AN11 Evaluating Solid Dispersion using Small-Scale Dissolution Testing

In their efforts to enhance the bioavailability of poorly soluble drugs in BCS Class II, formulators often work with amorphous forms, which are many times more soluble than crystals of the same substance. The problem is, how can the amorphous drug be preserved, even though its natural tendency is to crystallise? One way is to prepare it as a solid dispersion.
