Separation of five antipyretic analgesics by micellar electrokinetic capillary chromatography.
The derivatives of antipyrine and phenylbutazone are important antipyretic analgesics commonly used in clinical medicine. Although high performance liquid chromatography has been the conventional method used for the analysis of these drugs, in recent years capillary electrophoresis was validated to be a useful method in the analysis of antipyretic analgesics. However, there has been no report on the separation of antipyrine (AP), 4-aminoantipyrine (4-AAP), aminopyrine (APY), dipyrone (DIP) and phenylbutazone (PHE) in the literature. In this paper, a micellar electrokinetic capillary chromatographic (MECC) separation method was described for the five antipyretic analgesics.
