Abstract
The quantitative analysis of different brands of Diclofenac tablets was carried out (using HPLC and U.V spectrophotometric method) to determine if the drugs are of required standards. The results obtained from analysis of the various drugs were compared with that of the standard. The percentage content for each sample was calculated using the absorbance and peak areas of the samples and that of the standard to see if they are within the specified limit as stated by the official books. Diclofenac has a range of 95.0%-105% as stated by B. P 2008, UV result shows that 5 samples of the drug passed and 5 failed while for HPLC, only 1 sample passed.
