Abstract
A rapid spectrophotometric method for the analysis of chlorphenoxamine hydrochloride in combination with unhydrous caffeine was described. The method is based on the determination of chlorphenoxamine hydrochloride by at 225 and 232 nm while unhydrous caffeine recorde zero at the same wave lengths. Unhydrous caffeine determined by at 256 and 283 nm which corresponding to zero reading for chlorphenoxamine hydrochloride.Keywords
