1. WHAT NOXAP IS AND WHAT IS IT IS USED FOR
NOXAP is a gas mixture for inhalation use.
NOXAP is a medicinal gas, compressed, consisting of a mixture of gases that contains 800 ppm mol/mol
of nitric oxide.
What are its uses?
NOXAP must be administered exclusively by healthcare professionals and it is only for strict hospital use
NOXAP is indicated in the following conditions:
1. In newborns with a shortage of oxygen in the blood (hypoxemic respiratory failure) related to
different causes. NOXAP improves oxygenation and reduces the need for extracorporeal circulation.
2. In pediatric and adult cardiac surgery patients with acute high blood pressure within the lung
(pulmonary hypertension). NOXAP reduces the high blood pressure in the lung and reduces the risk of
failure of the right heart.
2. WHAT YOU NEED TO KNOW BEFORE YOU ARE GIVEN NOXAP
Do not use NOXAP in the following situations :
- Newborns with known dependency to right-left blood shunt or suffer from a significant left-right
- Patients with congenital or acquired deficiency of methemoglobin reductase (MetHb reductase) or
glucose 6 phosphate dehydrogenase (G6PD).
Take special care with NOXAP:
- In patients with left ventricular dysfunction, NOXAP could lead to cardiac insufficiency and
- In patients with complex congenital heart defects.
Using other medicines
Please tell your doctor if you are taking or have recently taken any other medicines, including medicines
obtained without a prescription.
Oxygen: In the presence of oxygen, nitric oxide oxidises rapidly producing substances that are toxic
for the lungs. To avoid this situation, continuous monitoring will be undertaken during NOXAP
NO donors: Cardiologic medicines such as Sodium Nitroprusside and Nitroglycerine, can have an
additive effect to NOXAP increasing the risk of developing methemoglobinemia.
Drugs that increase methemoglobin concentrations: When drugs such as alkyl nitrates, sulphonamides
and prilocaine are administrated along with nitric oxide there is increased risk of methemoglobinemia.
Synergic effects have been reported with the administration of vasoconstrictors (almitrine,
phenylephrine), prostacyclin and phosphodiesterase inhibitors, without increasing adverse effects.
Inhaled nitric oxide has been used concomitantly with tolazoline, dopamine, dobutamine,
norepinephrine, steroids and surfactants, with no drug interactions observed.
The doctor will decide if NOXAP can be used with other medications and will closely monitor your
Pregnancy and breast-feeding
NOXAP should not be used during pregnancy unless the clinical condition of the woman requires
treatment with NOXAP.
Harmful effects may be expected as methemoglobin is considered detrimental to the foetus and nitric
oxide has shown genotoxic potential by inducing structural alterations on DNA.
Breastfeeding should be discontinued during treatment with NOXAP.
Driving and using machines
Adverse effects on the ability to drive and use machines have not been communicated.
HOW NOXAP IS GIVEN
NOXAP must be administered exclusively by healthcare professionals and it is only for strict hospital use.
NOXAP is administered via inhalation which relies on a system that provides the lungs with the
prescribed nitric oxide concentration by diluting NOXAP in a mixture of oxygen and air.
Your doctor will determine the dosage and duration of your NOXAP treatment.
If you receive more NOXAP than you should the delivery system will activate a warning signal. Your
doctor will then reduce or stop the administration of NOXAP and subsequently will determine the most
suitable treatment to be followed.
If you stop receiving NOXAP
Your doctor will gradually reduce your NOXAP dosage towards the end of the treatment.
NOXAP treatment should not be abruptly interrupted but slowly reduced and so allow the lungs to adapt
to the normal oxygen concentration in the air.
If you have any further questions on the use of this product, ask your doctor or other health professionals.
POSSIBLE SIDE EFFECTS
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Your doctor will notice and closely monitor any side effects. It is not likely that you will experience these
side effects yourself.
Blood system disorders
elevated concentration of nitric oxide in the blood may run the risk of developing
methemogobinemia. In this case, blood oxygen transport capacity may be reduced. If this occurs, your
doctor will immediately reduce the nitric oxide dosage to allow the blood to achieve its normal
oxygen transport capacity. In pediatric patients and other with reduced levels of the enzyme,
methemoglobin reductase, this risk may increase. The formation of methemoglobin at a serum level of
>5% with inhaled nitric oxide at a concentrations of <20ppm is very rare (<1/10,000)
- Bleeding time: In a preclinical study has been found that inhaled nitric oxide increases the bleeding
time. However, in controlled clinical trials no significant differences have been found between the
control group and the treatment group regarding hemorrhagic complications.
General disorders and administration site conditions
- No response to the treatment can be observed in 30 to 45% of the cases.
- Significant elevations of NO2 levels at low therapeutic doses (<20 ppm) of inhaled NO, as well as
evidence of clinical toxicity by NO2 is a very rare (<1/10,000) complication.
- Abrupt interruption of the inhaled nitric oxide therapy, leads very frequently (>1/10) to rapid rebound
reactions presenting with intensified pulmonary vasoconstriction and hypoxemia. .
If any of the side effects become serious, or if you notice any side effects not listed in this leaflet, please
tell your doctor or other healthcare professionals.
Reporting of side effects
If you get any side effects, talk to your doctor or pharmacist. This includes any possible side effects not
listed in this leaflet. You can also report side effects directly via the national reporting system listed in
Appendix V*. By reporting side effects you can help provide more information on the safety of this
