Microsphere is a CDMO focused on new developments, cGMP manufacturing, R&D and analytical services with a deep focus on inhalation. Founded in 1998, we have a long track record in overcoming complex formulation challenges and taking products from development batches to commercial phase. We address complex challenges on formulations, with extensive expertise in Spray Drying and Capsule Filling.
Microsphere’s expertise on powder comes from strong technical know-how in preparing a multitude of liquid feedstock for spray drying at optimum process conditions to obtain particles with morphologies especially adapted to inhalation, leveraging also the internal capabilities on advanced solid-state characterization and tests that can be performed in-house.
Our spray drying technologies offer unrivaled service to our partners, turning standards into value and assets, using only the best-in-class spray dryers and without limitations on solvents (aqueous and organic). We can handle APIs, HPAPIs and other compounds.
Microsphere has a global portfolio of customers and it is recognized as a trusted partner: from development to manufacturing, pharmaceutical companies can rely on science-led solutions, leveraging Microsphere’s extensive expertise in Particle Engineering.
The facility is also equipped with low humidity areas for filling and testing for aerodynamic performances. Microsphere’s Swiss facility is approved and regularly inspected by EU GMP, SwissMedic, US FDA and PMDA. Microsphere is registered by the FDA as a FDF (Finished Dosage Facility).
