Posaconazolplasmakoncentrationer (Cmax og AUC) reduceredes med 39%, da posaconazol blev administreret samtidig med cimetidin (400 mg 2 gange dagligt) på grund af reduceret absorption, som muligvis var sekundær til reduktion af mavesyreproduktionen.
Posaconazole plasma concentrations (Cmax and AUC) were reduced by 39% when posaconazole was administered with cimetidine (400 mg twice a day) due to reduced absorption possibly secondary to a decrease in gastric acid production.
