Résumé
Rifampicin can lower mycophenolic acid exposure, which may reduce immunosuppression and raise the risk of rejection or graft-versus-host disease. The effect has been seen in transplant recipients and may emerge within days of starting rifampicin.
Ce que signifie cette interaction, en termes simples
