Aim of this research was development and implementation of a simple, precise and accurate zero order spectroscopic method for the estimation of levetiracetam in bulk and tablet dosage form. The drug indicates the maximum absorption (λmax) at 206 nm in 0.5 N HCl solutions (pH about 3.3) and AUC in the absorption spectrum is measured in the wavelength range from 204 to 208 nm at a concentration range of 5-30 µg/ml according to Beer’s law. Linearity analysis showed an R2 value of 0.998. The %Recovery was found to be 99.99 to 100.92 %. The LOD and LOQ were found to be 0.0110 and 0.33 µg/ml. The %RSD was found less than 2. The method has been validated according to linearity, precision, accuracy, robustness, ruggedness, LOD and LOQ according to ICH guidelines. This method obeys the Beer’s law and met all the required specifications within the limit. FTIR data interpretation also gives information about purity and quality of sample and it also meets the required specifications....
Teneligliptin and metformin are FDA-approved medications recently introduced for managing type 2 diabetes. This study aims to develop UV spectrophotometric methods for the simultaneous quantification of teneligliptin and metformin in pharmaceutical formulations, alongside conducting forced degradation studies under four distinct stress conditions. The methods utilize Vierordt's Method with distilled water as the solvent. The absorption maxima for metformin and teneligliptin were identified at 230.4 nm and 245 nm, respectively, with no interference between the two. Stability assessments were carried out under acidic, alkaline, oxidative (peroxide) and thermal stress. The forced degradation studies highlighted the robustness of the developed method under various stress conditions. The method adhered to Beer’s law within the concentration ranges of 2-14 μg/ml for metformin and 10-40 μg/ml for teneligliptin. Statistical validation confirmed the method’s reliability. This approach proved to be rapid, precise and cost-effective for routine analysis of pharmaceutical formulations. Insights from the degradation studies may guide the formulation of more stable products and inform the proper storage practice....
