What is Nitric Oxide?
Nitric oxide, the active ingredient in Monoxid De Azot Messer, is a vasodilator presented as a medical gas for inhalation use. It is employed to manage neonatal pulmonary hypertension, acute respiratory distress syndrome, and pulmonary hypertension in appropriate patient populations.
GNH USA supplies Monoxid De Azot Messer as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.
What is Nitric Oxide used for?
Monoxid De Azot Messer is a pulmonary vasodilator used in conditions affecting the pulmonary circulation.
Neonatal pulmonary hypertension: reduces pulmonary arterial pressure and improves oxygenation in newborns. Acute respiratory distress syndrome: lowers pulmonary vascular resistance to support gas exchange. Pulmonary hypertension: provides selective pulmonary vasodilation to alleviate symptoms and improve functional capacity.
What are the side effects of Nitric Oxide?
Nitric oxide inhalation can be associated with a range of adverse reactions.
Common Side Effects: - Headache - Dizziness - Flushing - Cough or throat irritation - Nausea - Transient hypotension
Serious or Rare Side Effects: - Severe hypotension - Methemoglobinemia - Pulmonary edema - Bronchospasm - Allergic reactions (rash, anaphylaxis) - Respiratory failure
What precautions apply to Nitric Oxide?
Use of inhaled nitric oxide requires careful clinical monitoring.
Monitor hemodynamics: observe blood pressure and oxygenation continuously. Controlled setting: administer only in facilities equipped for respiratory support. Avoid in severe anemia: risk of methemoglobinemia may be increased. Caution with PDE5 inhibitors: additive vasodilatory effect can cause profound hypotension. Pregnancy safety unknown: use only if clearly indicated and benefits outweigh risks. Store at ambient temperature: keep cylinders upright, protect from heat and direct sunlight.
What does Nitric Oxide interact with?
Nitric oxide may interact with other agents that affect vascular tone or blood gases.
Major Interactions (Avoid): - Phosphodiesterase‑5 inhibitors (e.g., sildenafil) – risk of excessive hypotension. - Sodium nitroprusside – additive vasodilatory effect. - Other inhaled pulmonary vasodilators – may cause severe hypotension.
Moderate Interactions (Monitor Closely): - Inhaled anesthetics – may potentiate respiratory depression. - Systemic vasodilators – require blood pressure monitoring.
