Nitrong (Glyceryl Trinitrate)

Glyceryl trinitrate, the active ingredient in Nitrong, is an organic nitrate presented as a transdermal patch for transdermal use. It provides vasodilation to relieve chest pain and is indicated for chronic stable angina, helping to prevent angina attacks in adult patients.

GNH USA supplies Nitrong as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, ensuring quality and regulatory compliance across markets. The product conforms to European Union pharmacopeial standards and is distributed under a prescription‑only framework.

Nitrong (glyceryl trinitrate) is used in the management of coronary artery disease‑related angina by providing nitric‑oxide mediated vasodilation. - Chronic stable angina: decreases frequency and severity of chest pain episodes. - Prevention of angina attacks: maintains coronary vasodilation to reduce occurrence of attacks. - Exercise‑induced angina: improves tolerance to physical exertion by enhancing myocardial blood flow.

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

Common Side Effects: - Headache: throbbing headache due to cerebral vasodilation. - Flushing: warmth and redness of the skin. - Dizziness: light‑headed sensation, especially on standing. - Hypotension: mild drop in blood pressure causing faintness. - Nausea: feeling of stomach upset. - Skin irritation at patch site: redness or itching where the patch is applied.

Serious or Rare Side Effects: - Severe hypotension: marked blood pressure fall leading to syncope. - Methemoglobinemia: elevated methemoglobin causing cyanosis. - Allergic reaction: rash, itching, swelling, or anaphylaxis.

When prescribing Nitrong, clinicians should consider several precautionary measures to ensure safe use. - Avoid use with phosphodiesterase‑5 inhibitors: risk of severe hypotension. - Monitor blood pressure: watch for excessive drops after patch application. - Assess for anemia or low hemoglobin: may exacerbate dizziness. - Advise patients to change patch site daily: reduce skin irritation. - Contraindicated in patients with known hypersensitivity to nitrates. - Store at room temperature: keep in original packaging, protect from moisture and light.

Glyceryl trinitrate can interact with other medicines, altering its efficacy or safety.

Major Interactions (Avoid): - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): may cause profound hypotension. - Other nitrates or nitroglycerin preparations: additive vasodilatory effect leading to severe blood pressure fall.

Moderate Interactions (Monitor Closely): - Antihypertensive agents (beta‑blockers, ACE inhibitors): may enhance blood pressure‑lowering effect. - Diuretics: can increase risk of orthostatic hypotension. - Alcohol: may potentiate vasodilatory response and dizziness.
