    Poorly Soluble APIs: How Surface Contact Shapes Dissolution and Bioavailability

    Poorly soluble APIs now represent the majority of the pharmaceutical development pipeline. Dissolution and oral bioavailability are determined by molecular solubility, surface wetting behavior, solid-state stability, and how the formulation interacts with the GI environment from first contact onward. Amorphous dispersions, lipid systems, nanocrystals, and co-crystals each rely on different surface mechanisms to deliver their intended advantage.
