Table 6: Summary of drug-drug interactions of BANZEL with other antiepileptic drugs AED Co-administered Influence of Rufinamide on AED concentration a) Influence of AED on Rufinamide concentration Carbamazepine Decrease by 7 to 13% b) Decrease by 19 to 26% Dependent on dose of carbamazepine Lamotrigine Decrease by 7 to 13% b) No Effect Phenobarbital Increase…

Effects of Other AEDs on BANZEL Potent cytochrome P450 enzyme inducers, such as carbamazepine, phenytoin, primidone, and phenobarbital, appear to increase the clearance of BANZEL (see Table 6).

If abrupt discontinuation of the drug is medically necessary, the transition to another AED should be made under close medical supervision.

Effects of BANZEL on other AEDs Population pharmacokinetic analysis of average concentration at steady state of carbamazepine, lamotrigine, phenobarbital, phenytoin, topiramate, and valproate showed that typical rufinamide C avss levels had little effect on the pharmacokinetics of other AEDs.

Table 6 summarizes the drug-drug interactions of BANZEL with other AEDs.

Effects of other Antiepilepsy Drugs (AEDs) on Tiagabine HCl: Carbamazepine : Population pharmacokinetic analyses indicate that tiagabine clearance is 60% greater in patients taking carbamazepine with or without other enzyme-inducing AEDs.

Phenytoin : Population pharmacokinetic analyses indicate that tiagabine clearance is 60% greater in patients taking phenytoin with or without other enzyme-inducing AEDs.

Phenobarbital (Primidone) : Population pharmacokinetic analyses indicate that tiagabine clearance is 60% greater in patients taking phenobarbital (primidone) with or without other enzyme-inducing AEDs.

Effects of Tiagabine HCl on other Antiepilepsy Drugs (AEDs): Phenytoin : Tiagabine had no effect on the steady-state plasma concentrations of phenytoin in patients with epilepsy.
