INOMAX® DS Drug-Delivery Systems Recalled

Ikaria, Inc. just announced that its <"">INOMAX® DS drug-delivery systems in the United States are being voluntarily recalled due to the potential failure of a pressure switch, which may have an impact on the administration of INOMAX® (nitric oxide) for inhalation to patients, announced the U.S. Food and Drug Administration (FDA).

The potential failure was identified by Ikaria as part of its ongoing quality monitoring and review processes. This Class I recall is being conducted with the knowledge of the FDA and all INOMAX DS systems in Canada also are being voluntarily recalled.

Specifically, a component within the pressure switch, which monitors when the drug supply should be replaced, may tear. In the event of a tear, the flow of INOMAX to the patient is not immediately interrupted. While the patient is not immediately impacted by the pressure leak, subsequent risks to the patient may include interruption of drug flow due to an empty cylinder, and/or the time taken to switch to a replacement system.

An interruption or delay in the administration of INOMAX therapy may cause:

• Worsening of systemic oxygenation indices (i.e., hypoxemia, especially manifested as decreased arterial oxygenation saturation);
• Hypotension; and/or
• An increase in pulmonary arterial pressure.

If a leak is suspected, clinicians should:

• Not interrupt the delivery of INOMAX;
• Verify an adequate amount of INOMAX remains in the cylinder;
• Switch to the manual back-up system using the INOblender® by connecting the INOMAX Inlet Hose of the INOblender directly to the INOMAX regulator, and follow the standard procedure for use of the INOblender as the primary back-up method for manual ventilation, and;
• Contact Ikaria Customer Care at 1-877-KNOW-INO (1-877-566-9466) for assistance.

Although the risk of INOMAX exposure to pregnant women is unknown, it is advised that healthcare professionals who may be pregnant avoid the immediate area in which a leak is suspected.

Ikaria has begun the replacement process of all INOMAX DS drug-delivery systems with remediated INOMAX DS systems. This recall does not apply to the INOvent® drug-delivery system.

Ikaria sent recall notices to healthcare professionals on July 21, 2010 informing them of this action and identifying steps intended to reduce potential risks associated with a system failure. These notices contain more detailed information about the device usage and are available at or
