The present manuscript describes simple, sensitive, rapid, accurate, precise and economical First order derivative spectrophotometry method for the simultaneous determination of Meropenem and Sulbactam Sodium in bulk and combined dosage form. The absorbance values at 333nm and 252 nm of first derivative spectrum was used for the estimation of Meropenem and Sulbactam Sodium, respectively without mutual interference. This method obeyed beer’s law in the concentration range of 5-70 μg/ml for Meropenem and 2-21 μg/ml for Meropenem. The method was successfully applied to pharmaceutical combined dosage form because no interference from the excipients was found. The suitability of this method for the quantitative determination of Meropenem and Sulbactam Sodiumwas proved by validation. The proposed method was found to be simple and sensitive for the routine quality control analysis of Meropenem and Sulbactam Sodium in bulk and combined dosage form. The results of analysis have been validated statistically and by recovery studies.
