Amlodipine, marketed as Norvalet, is used to manage cardiovascular conditions that involve elevated vascular tone.

Hypertension: lowers systemic blood pressure by relaxing arterial smooth muscle. Chronic stable angina: reduces frequency of chest pain episodes by improving coronary blood flow. Vasospastic angina: prevents coronary artery spasm, decreasing angina attacks.

Amlodipine may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects: - Headache: mild to moderate intensity. - Flushing: transient warmth and redness. - Peripheral edema: swelling of ankles or feet. - Dizziness: especially upon standing. - Fatigue: general tiredness. - Palpitations: sensation of rapid heartbeat.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure. - Myocardial infarction: rare occurrence of heart attack. - Hepatic dysfunction: abnormal liver enzymes. - Allergic reactions: rash, itching, or hives. - Angioedema: swelling of face, lips, or throat. - Tachycardia: rapid heart rate.

When prescribing amlodipine, several precautions should be observed to ensure safe use.

Monitor blood pressure: adjust dose based on therapeutic response. Assess hepatic function: use caution in patients with liver impairment. Avoid abrupt discontinuation: taper to prevent rebound hypertension. Evaluate for heart failure: monitor for signs of fluid retention. Review concomitant antihypertensives: risk of additive hypotension. Store at room temperature: keep in original packaging, protect from moisture.

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

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., clarithromycin, itraconazole): may increase amlodipine levels. - Concurrent use with other potent antihypertensives: risk of excessive blood pressure drop. - Grapefruit juice: can elevate plasma concentrations.

Moderate Interactions (Monitor Closely): - CYP3A4 inducers (e.g., rifampin, carbamazepine): may reduce effectiveness. - Diuretics: may enhance electrolyte disturbances. - NSAIDs: can diminish antihypertensive effect. - Beta‑blockers: may mask tachycardia signs. - Digoxin: possible increase in serum digoxin levels.
