NOXAP is a gas mixture for inhalation use.

NOXAP is a medicinal gas, compressed, consisting of a mixture of gases containing 200 ppm mol/mol of nitrogen oxide.

What are its uses?

NOXAP must be administered exclusively by healthcare professionals and is only for strictly hospital use. NOXAP is indicated in the following cases:

In newborns with a lack of oxygen in the blood (hypoxemic respiratory insufficiency) related to different causes.

NOXAP improves oxygenation and reduces the need for circulation

In pediatric and adult patients undergoing cardiac surgery with acute high blood pressure in the lungs (pulmonary hypertension). NOXAP reduces pulmonary hypertension and the risk of right heart failure.

Do not take NOXAP in the following cases:

• Infants with proven dependency on right-to-left shunt or those suffering from significant left-to-right shunt.
• Patients with congenital or acquired deficiency of methemoglobin reductase (MetHb reductase) or glucose 6 phosphate dehydrogenase (G6PD).

Be especially cautious with NOXAP:

• In patients with left ventricular dysfunction, NOXAP may cause heart failure and pulmonary edema.
• In patients with complex congenital heart defects.

Use of other medications

Inform your doctor if you are using or have recently used other medications, including those obtained without a prescription.

Oxygen:In the presence of oxygen, nitric oxide oxidizes rapidly, producing substances that are toxic to the lungs. To avoid this situation, continuous monitoring must be performed during treatment with NOXAP.

NO donors:Cardiological medications such as sodium nitroprusside and nitroglycerin may have an additive effect to that of NOXAP, increasing the risk of presenting methemoglobinemia.

Medications that increase methemoglobin concentrations: When medications such as alkyl nitrates, sulfonamides, and prilocaine are administered with nitric oxide, there is an increased risk of presenting methemoglobinemia.

Synergistic effects have been reported with the administration of vasoconstrictors (almitrine, phenylephrine), prostacyclin, and phosphodiesterase inhibitors, without increasing adverse reactions.

Inhaled nitric oxide has been used at the same time as tolazoline, dopamine, dobutamine, norepinephrine, steroids, and surfactants, without observing interactions.

The doctor will decide if NOXAP can be used with other medications and will closely monitor treatment.

Pregnancy and breastfeeding

NOXAP should not be used during pregnancyunless the patient's clinical condition requires treatment with NOXAP.

Adverse effects may be expected since methemoglobin is considered harmful to the fetus and nitric oxide has demonstrated a genotoxic potential by inducing structural alterations in DNA.

Breastfeeding should be interrupted during treatment with NOXAP.

Driving and operating machinery

No studies have been reported on the ability to drive and operate machinery.

NOXAP must be administered exclusively by healthcare professionals and is only for strictly hospital use.

NOXAP is administered via inhalation through a system that delivers the prescribed concentration of nitric oxide to the lungs by diluting NOXAP in a mixture of oxygen and air.

Your doctor will determine the dosage and duration of your treatment with NOXAP.

If you take more NOXAP than you should,The administration system will activate a warning signal. Your doctor will then reduce or stop the administration of NOXAP and subsequently determine the most suitable treatment to follow.

If you interrupt treatment with NOXAP

Your doctor will gradually reduce the dosage of NOXAP until the end of treatment.

Treatment with NOXAP should not be interrupted abruptly, but rather reduced slowly to allow the lungs to adapt to the normal oxygen concentration in the air.

If you have any other questions about the use of this product, ask your doctor or other healthcare personnel.

Like all medications, NOXAP may have adverse effects, although not everyone will experience them.

Your doctor will closely monitor and watch for any adverse effects. It is unlikely that you will suffer from these adverse effects.

Blood and Lymphatic System Disorders

• An increase in nitric oxide concentration in the blood may lead to the risk of developing methemoglobinemia. In this case, the blood's ability to transport oxygen may decrease. If this occurs, your doctor will immediately reduce the dosage of nitric oxide to allow the blood to reach its normal oxygen transport capacity. In pediatric patients and others with reduced levels of methemoglobin reductase enzyme, this risk may increase. The formation of methemoglobin with a serum level of >5% with inhaled nitric oxide concentrations of <20>
• Bleeding Time:In a preclinical study, it was observed that inhaled nitric oxide increased bleeding time. However, in controlled clinical studies that have been conducted, no significant differences were found between the control group and the treatment group regarding hemorrhagic complications.

General Disorders and Administration Site Conditions

• A lack of response to treatment may be observed in 30 to 45% of cases.
• A significant increase in NO2 concentrations at therapeutic doses (<20 ppm) of inhaled no, with evidence clinical toxicity by no2, is a very rare complication (<1 10,000).< span>
• Abrupt interruption of treatment with inhaled nitric oxide causes frequent (>) reactions, which present an intensification of pulmonary vasoconstriction and hypoxemia.

Reporting of Adverse Effects

If you experience any type of adverse effect, consult your doctor or pharmacist, even if it is an adverse effect that does not appear in this prospectus. You can also report them directly through the Spanish System for Pharmacovigilance of Medicinal Products for Human Use:www.notificaRAM.es. By reporting adverse effects, you can contribute to providing more information on the safety of this medication.

Conservation in the medical department

Containers must be stored in a place with the necessary equipment to ensure they remain in an upright position.

Composition of NOXAP

NOXAP is a combination of gases.

• The active principle is: nitric oxide 200 ppm (mol/mol)
• The other component is: nitrogen.
