Kliniske data fra raske frivillige understøtter, at CYP2C8 er det vigtigste enzym, som er involveret i repaglinid metabolismen med CYP3A4 i en underordnet rolle, men den relative virkning af CYP3A4 kan øges, hvis CYP2C8 hæmmes.
Clinical data in healthy volunteers support CYP2C8 as being the most important enzyme involved in repaglinide metabolism with CYP3A4 playing a minor role, but the relative contribution of CYP3A4 can be increased if CYP2C8 is inhibited.
