Molecular interaction between drug-excipient and its implication on the formulation design of poorly water soluble drugs

With the extensive implementation of combinatorial chemistry and high throughput screening by the pharmaceutical industry, a large percentage (>50%) of identified drug development candidates are poorly water-soluble, which presents a critical hurdle for the pre-clinical and clinical assessments, as well as commercial drug product development.In many conventional solid dosage forms, drug molecules often exists as crystalline particles in the formulation thus drug-excipient interactions are often neglect-able, and the dissolution seldom generate solution supersaturation.While in many alternative formulations for solubilize enhancement, such as drug-polymer solid dispersions, solubilized capsules, etc.,drug disperses within the excipients as amorphous, molecular forms, and solution supersaturation is often observed once these formulations meet aqueous medium.
