Solid State chemistry

The solid-state chemistry of an active pharmaceutical ingredient (API) is a fundamental aspect to be considered in the Final Dosage Form (FDF), in particular with respect to the morphology, crystalline form and the particle size distribution, as it can dramatically affect bioavailability.

The experts at the Axplora Solid State Center of Excellence support specific customer requests regarding the physical properties of their products.
