| Abstract: | A simple,sensitive and rapid RP-HPLC method for the simultaneous deter mination of concentation of Phenobarbital (PBT),Phenytoin(PHT)and Carbamazepine(CBZ) in hUman serum is established. Using acetophenoen as internal standard and chloroform to extract drugs in plasma. The mobile phase consists of methanol - water (55/45, v/v). and flow rate is 1. 0ml/min, UV detecor 220nm. The recoveries of PBT, PHT and CBZ is 99.39%, 98. 35%and 99- 69% respectively. Within -runCV and between - run CV is less than 5%,the method has a good linearity. The assay has been used to determine the drug level in plasma in eight patients. |
