CO-DETERMINATION OF TWO ANTIPARASITICS DRUGS BY DERIVATIVE SPECTROPHOTOMETRY AND ITS PHOTODEGRADATION STUDIES

CO-DETERMINATION OF TWO ANTIPARASITICS DRUGS BY DERIVATIVE SPECTROPHOTOMETRY AND ITS PHOTODEGRADATION STUDIES

This work proposes a method for the co-determination of praziquantel and fenbendazole in veterinary pharmaceutical formulations (VPF) by second-derivative spectrophotometry at 226.4 nm (Zero-crossing method) and 324.6 nm (Graphic method), respectively. The excipients commonly used in VPF do not inte...
