The primary objectives of solid state stability investigations are identification of stable storage conditions for drug product and identification of compatible excipients for the formulation. Solid state stability testing usually requires repetitive testing of the initial bulk lot in parallel with newer bulk lots, therefore adequate material should be set aside for these studies.
VxP Pharma offers solid state studies directed towards investigating or developing process improvements, such as optimizing your candidates’ crystallinity and purity profile.
Solid state reactions are generally much slower and more difficult to interpret than solution state reactions, therefore implementing stress conditions is a critical step in the investigation of stability. Data obtained under multiple given stress conditions are then extrapolated to make a prediction of stability under appropriate storage conditions.
