The present work aims to establish a simple, precise and rapid spectrophotometric method for quantifying telmisartan in active pharmaceutical ingredients. This work was carried out to estimate telmisartan in bulk by utilizing an area under curve (AUC) method using uv-visible spectrophotometry. For this purpose, the wavelength range between 200-400 nm was selected. Ethanol was used as a solvent throughout the work. Linearity was obtained in the concentration range of 2 to 10 g/ml (r2 =0.998) for the method. The developed method was found to be simple, highly sensitive and can be used for routine quality control analysis for spectrophotometric estimation of active pharmaceutical ingredients.
