dc.description.abstractBidirectional transport studies were conducted using Caco-2, MDCK, and MDCK–MDR1 to determine P-gp influences in lamivudine and zidovudine permeability and evaluate if zidovudine permeability changes with the increase of zidovudine concentration and/or by association of lamivudine. Transport of lamivudine and zidovudine separated and coadministrated across monolayers based on these cells were quantified using LC–MS–MS. Drug efflux by P-gp was inhibited using GG918. Bidirectional transport of lamivudine and zidovudine was performed across MDCK–MDR1 and Caco-2 cells. Statistically significant transport decrease in B!A direction was observed using MDCK–MDR1 for zidovudine and MDCK–MDR1 and Caco-2 for lamivudine. Results show increased transport in B!A and A!B directions as concentration increases but data from Papp increase in both directions for both drugs in Caco-2, decrease in MDCK, and does not change significantly in MDCK–MDR1. Zidovudine transport in A!B direction increases when coadministrated with increasing lamivudine concentration but does not change significantly in B!A direction. Zidovudine and lamivudine are P-gp substrates, but results assume that P-gp does not affect significantly lamivudine and zidovudine. Their transport in monolayers based on Caco-2 cells increase proportionally to concentration (in both directions) and zidovudine transport in Caco-2 cell monolayer does not show significant changes with lamivudine increasing concentrations.pt_BR
