  Article history:

  Ketoprofen or [2-(3-benzoylphenyl)propionic acid] is a nonsteroidal antiinflammatory and analgesic agent.

AutoDock was used for docking. Parameters observed were crystal; co-former; type and energy (Ei) of interaction. The work was continued by co-crystallization process and solubility assay of ketoprofen; molecular the mixtures according to Higuchi and Connor method using UV spectrophotometer. Based on molecular docking; saccharin. docking, the best co-former is saccharin (Ei = -3.14 kcal/mol). The docking result fits the solubility assay of the ketoprofen-saccharin co- crystal (300.62 μg/mL in water or 256.54% increasing of solubility compared to ketoprofen). Ketoprofen co-crystal shows better curve (90.15 % in 60 minutes) than ketoprofen (78.87 % in 60 minutes). Co-crystallization of ketoprofen with saccharin increases the dissolution profile of ketoprofen. been widely used to enhance the solubility of poorly water soluble
