Abstract

This research aimed to develop inexpensive, safe, rapid, efficent spectrophotometric method for the assay of atenolol in some antihypertensive drugs namely Normoten in its pharmaceutical formulation. The studied method is depend on the reaction of the drug with phenol red in acidic medium, at pH 3.0. The analytical parameters have been investigated. The maximum absorbance was obtained at 429 nm and the molar absorptivity of 0.054 L mol-1 cm-1. Beer’s law is linear in the concentration range of 0.5-100 μg/mL for atenolol in Normoten. The detection and quantification limits were found to be 0.038 and 0.113μg/mL for the atenolol in Normoten respectively, and with a linear regression correlation coefficient of 0.997. The recovery was found to be 98.94 to 100.31%. The studied method is can be applied for the determination of atenolol (active ingredient) of the antihypertensive drugs in their pharmaceutical formulations.
