The values were compared with the official specifications. The obtained result for weight variation is 0.58+0.71 to 2.13+3.01% and disintegration time were between 2.30+0.17 and 5.19+0.14 minutes. Loss on drying of all batches were in between 2.0933.17 and 2.52+2.84% and potency or assay result were 98.08+0.52 to 100.25+0.19%. Moreover, the release rate of different brands of cephradine was satisfactory within 45 minutes where the mean dissolution rate is 93.96+0.13 %.
