Pharmacokinetic interaction between RSV and alcohol. (A) Pharmacokinetic study design of RSV, alcohol and their combination in mice; (B) Typical multiple–reaction monitoring chromatograms of blank mouse blood(a), a blank mouse blood sample spiked with alcohol and IS(b), and a blood sample after the intragastric administration of alcohol (c). (C) Pharmacokinetics of alcohol in the alone and combination groups. (D)Typical multiple-reaction monitoring chromatograms of blank mouse blood(a), a blank mouse blood sample spiked with RSV, R3G, R3S, and IS(b), and a blood sample after the intragastric administration of RSV(c). (E) Pharmacokinetics of RSV and its main metabolites in the alone and combination groups. * p < 0.05; *** p < 0.001.
