Rifampicin, a potent inducer of CYP3A4, but also CYP2C8, acts both as an inducer and inhibitor of
the metabolism of repaglinide. Seven days pre-treatment with rifampicin (600 mg), followed by co-
administration of repaglinide (a single dose of 4 mg) at day seven resulted in a 50% lower AUC
(effect of a combined induction and inhibition). When repaglinide was given 24 hours after the last
rifampicin dose, an 80% reduction of the repaglinide AUC was observed (effect of induction alone).
Concomitant use of rifampicin and repaglinide might therefore induce a need for repaglinide dose
adjustment which should be based on carefully monitored blood glucose concentrations at both
initiation of rifampicin treatment (acute inhibition), following dosing (mixed inhibition and
induction), withdrawal (induction alone) and up to approximately two weeks after withdrawal of
rifampicin where the inductive effect of rifampicin is no longer present. It cannot be excluded that
other inducers, e.g. phenytoin, carbamazepine, phenobarbital, St John’s wort, may have a similar
effect.
