Nitroglycerine Teva (Glyceryl Trinitrate)

Glyceryl trinitrate, the active ingredient in Nitroglycerine Teva, is a nitrate vasodilator presented as a cutaneous formulation for transdermal use. It reduces myocardial oxygen demand by causing vasodilation of coronary arteries and is employed to relieve chest pain and improve coronary blood flow in patients with angina, acute coronary syndromes, and certain forms of heart failure.

GNH USA supplies Nitroglycerine Teva as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, ensuring consistent quality and regulatory compliance across markets.

Nitroglycerine Teva acts on the cardiovascular system to alleviate ischemic chest pain and improve coronary perfusion.

- Angina pectoris: provides rapid relief of chest pain by increasing coronary blood flow. - Acute coronary syndrome: lowers myocardial oxygen demand and supports hemodynamic stability. - Heart failure (adjunctive therapy): reduces preload and afterload, aiding symptom control.

Nitroglycerine Teva may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Headache: throbbing pain often occurring shortly after application. - Dizziness or light‑headedness: related to blood pressure reduction. - Flushing: warm sensation and reddening of skin. - Hypotension: measurable drop in blood pressure. - Tachycardia: compensatory increase in heart rate. - Nausea: occasional gastrointestinal upset.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure requiring medical attention. - Syncope: fainting episodes due to inadequate cerebral perfusion. - Myocardial infarction: rare but possible in susceptible patients. - Allergic reaction: skin rash, itching, or swelling. - Methemoglobinemia: abnormal hemoglobin causing cyanosis. - Life‑threatening arrhythmias: irregular heart rhythms.

Before using Nitroglycerine Teva, consider the following safety measures.

- Monitor blood pressure: check for excessive hypotension, especially after the first dose. - Avoid concurrent nitrates: combined use can cause profound vasodilation. - Caution with PDE‑5 inhibitors: risk of severe hypotension when used together. - Assess tolerance development: efficacy may diminish with continuous exposure. - Store at room temperature: keep in the original pack, protect from moisture and light.

Nitroglycerine Teva can interact with several drug classes; awareness helps prevent adverse events.

Major Interactions (Avoid): - Other nitrates (e.g., isosorbide dinitrate): additive vasodilatory effect. - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): risk of profound hypotension. - Alpha‑adrenergic blockers (e.g., prazosin): may cause severe blood pressure drops. - Antihypertensive agents (especially combined therapy): increased hypotensive risk. - Riociguat: synergistic vasodilatory action.

Moderate Interactions (Monitor Closely): - Diuretics: may enhance blood pressure lowering. - Beta‑blockers: can mask tachycardia response. - Alcohol: additive vasodilatory effect, may increase dizziness.
