Possible Interaction: Garlic and Darunavir

supplement:

Garlic

Research Papers that Mention the Interaction

Aged garlic extract significantly inhibited saquinavir efflux from rat hepatocytes, while the efflux of darunavir significantly increased.
All tested phytochemicals (except S-allyl L-cysteine) and aged garlic extract inhibited CYP3A4 metabolism of both drugs and modulated hepatic distribution of the corresponding saquinavir and darunavir metabolites.

Invitro studies reported that garlic extracts increased DRV Pglycoprotein-mediated efflux leading to a decrease in intracellular concentration of DRV in both enterocytes and hepatocytes [4, 5].
We report two cases of HIV-infected patients displaying clinically significant interactions between garlic and darunavir (DRV), which resulted in sub-therapeutic DRV plasma concentration associated with viral rebound.

Because of the observed in vitro interactions between aged garlic extract and HIV protease inhibitors ( darunavir , saquinavir), any alterations of in vivo liver transport in the presence of garlic phytochemicals could also significantly influence darunavir/saquinavir hepatocyte intracellular concentrations and hence their bioavailabilities.
