What is Nitrendipine?
Nitrendipine, the active ingredient in Nitrendipin Al, is a calcium channel blocker presented as a tablet for oral use. It lowers elevated blood pressure in adults with hypertension.
GNH USA supplies Nitrendipin Al as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Nitrendipine used for?
Nitrendipine is a dihydropyridine calcium channel blocker used to manage hypertension and related vascular conditions.
- Hypertension: reduces systolic and diastolic blood pressure in adults. - Chronic stable angina: improves myocardial oxygen supply by decreasing after‑load. - Peripheral vascular disease: enhances blood flow by vasodilation of peripheral arteries.
What are the side effects of Nitrendipine?
Nitrendipin Al may cause a range of adverse reactions, most of which are mild and reversible.
Common Side Effects: - Headache: mild to moderate intensity. - Flushing: transient warmth and redness of the skin. - Peripheral edema: swelling of ankles or lower legs. - Dizziness: especially upon standing. - Nausea: occasional gastrointestinal upset. - Tachycardia: increased heart rate.
Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure leading to fainting. - Myocardial infarction: rare occurrence of heart attack. - Hepatic dysfunction: elevated liver enzymes or jaundice. - Allergic reactions: rash, pruritus, or anaphylaxis. - Arrhythmias: abnormal heart rhythms.
What precautions apply to Nitrendipine?
Before initiating therapy, clinicians should consider several safety factors.
- Blood pressure monitoring: assess baseline and follow‑up readings. - Hepatic impairment: use with caution; dose adjustment may be required. - Abrupt discontinuation: avoid sudden stop to prevent rebound hypertension. - Elderly patients: start at lower dose and monitor for orthostatic effects. - Severe hypotension: contraindicated in patients with markedly low blood pressure. - Store at below 25°C: keep in the original pack, protect from moisture and direct sunlight.
What does Nitrendipine interact with?
Nitrendipin Al can interact with other medicines, influencing its efficacy or safety.
Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin): increase plasma levels and risk of hypotension. - Grapefruit juice: may elevate drug concentrations. - Other antihypertensives (e.g., ACE inhibitors, beta‑blockers): additive blood‑pressure lowering effect.
Moderate Interactions (Monitor Closely): - CYP3A4 inducers (e.g., rifampin, carbamazepine): reduce effectiveness. - Non‑dihydropyridine calcium channel blockers: potential for bradycardia. - NSAIDs: may blunt antihypertensive response. - Diuretics: monitor electrolytes and renal function.
