pulmonary delivery system(redirected from inhalation delivery system)
pulmonary delivery systemA system designed for noninvasive, systemic delivery of therapeutic macromolecules (e.g., insulin, tobramycin, leuprolide, dronabinol, PTH) via alveolar absorption.
Pulmonary route offers the highest bioavailability of any noninvasive route and facilitates more rapid drug absorption in the circulation compared with subcutaneous injection.
Administration of insulin, the pilot for the pulmonary delivery platform, resulted in inconsistent serum levels. It proved too expensive for the market.
