Abstract
A method for increasing the water-solubility of highly insoluble organic compounds by forming a complex product from the reaction between the organic compound and an aqueous solution of solid polyvinylpyrrolidone. The solubility of the organic compound can be increased at least 25-fold and the complex formed is highly stable at ambient conditions.
