Adaptive Aerosol Delivery (AAD) technology

Expert Opin Drug Deliv. 2004 Nov;1(1):165-76. doi: 10.1517/17425247.1.1.165.


Jet nebulisers have, since the 1920s, been used for delivery of inhaled drugs for the treatment of asthma, chronic-obstructive pulmonary disease and pulmonary infections. During the last two decades, recognition of the shortcomings of conventional nebulisers has led to the development of new "intelligent" nebulisers such as the Adaptive Aerosol Delivery (AAD), Profile Therapeutics, a Respironics company) systems. Diseases of the airways have traditionally been logical candidates for treatment with inhaled drugs. The introduction of the "intelligent" nebulisers has, however, broadened the possibilities for inhaled treatment to include drugs targeted for systemic diseases. These nebulisers offer the possibility to deliver more precise doses of drug, maximise lung deposition, enhance adherence to treatment and compliance with the device through feedback to the patient, and last but not least, offer the possibility to reduce nebulisation times.
