Nitrocor (Glyceryl Trinitrate)

Glyceryl trinitrate, the active ingredient in Nitrocor, is an organic nitrate presented as a sublingual tablet for sublingual use. It treats acute angina pectoris, provides prophylaxis of angina episodes, and is used in selected cases of heart failure.

GNH USA supplies Nitrocor as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, with a focus on reliable quality and regulatory compliance.

Nitrocor (glyceryl trinitrate) is used in the anti‑anginal drug class to manage coronary ischemia.

- Acute angina pectoris: rapid relief of chest pain by dilating coronary vessels. - Prophylaxis of angina pectoris: reduces the frequency of angina attacks during exertion. - Heart failure: improves symptoms in patients with left ventricular dysfunction by decreasing preload and afterload.

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

Common Side Effects: - Headache: throbbing pain often occurring shortly after administration. - Flushing: warmth and redness of the face or neck. - Hypotension: transient drop in blood pressure causing dizziness. - Tachycardia: compensatory increase in heart rate. - Nausea: mild gastrointestinal discomfort.

Serious or Rare Side Effects: - Severe hypotension: marked blood pressure fall leading to syncope. - Methemoglobinemia: elevated methemoglobin causing cyanosis. - Allergic reaction: rash, itching, or swelling. - Chest pain rebound: worsening angina after nitrate tolerance. - Vision disturbances: blurred vision or photophobia.

When prescribing Nitrocor, clinicians should observe several safety considerations.

- Cardiovascular status: avoid in patients with severe hypotension or recent myocardial infarction. - Concomitant nitrate therapy: do not combine with other long‑acting nitrates to prevent additive hypotension. - Phosphodiesterase‑5 inhibitors: contraindicated due to risk of profound hypotension. - Pregnancy and lactation: use only if potential benefit outweighs unknown risks. - Driving and operating machinery: advise caution if dizziness occurs. - Store at below 25°C: keep in original container, protect from moisture and light.

Nitrocor interacts with several drug classes that can modify its hemodynamic effects.

Major Interactions (Avoid): - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): may cause severe hypotension. - Other nitrates or nitrites: additive vasodilatory effect leading to dangerous blood pressure drop. - Uncontrolled hypertension medications: may blunt therapeutic effect.

Moderate Interactions (Monitor Closely): - Antihypertensives (ACE inhibitors, ARBs, beta‑blockers): may enhance blood pressure lowering. - Diuretics: increase risk of volume depletion and hypotension. - Alcohol: can potentiate vasodilatory response. - Calcium channel blockers: may augment hypotensive effect.
