Drug Interactions between Fycompa and telotristat
This report displays the potential drug interactions for the following 2 drugs:
- Fycompa (perampanel)
- telotristat
Interactions between your drugs
perampanel telotristat ethyl
Applies to: Fycompa (perampanel) and telotristat
GENERALLY AVOID: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations and pharmacologic effects of perampanel, which is primarily metabolized by the isoenzyme. The interaction has been reported with known CYP450 3A4 inducers such as carbamazepine, oxcarbazepine, and phenytoin.
MANAGEMENT: According to the manufacturer, concomitant use of perampanel with strong CYP450 3A4 inducers should be avoided.

Drug and food interactions
perampanel food
Applies to: Fycompa (perampanel)
GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

telotristat ethyl food
Applies to: telotristat
ADJUST DOSING INTERVAL: Food increases the systemic exposure to both telotristat ethyl and its active metabolite, telotristat. Following administration of a single 500 mg dose of telotristat ethyl (twice the recommended dose) with a high-fat meal, telotristat ethyl peak plasma concentration (Cmax) and systemic exposure (AUC) were 112% and 264% higher, respectively, compared to administration under fasted conditions. The Cmax and AUC values for telotristat were also increased by 47% and 33%, respectively. The in vitro inhibitory potency of telotristat towards tryptophan hydroxylase has been shown to be approximately 29 times higher than that of the parent drug.
MANAGEMENT: Telotristat ethyl should be administered with food.
