About the I-neb AAD System

The I-neb AAD System is a battery-powered pulmonary drug delivery system that makes it possible for patients to take their Ventavis® (iloprost) Inhalation Solution treatments almost anywhere. With up to 40 treatments from a single charge, the I-neb AAD System frees patients from the need to be near an electrical outlet. Because the I-neb AAD System is portable and virtually silent, patients may find it easier to comply with their prescribed dosing regimen. Finally, with Adaptive Aerosol Delivery (AAD) technology, you can be sure that your patients are receiving an accurate dose.

Use the I-neb AAD System to dispense Ventavis. Standard air-jet nebulizers/compressors or ultrasonic nebulizer systems, such as those used to deliver inhalation solutions for asthma, are continuous flow systems that constantly generate aerosol. Patients typically have a 40:60 inhalation:exhalation ratio; therefore, about 60% of the drug is wasted to the environment with such devices during exhalation.1 Additionally, a variable amount of drug is inhaled by each patient because individual breathing patterns differ (e.g., short, shallow breaths to long, deep breaths).

Specifically designed for use with Ventavis

Variable dosing is acceptable for drugs with a broad therapeutic window (e.g., albuterol and ipratropium bromide); however, Ventavis is a potent prostacyclin analogue with a narrow therapeutic index. Precise, reproducible dosing of Ventavis to every patient is required for the safety and efficacy of the drug.

Delivers precise doses to every patient

The system uses AAD technology to precisely and reproducibly deliver Ventavis to every patient, at either dose (2.5 mcg or 5.0 mcg), using a single ampule of medication. The dose each patient receives is controlled by the medication chamber. The I-neb AAD System continuously monitors and analyzes a patient's breathing pattern and delivers pulses of aerosol into the start of each inhalation until the set dose is delivered.

One ampule per treatment

Only one drug treatment (either 2.5 mcg or 5.0 mcg) can be delivered from the contents of a single ampule. Reuse of any drug solution that remains after completing a drug treatment, even if the reservoir is "topped off" with fresh medication, will not give accurate dosing. Do not reuse ampules.
