Validation of a simple HPLC method for DRF-4848, a novel COX-2 inhibitor suitable for pharmacokinetic application in rats.

For pharmacokinetic and toxicokinetic purpose a simple HPLC-UV method has been developed and validated for the estimation of DRF-4848, a novel COX-2 inhibitor in rat plasma. A liquid-liquid extraction was used to extract DRF-4848 and internal standard (IS, DRF-4367) from rat plasma. The analysis was performed on a C(18) column with UV detection at 285 nm… CONTINUE READING
