Donnatal (Hyoscyamine, Atropine, Scopolamine, and Phenobarbital Elixir) and Varubi Intravenous
Determining the interaction of Donnatal (Hyoscyamine, Atropine, Scopolamine, and Phenobarbital Elixir) and Varubi Intravenous and the possibility of their joint administration.
In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.
Consumer:PHENobarbital may significantly reduce the blood levels of rolapitant, which may make the medication ineffective or less effective in treating your condition. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:GENERALLY AVOID: Coadministration with potent inducers of CYP450 3A4 may significantly decrease the plasma concentrations of rolapitant, which is primarily metabolized by the isoenzyme. When the potent CYP450 3A4 inducer rifampin was administered at 600 mg once daily for 7 days before and 7 days after a single 180 mg dose of rolapitant, mean rolapitant peak plasma concentration (Cmax) and systemic exposure decreased by 30% and 85%, respectively, compared to administration of rolapitant alone. Mean half-life of rolapitant decreased from 176 hours to 41 hours with rifampin. Loss of therapeutic efficacy may occur.
MANAGEMENT: Rolapitant should not be used in patients who require chronic treatment with potent CYP450 3A4 inducers.
