Inomax

Nitric Oxide, the active ingredient in Inomax, is a Vasodilator presented as a medical gas for endotracheopulmonary use. It is employed to manage pulmonary hypertension and neonatal persistent pulmonary hypertension by providing selective pulmonary vasodilation. GNH USA supplies Inomax as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

Inomax is a pulmonary vasodilator used in conditions affecting the pulmonary circulation. - Pulmonary hypertension: lowers pulmonary arterial pressure and improves oxygenation. - Neonatal persistent pulmonary hypertension: provides selective pulmonary vasodilation to enhance oxygen exchange in newborns.

Adverse reactions may occur with inhaled nitric oxide therapy.

Common Side Effects: - Methemoglobinemia: elevation of methemoglobin levels causing reduced oxygen delivery. - Nitrogen dioxide formation: irritant gas that can damage airway mucosa. - Transient systemic hypotension: mild drop in systemic blood pressure.

Serious or Rare Side Effects: - Severe methemoglobinemia: may require methylene blue treatment. - Rebound pulmonary hypertension: sudden rise in pulmonary pressure after abrupt discontinuation. - Significant nitrogen dioxide‑induced lung injury: can lead to respiratory distress.

Proper use of Inomax requires careful monitoring and specific safety measures. - Dose titration: adjust based on pulmonary artery pressure and oxygenation response. - Monitoring: continuous pulse‑oximetry and regular methemoglobin level checks are essential. - Anemia caution: avoid or use with caution in severe anemia due to increased methemoglobin risk. - Concomitant vasodilators: monitor for additive hypotensive effects. - Store at ambient temperature: keep cylinder in original packaging, protect from heat and direct sunlight.

Inomax can interact with several drug classes, necessitating vigilance.

Major Interactions (Avoid): - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): additive pulmonary vasodilation may cause severe hypotension. - Other nitric oxide donors: combined use increases risk of methemoglobinemia.

Moderate Interactions (Monitor Closely): - Inhaled anesthetics (e.g., nitrous oxide): may potentiate vasodilatory effect. - Systemic vasodilators (e.g., nitroglycerin): monitor blood pressure for additive drops. - Bronchodilators: observe for changes in airway reactivity.
