What is Nicorandil?
Nicorandil, the active ingredient in Nicorandil Viatris, is a potassium channel opener / nitrate presented as an oral tablet for oral use. It treats stable angina pectoris in adult patients by reducing chest pain episodes and improving exercise tolerance.
GNH USA supplies Nicorandil Viatris as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Nicorandil used for?
Nicorandil is used in the management of coronary artery disease and related angina syndromes.
- Stable angina pectoris: reduces the frequency of chest pain attacks and improves exercise capacity. - Chronic stable angina: decreases myocardial oxygen demand and alleviates ischemic symptoms. - Ischemic heart disease: helps relieve myocardial ischemia associated with angina.
What are the side effects of Nicorandil?
Nicorandil may cause a range of adverse reactions, from mild to severe.
Common Side Effects: - Headache: mild to moderate, often transient. - Flushing: warmth and redness of the skin. - Dizziness or light‑headedness, especially on standing. - Nausea or abdominal discomfort. - Palpitations or tachycardia. - Mild hypotension: reduced blood pressure without syncope.
Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure causing fainting. - Myocardial infarction: rare worsening of heart attack risk. - Stevens‑Johnson syndrome or severe skin reactions. - Angina exacerbation or new‑onset chest pain. - Anaphylactic or severe allergic reactions. - Hepatic dysfunction: abnormal liver enzymes.
What precautions apply to Nicorandil?
Before initiating Nicorandil therapy, consider the following safety measures.
- Contraindication: severe hypotension or cardiogenic shock. - Avoid use with other nitrates or potent vasodilators. - Caution in recent myocardial infarction: monitor cardiac status. - Monitor blood pressure regularly, especially after dose changes. - Pregnancy and lactation: safety not established; use only if benefit outweighs risk. - Discontinue gradually: abrupt cessation may precipitate rebound angina. - Store below 25°C: keep in the original pack, protect from moisture.
What does Nicorandil interact with?
Nicorandil can interact with several drug classes, requiring careful management.
Major Interactions (Avoid): - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): risk of profound hypotension. - Other nitrates or nitrovasodilators: additive vasodilatory effect. - Potent vasodilators (e.g., hydralazine): may cause severe blood pressure drops.
Moderate Interactions (Monitor Closely): - Antihypertensives (ACE inhibitors, ARBs, beta‑blockers): monitor for additive blood pressure lowering. - Diuretics: may enhance hypotensive response. - Calcium channel blockers: observe for synergistic vasodilation. - Alcohol: can increase dizziness and hypotension. - Antiplatelet agents: watch for bleeding tendency.
