摘要

The aqueous solubility of poorly water-soluble drugs is an important factor of manyfactors affecting their bioavailability such as the solubility and rate of dissolution inwater. A series of attempts to enhance the bioavailability of poorly water-soluble drugshave been made by the fine grinding technique using a planetary ball mill. For theprediction of aqueous solubility, the experimental solubility data was collected andextracted by Tanimoto similarity filter then the QSPR approach using genetic algorithm(GA) was applied. The possibility of improving the bioavailability properties of thedrugs such as ursodeoxycholic acid (UDCA), diphenyl hydrantoin (phenytoin) andbiphenyl dimethyl dicarboxylate (DDB) based on the molecular interaction betweendrug and additives occurred by mechanochemical effect during ultra-fine grindingprocess has been discussed in comparison with experimental data and predicted data ofintrinsic bioavailability of the drugs based on molecular modeling approach and in vitrotest for the drugs.
