PowdAir, a simple capsule based inhaler

PowdAir is a simple, easy to use, capsule based dry powder inhaler with excellent performance.


A simple, easy to use and efficient capsule-based dry powder inhaler with high performance.

In 2010, Hovione decided to develop a reusable, capsule based, low cost dry powder inhaler to deliver large drug doses.

PowdAir can deliver lactose-based or particle-engineered powders, and Hovione has effective experience in both types of formulations, from proof of concept, to optimization, robustness and compatibility tests, scale-up, method validation, stability studies and clinical supplies.


Effective delivery - Model Formulation

The minimum flow rate at which PowdAir has been shown to deliver 95% of the nominal dose is 30 liters per minute of airflow. Above 30 liters per minute, performance is unaffected.

Drug payloads range from the microgram range, employing lactose based formulations.


Comprehensive Intellectual Property Position

PowdAir is a patent protected device filed and granted in over 40 countries, including US (US 8677992) and EU (EP 2546460). In addition, other patents have been filed to cover additional scientific matter and the examination process is presently ongoing.
