Surface Characterization as a Tool for Identifying the Factors Affecting the Dissolution Rate of Amorphous Solid Dispersion Tablets.

An amorphous solid dispersion (ASD) is a commonly used approach to enhancing the dissolution of poorly aqueous soluble drugs. Selecting the desired polymer and drug loading can be time-consuming. Surface properties, such as surface composition and wetting behavior, are essential factors controlling the dissolution of ASD tablets.
