Microsphere formulation

The MicroSphere Refiner (MSR™) is the flagship process technology of Powder Systems Ltd (PSL). It is disrupting the way microsphere drugs are traditionally developed and manufactured around the world.

Microspheres or micro-particles are complex drug formulations combining an Active Pharmaceutical Ingredient (API) with an FDA-approved polymer such as PLGA. Microsphere drugs enable the sustained release of APIs into patients over prolonged periods of time, varying from weeks up to several months.
