ABSTRACT

This work deals with the simultaneous estimation of famotidine and diclofenac potassium in a tablet dosage form. The method employed is simultaneous equation. The absorption maxima at 266 nm and 286 nm were used for the estimation of famotidine and diclofenac, respectively. Both the drugs and their mixture obey Beer-Lamberts law at selected wavelength in given concentration range. The result of analysis has been validated statistically and recovery studies confirmed the accuracy of the proposed method. The proposed method is simple, rapid, precise and accurate. It is used for the routine analysis of both drugs.
