Pharma Technology Innovation in Microsphere Formulation Processes

| Author/ Editor: Vaibhav Dalvi / Dominik Stephan

The Microsphere Refiner technology has been developed to address the growing demand for Microsphere formulation production – It also helps users to greatly reduce cost by using one piece of equipment instead of several process systems and sterile containment isolator.

New drug delivery devices such as PLA, PLGA or PMMA capsules have revolutionary applications. These biodegradable particles work as miniature time release capsules for parenteral drugs, to treat various conditions from cancer to diabetes and mental illness.

Microsphere production is experiencing a fast growing demand owing to its ground-breaking characteristics and applications including vaccines and hormones.

The Microsphere Refiner technology has been developed to address the growing demand for Microsphere formulation production. The existing process

caused manufacturing issues impacting the drug quality.

Too Big? To Small? Just Right!

When producing Microspheres, pharmaceutical manufacturers need to classify the particles per size to only retain specific sizes for the final products. The particles must be between 5–25 μm up to 150 μm.

Too small or too large particles will not have the desired effect once injected in the blood stream. The Microspheres need to be then washed from the solvent and dry under restricted conditions and recovered. All these processes require sterile handling.

The existing process could not guarantee the correct size distribution, the sterility and acceptable yield. By working with end users, PSL developed a unique equipment that is able to perform all the required process steps (filtration, washing, classification, drying and sterile recovery).
