Indications and Usage for Inomax

Inomax® is indicated to improve oxygenation and reduce the need for extracorporeal membrane oxygenation in term and near-term (>34 weeks gestation) neonates with hypoxic respiratory failure associated with clinical or echocardiographic evidence of pulmonary hypertension in conjunction with ventilatory support and other appropriate agents.

Inomax Dosage and Administration


Term and near-term neonates with hypoxic respiratory failure

The recommended dose of Inomax is 20 ppm. Maintain treatment up to 14 days or until the underlying oxygen desaturation has resolved and the neonate is ready to be weaned from Inomax therapy.

Doses greater than 20 ppm are not recommended [see Warnings and Precautions (5.2)].


Training in Administration

The user of Inomax and Nitric Oxide Delivery Systems must satisfactorily complete a comprehensive periodic training program for health care professionals provided by the delivery system and drug manufacturers. Health professional staff that administers nitric oxide therapy have access to supplier-provided 24 hour/365 days per year technical support on the delivery and administration of Inomax at 1-877-566-9466.

Nitric Oxide Delivery Systems

Inomax must be administered using a calibrated Inomax DSIR® Nitric Oxide Delivery System. Only validated ventilator systems should be used in conjunction with Inomax. Consult the Nitric Oxide Delivery System label or call 1-877-566-9466/visit for a current list of validated systems.

Keep available a backup battery power supply and an independent reserve nitric oxide delivery system to address power and system failures.


Measure methemoglobin within 4-8 hours after initiation of treatment with Inomax and periodically throughout treatment [see Warnings and Precautions (5.2)].

Monitor for PaO2 and inspired NO2 during Inomax administration [see Warnings and Precautions 5.3)].

Weaning and Discontinuation

Avoid abrupt discontinuation of Inomax [see Warnings and Precautions (5.1)]. To wean Inomax, downtitrate in several steps, pausing several hours at each step to monitor for hypoxemia.

Dosage Forms and Strengths

Inomax (nitric oxide) gas is available in a 800 ppm concentration.


Inomax is contraindicated in neonates dependent on right-to-left shunting of blood.

Inomax Description

Inomax (nitric oxide gas) is a drug administered by inhalation. Nitric oxide, the active substance in Inomax, is a pulmonary vasodilator. Inomax is a gaseous blend of nitric oxide and nitrogen (0.08% and 99.92%, respectively for 800 ppm). Inomax is supplied in aluminum cylinders as a compressed gas under high pressure (2000 pounds per square inch gauge [psig]).

The structural formula of nitric oxide (NO) is shown below:
