Hi everybody,Back to the Top
I'm searching for an inhibitor of CYPs in rats, that I can use in vivo,
and which not interfere with efflux proteins, specially P-gp (neither
substrate, inhibitor nor inducer) .
Thank You in advance ! Will certainly appreciate any response.

Due to substrate specificity overlap it might be difficult, cyclosporine isBack to the Top
definitely out as it is a know inhibitor of PGP as well, maybe itraconazole
or ketoconazole but I am less knowledgable of their PGP profile. One
should consider grapefruit juice if inhibition of 3A4 and 3A5 can be
limited to intestinal metabolism, some suggest that it might induce PGP but
it is less clear, see Kane et al, Mayo Clin Proc 2000;75:933-942.
