A simple, sensitive indirect visible spectrophotometric method has been developed for the estimation of almotriptan malate either in bulk or tablet dosage forms. The method is based on the oxidation of drug with excess N-Bromo succinimide and determining the unreacted NBS with reagents PMAP-SA by spectrophotometrically at 520nm Beer's law obeyed in the concentration range of 4–20 μg/ml. No interference was observed from the usually existing additives in pharmaceutical formulations and the applicability of the method was examined by analyzing AXERT tablets containing AM. The statistical data indicates the accuracy, reproducibility and the precision of the proposed method.
