RESUMEN
An improved and simplified high-performance liquid chromatographic (HPLC) method at UV detection 265 nm is presented for the determination of d4T in rat plasma. The mobile phase consists of methanol-distilled water-acetic acid in the 23:77:0.2 (v/v) ratio. Quantification is achieved by the peak-area ratio method with reference to the internal standard. This paper presents linearity, accuracy, precision, limit of quantification and limit of detection, specificity-selectivity and sample stability data. Based on the intra and inter-day validation, all coefficients of variation (CV) were found less than 15%. The assay is sufficiently rapid and sensitive and was applied in a pharmacokinetic study in rats.
