A simple, sensitive and specific HPLC method with UV detection (210 nm) was developed and validated for quantitation of Valdecoxib in human plasma, the newest addition to the group of non-steroidal anti-inflammatory drugs-a highly selective cyclooxygenase-2 inhibitor. The analyte and an internal standard (Rofecoxib) were extracted with diethyl ether/dichloromethane (70/30 (v/v)). The chromatographic separation was performed on reverse phase ODS-AQ column with an isocratic mobile phase of water/methanol (47/53 (v/v)). The lower limit of quantitation was 10 ng/ml, with a relative standard deviation of <20%. A linear range of 10-500 ng/ml was established. This HPLC method was validated with between-batch and within-batch precision of 1.27-7.45 and 0.79-6.12%, respectively. The between-batch and within-batch bias was 0.74-7.40 and -0.93 to 7.70%, respectively. Frequently coadministered drugs did not interfere with the described methodology. Stability of Valdecoxib in plasma was excellent, with no evidence of degradation during sample processing (autosampler) and 30 days storage in a freezer. This validated method is suitable for bioequivalence studies following single dose in healthy volunteers.
