Overlap spectra of tartrazine and CPM at an analytical wavelength and peak tailing were the main problem occurs in CPM tablets analysis. The aim of this study was to develop a derivative UV spectrophotometry and a modified HPLC to overcome the problem in CPM tablet analysis. Both validated methods were applied for the determination of CPM content in three registered CPM tablets. As a result, the first derivative spectrophotometry method obtained the δA/δλ of tartrazine in matrix tablet was nearly zero at the wavelength of 232 nm and did not interfere with the δA/δλ of CPM. The selective mobile phase for separation of CPM from tartrazine using HPLC method was a mixture of phosphate buffer pH 4 and methanol (60:40 v/v) with a flow rate of 1 ml/min. The CPM separated from tartrazine and other peaks in sample(s) with Rs of >1.5 The linearity, accuracy, and precision of these two methods fulfilled the reference requirement. No significant difference observed between the CPM content in artificial tablets when analyzed using first-derivative spectrophotometry and HPLC method. The concentration of CPM in one registered tablet that had been assayed using spectrophotometry, HPLC and the standard method was not significantly different. As a conclusion first-derivative spectrophotometry and HPLC method were valid for the determination of CPM in a tablet containing tartrazine. However, the first-derivative spectrophotometry method was more efficient than HPLC. Keywords : Chlorpheniramine maleate; tartrazine; UV-spectrophotometry; HPLC; method validation
