What is Glyceryl Trinitrate?
Glyceryl Trinitrate, the active ingredient in Nitroglycerin, is an organic nitrate vasodilator presented as a sterile intravenous solution for intravenous administration. It is used to relieve acute angina pectoris, manage heart failure, and treat hypertensive emergencies by rapidly dilating coronary and systemic vessels in adult patients.
GNH USA supplies Nitroglycerin as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, with reliable cold‑chain logistics for the IV product.
What is Glyceryl Trinitrate used for?
Nitroglycerin is an organic nitrate used in the management of acute cardiovascular conditions.
Acute angina pectoris: rapid relief of chest pain by improving myocardial oxygen supply. Heart failure: reduction of preload and afterload to enhance cardiac output. Hypertensive emergencies: prompt vasodilation to lower systemic blood pressure.
What are the side effects of Glyceryl Trinitrate?
Nitroglycerin may cause a range of adverse reactions, from frequent to serious.
Common Side Effects: - Headache: throbbing pain due to cerebral vasodilation. - Hypotension: transient drop in blood pressure, especially with rapid infusion. - Flushing: warmth and redness of the skin. - Tachycardia: compensatory increase in heart rate. - Dizziness or light‑headedness.
Serious or Rare Side Effects: - Severe hypotension leading to syncope. - Myocardial infarction in susceptible patients. - Methemoglobinemia causing impaired oxygen delivery. - Anaphylactic or severe allergic reaction. - Life‑threatening arrhythmias.
What precautions apply to Glyceryl Trinitrate?
Nitroglycerin requires careful monitoring and specific safety measures.
Monitor blood pressure: watch for excessive drops during infusion. Avoid concomitant nitrates or PDE5 inhibitors: risk of profound hypotension. Use cautiously in severe anemia or increased intracranial pressure. Adjust dose in elderly or renal‑impaired patients. Store at 2-8°C: keep refrigerated, protect from light, do not freeze.
What does Glyceryl Trinitrate interact with?
Nitroglycerin can interact with other cardiovascular agents, altering its safety profile.
Major Interactions (Avoid): - Other nitrates (e.g., isosorbide dinitrate): additive vasodilation. - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): risk of severe hypotension. - Guanylate cyclase stimulators: excessive vasodilatory effect.
Moderate Interactions (Monitor Closely): - Beta‑blockers: may blunt compensatory tachycardia. - Diuretics or ACE inhibitors: additive blood‑pressure lowering. - Calcium‑channel blockers: potential for enhanced hypotensive response.
