“As compared to the cimetidine group, pre‐treatment using either GSH or NAC with Cimetidine produced a marked decrease in lidocaine levels (37 ± 27 and 63 ± 28 ng/mL, respectively) and no modification of MEGX levels (155 ± 12 and 165 ± 22 ng/mL, respectively).”
“These results suggest that GSH and NAC might accelerate the lidocaine metabolism while counteracting the inhibitory effect of Cimetidine.”
