What is 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, helping to lower blood pressure and improve chest‑pain symptoms.
GNH USA supplies Norvasc as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Amlodipine used for?
Norvasc is a calcium channel blocker used in cardiovascular disease management. - Hypertension: lowers systemic blood pressure and reduces the risk of cardiovascular complications. - Chronic stable angina: improves exercise tolerance and decreases the frequency of angina episodes.
What are the side effects of Amlodipine?
Adverse reactions may vary in frequency and severity.
Common Side Effects: - Headache: mild to moderate intensity, often transient. - Peripheral edema: swelling of the ankles or lower legs. - Flushing: warm sensation and reddening of the skin. - Dizziness or light‑headedness, especially after standing.
Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure requiring medical attention. - Myocardial infarction: rare occurrence of heart attack. - Allergic reactions: rash, pruritus, or angioedema that may necessitate discontinuation.
What precautions apply to Amlodipine?
Before initiating therapy, consider the following safety measures. - Monitor blood pressure: ensure adequate control and avoid excessive lowering. - Assess cardiac function: use caution in patients with heart failure or recent myocardial infarction. - Use caution in hepatic impairment: dose adjustments may be required. - Avoid abrupt discontinuation: tapering can prevent rebound hypertension. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.
What does Amlodipine interact with?
Amlodipine may interact with several medicines; awareness helps prevent adverse outcomes.
Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., clarithromycin, itraconazole): may increase amlodipine plasma levels. - High‑dose simvastatin (>20 mg): risk of myopathy and rhabdomyolysis. - Grapefruit juice: can elevate drug concentrations.
Moderate Interactions (Monitor Closely):\n- Beta‑blockers: additive effects on heart rate and blood pressure. - Diuretics: may enhance antihypertensive response, requiring dose adjustment. - CYP3A4 inducers (e.g., rifampin, carbamazepine): may reduce amlodipine effectiveness.
