Eslicarbazepine (Aptiom) and Ketamine Therapy | Tovani Health
Aptiom (Eslicarbazepine) — Sodium channel blocker AED (focal seizures)
Verdict at Tovani Health
Modest CYP3A4 induction — lighter than carbamazepine, similar to oxcarbazepine; may slightly lower ketamine levels.
Eslicarbazepine and ketamine are compatible with planning. Eslicarbazepine is the third-generation member of the carbamazepine/oxcarbazepine sodium channel blocker family, with cleaner kinetics than carbamazepine and a milder side effect profile. The CYP3A4 induction is modest — lighter than carbamazepine but real — which can slightly accelerate ketamine metabolism and modestly lower plasma levels. We may adjust KAP dose upward if you're on chronic eslicarbazepine; not as dramatic a change as with phenytoin or rifampin. Hyponatremia (like oxcarbazepine) is the intrinsic consideration to monitor independent of KAP.
If you take Aptiom regularly and are considering at-home ketamine therapy, the combination is safe with monitoring or modest dose adjustment. This page covers the brief pharmacologic context and what we do at intake.
How Aptiom interacts with ketamine
Eslicarbazepine is the prodrug of S-licarbazepine, which blocks voltage-gated sodium channels. Modest CYP3A4 inducer; UGT inducer. Renally cleared. The active metabolite is the same as oxcarbazepine's active metabolite — basically same chemistry, cleaner formulation.
What we do at intake
Continue your AED regimen. We may adjust KAP dose upward to account for modest accelerated metabolism. Watch sodium levels (intrinsic).
