, especially in decompensated cases. - Concomitant beta‑blockers: observe for additive bradycardia or AV block. - Pregnancy: category B; use only if benefit outweighs potential risk. - Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

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

Major Interactions (Avoid): - Simvastatin >20 mg: increased risk of statin‑related myopathy. - Cyclosporine: elevated amlodipine levels may cause hypotension. - Grapefruit juice: can raise amlodipine concentrations, enhancing adverse effects.

Moderate Interactions (Monitor Closely): - Beta‑blockers: additive effects on heart rate and blood pressure. - Diuretics: may potentiate orthostatic hypotension.
