Lenitral Injectable (Glyceryl Trinitrate)

Glyceryl trinitrate, the active ingredient in Lenitral Injectable, is an organic nitrate presented as an injectable solution for intravenous use. It is employed to manage acute coronary syndrome, angina pectoris, heart failure, and hypertensive emergencies in hospital settings. It provides rapid relief of myocardial ischemia and assists blood pressure control in emergency care.

GNH USA supplies Lenitral Injectable as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide. The company adheres to stringent quality standards and provides regulatory‑approved batches for clinical use across multiple regions.

Lenitral Injectable (glyceryl trinitrate) acts within the cardiovascular emergency pathway to relieve myocardial ischemia and reduce cardiac workload. - Acute coronary syndrome: provides rapid vasodilation to improve coronary blood flow and lower myocardial oxygen demand. - Angina pectoris: relieves chest pain by decreasing preload and afterload. - Heart failure: reduces ventricular filling pressures and eases pulmonary congestion. - Hypertensive emergencies: lowers systemic vascular resistance for prompt blood pressure control.

Common Side Effects: - Headache: throbbing pain due to cerebral vasodilation. - Hypotension: transient drop in blood pressure, especially with rapid infusion. - Flushing: warm sensation and reddening of skin. - Tachycardia: compensatory increase in heart rate. - Dizziness or light‑headedness. - Nausea or vomiting.

Serious or Rare Side Effects: - Severe hypotension leading to syncope. - Paradoxical myocardial ischemia. - Methemoglobinemia. - Anaphylactoid or allergic reactions. - Life‑threatening arrhythmias. - Cardiogenic shock in susceptible patients.

Before use, clinicians should consider the following precautions: - Assess blood pressure before administration: monitor for excessive hypotension. - Avoid concurrent use with phosphodiesterase‑5 inhibitors: risk of profound vasodilation. - Use with caution in severe anemia: may worsen tissue hypoxia. - Monitor for tolerance development: consider drug‑free intervals to maintain efficacy. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Glyceryl trinitrate may interact with several drug classes.

Major Interactions (Avoid): - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): additive vasodilation causing severe hypotension. - Other nitrates (e.g., isosorbide dinitrate): risk of profound blood pressure fall. - Potent antihypertensives (e.g., hydralazine): may cause excessive hypotension.

Moderate Interactions (Monitor Closely): - Beta‑blockers: may mask tachycardic response to hypotension. - Calcium channel blockers: can enhance hypotensive effect. - Diuretics: may increase risk of volume depletion and orthostatic changes.
