Inhanimon

Nitric Oxide, the active ingredient in Inhanimon, is a vasodilator presented as a gas for inhalation use. It relaxes smooth muscle in the pulmonary vasculature and improves ventilation‑perfusion matching in patients with respiratory and cardiovascular conditions.

GNH USA supplies Inhanimon as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies and clinics worldwide.

Inhanimon delivers inhaled nitric oxide, targeting the pulmonary vasculature and respiratory pathways. - Pulmonary arterial hypertension: reduces pulmonary artery pressure and improves oxygenation. - Neonatal persistent pulmonary hypertension: facilitates transition to normal pulmonary circulation. - Acute respiratory distress syndrome (ARDS): enhances ventilation‑perfusion matching and oxygen delivery. - Post‑cardiac surgery pulmonary hypertension: supports hemodynamic stability. - Severe hypoxic respiratory failure: provides temporary oxygenation support.

Inhaled nitric oxide may be associated with a range of adverse reactions, varying in frequency and severity.

Common Side Effects: - Headache: mild to moderate headache due to cerebral vasodilation. - Flushing: transient warmth and redness of the skin. - Nausea: occasional feeling of queasiness. - Dizziness: light‑headed sensation during therapy. - Cough: irritation of airways from gas delivery.

Serious or Rare Side Effects: - Methemoglobinemia: elevated methemoglobin levels reducing oxygen transport. - Nitrogen dioxide formation: inhalation of NO₂ leading to pulmonary irritation. - Hypotension: systemic blood pressure drop if high doses are absorbed. - Bleeding: increased risk of hemorrhage in patients on anticoagulants.

When prescribing inhaled nitric oxide, clinicians should consider several safety measures. - Dose titration: adjust concentration based on patient response and monitoring. - Monitoring: regularly assess methemoglobin and nitrogen dioxide levels during therapy. - Contraindications: avoid in patients with known hypersensitivity to nitric oxide. - Drug interactions: review concurrent use of phosphodiesterase inhibitors and anticoagulants. - Pregnancy and lactation: use only if benefits outweigh potential risks. - Store at room temperature: keep cylinders in original packaging, protect from heat and direct sunlight.

Inhaled nitric oxide can interact with other agents that affect the nitric oxide pathway or blood coagulation.

Major Interactions (Avoid): - Sildenafil or other PDE‑5 inhibitors: additive vasodilatory effect may cause severe hypotension. - Methylene blue: can reverse nitric oxide effects and precipitate methemoglobinemia. - High‑dose inhaled NO with systemic vasodilators: risk of systemic hypotension.

Moderate Interactions (Monitor Closely): - Anticoagulants (warfarin, heparin): increased bleeding risk when methemoglobinemia occurs. - Bronchodilators: may enhance airway reactivity. - Ventilator settings: adjust to prevent accumulation of nitrogen dioxide.
