A Massachusetts engineering firm called Enginasion has disclosed details of proprietary DPI-filling technology it says that it developed for a pharmaceutical client that needed accurate dispensing of a highly cohesive inhaled dry powder formulation into cartridges. Enginasion Founder and CEO David Bonneau is the co-author of several patents assigned to MannKind Corporation that describe a dispensing system for MannKind’s Technosphere dry powder formulations.
Bonneau describes the system as using 48 microbalances for 50 mcg dispensing accuracy and 100% inspection within a cubic foot of space. He claims that “For the first time, every single dosage can be inspected to ensure the dispensing of the precise amount of dry powder.”
