Symproic and Telotristat Etiprate

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 information for this interaction is not currently available.MONITOR: Coadministration with telotristat ethyl may decrease the plasma concentrations of drugs that are substrates of CYP450 3A4 and/or 2B6 isoenzymes. The proposed mechanism is accelerated clearance due to induction of CYP450 3A4 and/or 2B6 (in vitro) isoenzymes by telotristat ethyl. When the probe CYP450 3A4 substrate midazolam (3 mg) was administered orally after 5 days of treatment with telotristat ethyl 500 mg three times daily (twice the recommended dosage), mean midazolam peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 25% and 48%, respectively, compared to administration of midazolam alone. The mean Cmax and AUC of the active metabolite, 1'-hydroxymidazolam, also decreased by 34% and 48%, respectively. This suggests induction by telotristat ethyl of the glucuronidation of 1'-hydroxymidazolam. MANAGEMENT: When drugs that are known substrates of CYP450 3A4 and/or 2B6 are coadministered with telotristat ethyl, the possibility of a diminished therapeutic response to those drugs should be considered. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs, particularly those with a narrow therapeutic range, whenever telotristat ethyl is added to or withdrawn from therapy.
