ABSTRACT
A simple, precise, reliable, specific and accurate Reverse phase high
performance liquid chromatography method was developed for
estimation of Famotidine in bulk and in it’s tablet dosage form was
carried out on a BDS C8 (4.6×250mm) 5μ column using a mixture of
Methanol: buffer pH3 (80:20) as the mobile phase at a flow rate of
1.0ml/min, the detection was carried out at 288nm. The retention time
of the Famotidine was 3.7min. The method produced linear responses
in the concentration range of 20-100μg/ml of Famotidine. The
correlation coefficient of Famotidine was found to be 0.996. The
method precision for the determination of assay was below 2.0% RSD.
The LOD values for Famotidine were found 1.303μg/mL. The LOQ
values for Famotidine were found 3.95μg/mL. The method can be used
for the quality analysis of bulk and pharmaceutical formulations.
Keywords: Famotidine, RP-HPLC, validation, BDS, LOD, LOQ, %RSD.
