| Abstract:
|
Simple and sensitive extractive spectrophotometric methods for the determination of Imatinib in pure form and in
pharmaceutical formulations using triphenyl methane dyes have been developed. The developed methods involved formation
of coloured chloroform extractable ion-pair complexes of Imatinib with triphenyl methane dyes viz., bromothymol blue,
bromophenol blue, bromocresol green and bromocresol purple in acidic medium. The extracted complexes formed with
the above dyes showed absorbance maxima at 415, 416, 412 and 407 nm respectively, The stoichiometry of the ion-pair
complexes of Imatinib with dyes is found to be 1:1 in each case and Beer’s law is obeyed in the concentration range 2.5-
25µg/ml of drug with dyes. The effect of concentration of dye, pH, and interference of excipients has been studied for
optimization. The limits of detection and quantification have been determined for all the four methods. These methods have
been validated as per the guidelines of ICH. The results of analysis were validated statistically through recovery studies.
