Guanfacine and Inrebic
Determining the interaction of Guanfacine and Inrebic 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:Consumer information for this interaction is not currently available.MONITOR: Coadministration with inhibitors of CYP450 3A4 may increase the plasma concentrations of guanfacine, which is primarily metabolized by the isoenzyme. Ketoconazole, a potent CYP450 3A4 inhibitor, has been reported to increase guanfacine peak plasma concentration (Cmax) and systemic exposure (AUC) by approximately 2- and 3-fold, respectively. A computer simulation suggests that fluconazole, a moderate CYP450 3A4 inhibitor, would increase guanfacine Cmax and AUC by about 1.5- and 2-fold, respectively. MANAGEMENT: Caution is advised when guanfacine is used with CYP450 3A4 inhibitors. Patients should be monitored for increased adverse effects such as hypotension, bradycardia and sedation , and the guanfacine dosage adjusted as necessary. References "Product Information.
