In the present investigation 0.5 M ibuprofen sodium solution has been used as hydrotropic solubilizing agent for naproxen, a poorly water-soluble drug and in it there was more than 350 fold enhancement in the solubility of naproxen as compared to the solubility in distilled water. Therefore, this hydrotropic solution was employed to extract out the drug from its tablet dosage form for quantitative estimation by titrimetry. The naproxen has been successfully analyzed in tablets. The results of analysis obtained by proposed method compared well with those by corresponding British pharmacopoeial method involving the use of methanol. The proposed method was also validated by recovery studies. Presence of ibuprofen sodium and common excipients did not interfere in analysis. Proposed method is new, simple, economic, safe, rapid, accurate, reproducible and environment-friendly.
