Abstract

COCRYSTALLIZATION OF KETOPROFEN AND BENZOIC ACID BY USING SOLVENT- DROP GRINDING METHOD

Jayashree Gaja*, K. Jesindha Beyatricks and S. Tharani

ABSTRACT

The purpose of this work was to prepare ketoprofen-benzoic acid cocrystal by solvent drop grinding method to improve solubility of the drug Ketoprofen. Ketoprofen and conformer benzoic acid in molar ratio 1:1 was used to formulate molecular complex using methanol as solvent. Characterization of cocrystal was done by Differential Scanning Calorimetry (DSC), Fourier Transform Infrared (FTIR) Spectroscopy. The formed cocrystal of Ketoprofen exhibits different physicochemical characteristics compared to the constituent materials. The prepared cocrystal showed an improvement in solubility with respect to the pure drug.

Keywords: Co-crystals, Co-formers, Solvent drop technique, Ketoprofen, Solubility.
