Abstract:
A rapid method for the determination of chlorpheniramine maleate in tablets using second-derivative absorption spectrophotometry is described. The method has the advantage of requiring simple sample preparation and having accuracy comparable to the official acid-alkaline solvent extraction procedure. Results of recovery tests were close to 100%.
