Nitroglicerina Zentiva (Glyceryl Trinitrate)

Glyceryl Trinitrate, the active ingredient in Nitroglicerina Zentiva, is a organic nitrate presented as a transdermal patch for transdermal use. It treats angina pectoris, acute coronary syndromes and heart failure in adult patients.

GNH USA supplies Nitroglicerina Zentiva as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Nitroglicerina Zentiva, an organic nitrate used in cardiovascular therapy, is indicated for: - Angina pectoris: provides rapid relief of chest pain by reducing myocardial oxygen demand. - Acute coronary syndromes: helps prevent ischemic events through sustained vasodilation. - Heart failure: improves symptoms by decreasing preload and afterload.

Nitroglicerina Zentiva may cause a range of adverse reactions.

Common Side Effects: - Headache: throbbing pain often occurring shortly after application. - Dizziness or light‑headedness: due to lowered blood pressure. - Flushing: warm sensation and reddening of the skin. - Skin irritation at the patch site: erythema or itching. - Tachycardia: compensatory increase in heart rate. - Hypotension: mild drop in blood pressure.

Serious or Rare Side Effects: - Severe hypotension: marked blood pressure fall requiring medical intervention. - Syncope: sudden loss of consciousness. - Myocardial infarction: rare worsening of cardiac ischemia. - Severe allergic reaction: rash, swelling, or breathing difficulty. - Methemoglobinemia: abnormal hemoglobin affecting oxygen transport. - Skin necrosis: rare severe tissue damage at the application site.

Before using Nitroglicerina Zentiva, consider the following precautions: - Cardiovascular assessment: evaluate blood pressure and cardiac status. - Avoid in severe anemia: reduced oxygen‑carrying capacity may worsen symptoms. - Use with caution in hypotension: monitor for excessive blood‑pressure decline. - Monitor for tolerance development: effectiveness may diminish over time. - Contraindicated with phosphodiesterase‑5 inhibitors: risk of profound hypotension. - Store at room temperature below 25°C: keep in the original pack, protect from moisture and direct sunlight.

Nitroglicerina Zentiva can interact with several medicines.

Major Interactions (Avoid): - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): may cause severe hypotension. - Other nitrates (e.g., isosorbide dinitrate): additive vasodilatory effect. - Potent antihypertensives (e.g., clonidine): risk of excessive blood‑pressure drop.

Moderate Interactions (Monitor Closely): - Alcohol: can enhance vasodilatory response. - Beta‑blockers: may mask tachycardia signs. - Diuretics: may increase the likelihood of hypotension.
