Interactions between your drugs
nizatidine nelfinavir
Applies to: Axid Oral Solution (nizatidine), nelfinavir
There is currently no information in the medical literature regarding a potential interaction between nelfinavir and H2-receptor antagonists. Nelfinavir peak plasma concentration (Cmax), systemic exposure (AUC) and trough plasma concentration (Cmin) decreased by 37%, 36% and 39%, respectively, when nelfinavir (1250 mg twice daily) was coadministered with omeprazole (40 mg once daily 30 minutes before nelfinavir) for 4 days, presumably due to decreased solubility of nelfinavir as gastric pH increased. Although theoretically possible, it is not certain to what extent such an interaction may occur with H2-receptor antagonists, or whether it is clinically relevant. Caution may be advisable during coadministration.
