Highly concentrated aqueous solutions of various hydrotropic agents like sodium benzoate, sodium salicylate, sodium acetate, sodium citrate, nicotinamide and sodium ascorbate have been observed to enhance aqueous solubilities of a large number of poorly water-soluble drugs. In the present investigation hydrotropic solubilization technique has been employed to solubilize poorly water-soluble aspirin (analgesic and antipyretic drug) by 0.5 M ibuprofen sodium solution to carry out titrimetric analysis of aspirin in tablet dosage form. Results of analysis by proposed method and Phamacopoeial method are very comparable. Proposed method is new, rapid, simple, accurate, and reproducible. Statistical data proved the accuracy, reproducibility and the precision of proposed method.
