“ Meloxicam , in turn, decreased both Km and Vmax of quinidine metabolism by CYP 3A4, indicating an uncompetitive inhibition mechanism.”
“ Quinidine and hydroquinidine decreased Km and increased Vmax of meloxicam hydroxylation, which was consistent with a mixed-type nonessential activation.”
“ Quinidine , a CYP 3A4 substrate commonly used as a selective in vitro inhibitor of CYP 2D6, was found to markedly increase the rate of meloxicam hydroxylation during in vitro experiments with human liver microsomes.”
