Nitrocor (Glyceryl Trinitrate)

Glyceryl trinitrate, the active ingredient in Nitrocor, is a nitrate vasodilator presented as a sublingual tablet for sublingual use. It provides rapid relief of angina pectoris and is employed in patients with coronary artery disease to alleviate myocardial ischemia.

GNH USA supplies Nitrocor as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to EU GMP standards and provides reliable cold‑chain logistics where required, ensuring product integrity from manufacturing to end‑user and timely delivery.

Nitrocor (glyceryl trinitrate) is a nitrate vasodilator used in the management of coronary artery disease and related angina syndromes.

Acute angina pectoris: provides rapid relief of chest pain during an attack. Prophylaxis of angina: reduces the frequency of angina episodes when taken before exertion. Heart failure (adjunct): assists in reducing preload and afterload as part of combination therapy.

Glyceryl trinitrate may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Headache: throbbing pain often triggered by vasodilation. - Flushing: warmth and redness of the skin. - Dizziness or light‑headedness. - Low blood pressure (orthostatic hypotension).

Serious or Rare Side Effects: - Severe hypotension leading to fainting. - Syncope (sudden loss of consciousness). - Allergic reactions including rash or anaphylaxis. - Methemoglobinemia: abnormal hemoglobin causing cyanosis.

When prescribing Nitrocor, clinicians should consider several safety precautions to minimize risk. - Cardiovascular status: avoid in patients with severe hypotension or recent myocardial infarction. - Concomitant nitrates: do not combine with other nitrate preparations to prevent additive hypotension. - Phosphodiesterase‑5 inhibitors: contraindicated due to risk of profound hypotension. - Use in elderly: monitor blood pressure closely as sensitivity may be increased. - Pregnancy and lactation: use only if potential benefit justifies risk; data limited. - Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture and light.

Nitrocor can interact with several drug classes, altering its efficacy or safety profile.

Major Interactions (Avoid): - Other nitrates or nitric oxide donors: additive vasodilatory effect causing severe hypotension. - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): risk of profound hypotension. - Guanylate cyclase stimulators: may amplify vasodilation.

Moderate Interactions (Monitor Closely): - Antihypertensives (beta‑blockers, ACE inhibitors): may enhance blood pressure lowering. - Diuretics: can increase risk of orthostatic hypotension. - Alcohol: may potentiate vasodilatory effects.
