Sensitive high-performance liquid chromatographic determination of arbidol, a new antiviral compound, in human plasma.
A highly sensitive and selective HPLC method was developed and validated for the determination of arbidol in human plasma. The method involves the liquid-liquid extraction of drug and internal standard from plasma with tert.-butyl methyl ether followed by evaporation and reconstitution in mobile phase. UV detection was done at 315 nm. The limit of quantification for arbidol in plasma was 0.005 microgram/ml. Linearity in plasma was proven over the whole calibration range (10.2-0.005 micrograms/ml). The method was validated according to GLP guidelines and its suitability was demonstrated by analysis of samples from a pharmacokinetic study.
