Advantages of simultaneous stability studies are the identification of new degradation products, to understand mutual induction and/or inhibition of rates of degradation and to analyze the degradation products of both drugs. Various ultraviolet spectroscopic and high performance liquid chromatographic assay methods were reported for the estimation of metformin, sitagliptin, pioglitazone, glimepiride and simvastatin individually and in combination with other drugs. All the above reported methods were based on the estimation of metformin, sitagliptin, pioglitazone, glimepiride and simvastatin alone or in combination with other drugs. The degradation products were generated and successfully separated by the developed and validated high performance liquid chromatographic methods for the estimation of the selected anti-diabetic drug combinations. The aim of the study was to develop and validate of Q-Absorbance Ratio UV-Spectrophotometric Method for Simultaneous Estimation of Metformin and Empagliflozin in Bulk and Combined Dosage Form.

A simple, accurate, precise high-performance liquid chromatographic (HPLC) method has been developed and validated for the simultaneous determination of abacavir sulphate (ABA) and lamivudine (LAM) in combined dosage form. Separation was performed on a C18 column [Agilent ODS UG 5 column, 250 mm x 4.5 mm], with methanol: water (50:50 V/V) isocratic elution using a flow rate of 1mL/min. Good sensitivity was observed with UV detection at 277 nm. After method development, the interference of other active compounds and excipients, repeatability and linearity, were investigated. Retention times of LAM and ABA were found to be 3.3 and 6.3 min, respectively. The method was validated over the range from 2.5-12.5 μg/mL for LAM and 5-25 μg/mL for ABA with correlation coefficients of 0.9997 and 0.9996, respectively. This method was shown to be accurate, robust, selective, linear, and repeatable and can be successfully employed in routine quality control for the simultaneous analysis of ABA and LAM in tablets.
