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 in Axplora Solid State Center of Excellence support specific customer’s requests in terms of physical properties of their products.
