DRUG INTERACTION
Zepdon combined with atazanavir causes increasing the concentration of Raltegravir. Raltegravir is not inhibits the CYP1A2, 2B6, 2C8, 2C9, 2C19, 2D6 or 3A. Raltegravir not prohibits the P-gp mediated transport. Zepdon tablets are combined with rifampin causes depletion of plasma concentration of Raltegravir.
In case of this combination, the dose of Zepdon should be increased for reducing this adverse. Zepdon interaction with atazanavir/ritonavir, causes increasing concentration of Raltegravir Zepdon tablets are concurrently used with efavirenz leads to cause decreasing the concentration of Raltegravir.
Zepdon with efavirine causes decreasing concentration of Raltegravir Zepdon tablets combined with tipranavir/ritonavir, causes depleting the effect of concentration of Raltegravir. Co administration of Zepdon with gastric regulators should be avoided, because this combination leads to increase the effect of concentration of Raltegravir.
