Nitrofix (Glyceryl Trinitrate)

Glyceryl Trinitrate, the active ingredient in Nitrofix, is a nitrate vasodilator presented as a transdermal patch for transdermal use. It reduces myocardial oxygen demand by dilating veins and arteries, making it useful in the management of angina pectoris, acute coronary syndrome and as an adjunct in heart failure.

GNH USA supplies Nitrofix as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to EU quality standards and provides regulatory documentation to support import and distribution.

Nitrofix (glyceryl trinitrate) acts on the nitrate pathway to relieve myocardial ischemia.

- Angina pectoris: reduces frequency and severity of chest pain by decreasing cardiac workload. - Acute coronary syndrome: improves coronary blood flow and limits ischemic injury during episodes. - Heart failure (adjunct therapy): lowers preload and myocardial oxygen consumption, supporting symptomatic management.

Nitrofix 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: due to lowered blood pressure. - Hypotension: noticeable drop in blood pressure, especially upon standing.

Serious or Rare Side Effects: - Methemoglobinemia: abnormal hemoglobin affecting oxygen transport. - Severe hypotension with syncope: sudden drop in blood pressure leading to fainting.

Before prescribing Nitrofix, clinicians should consider several safety measures and patient‑specific factors. - Cardiovascular assessment: evaluate for recent myocardial infarction or severe aortic stenosis. - Concomitant nitrate therapy: avoid combined use to prevent excessive hypotension. - Phosphodiesterase‑5 inhibitors: contraindicated due to risk of profound vasodilation. - Blood pressure monitoring: check baseline and orthostatic readings. - Store at room temperature: keep below 25°C in original packaging, protect from moisture and direct sunlight.

Nitrofix interacts with several drug classes that can modify its vasodilatory effect or increase toxicity.

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 fall. - Guanylate cyclase stimulators: increase risk of hypotension.

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