Since drug molecules usually have different solid forms, including salts, polycrystals, eutectic, amorphous, hydrates and solvent compounds; moreover, different crystal forms of the same drug molecule may have significant differences in properties such as crystal structure, stability, producibility and bioavailability, which directly affect the efficacy and exploitability of the drug. If the best crystalline form is not well evaluated and selected for development, crystalline changes may occur in the late clinical stage, resulting in significant financial losses due to delayed marketing, and even more significant losses if the drug is withdrawn from the market due to crystalline changes after marketing. CD Formulation provides professional testing services for drug crystalline forms and solid-state development.
