Eslicarbazepine acetate

Identification

Summary

Eslicarbazepine acetate is an anticonvulsant agent used as an adjunct to treat partial-onset seizures in patients with inadequate clinical response to conventional antiepileptic therapy.

Brand Names
Aptiom, Zebinix
Generic Name
Eslicarbazepine acetate
DrugBank Accession Number
DB09119
Background

Eslicarbazepine acetate (ESL) is an anticonvulsant medication approved for use in Europe, the United States and Canada as an adjunctive therapy for partial-onset seizures that are not adequately controlled with conventional therapy. Eslicarbazepine acetate is a prodrug that is rapidly converted to eslicarbazepine, the primary active metabolite in the body. Eslicarbazepine's mechanism of action is not well understood, but it is known that it does exert anticonvulsant activity by inhibiting repeated neuronal firing and stabilizing the inactivated state of voltage-gated sodium channels, thus preventing their return to the activated state during which seizure activity can occur.

Eslicarbazepine acetate is marketed as Aptiom in North America and Zebinix or Exalief in Europe. It is available in 200, 400, 600, or 800mg tablets that are taken once daily, with or without food. Eslicarbazepine acetate is associated with numerous side effects including dizziness, drowsiness, nausea, vomiting, diarrhea, headache, aphasia, lack of concentration, psychomotor retardation, speech disturbances, ataxia, depression and hyponatremia. It is recommended that patients taking eslicarbazepine acetate be monitored for suicidality.

Pharmacodynamics

Eslicarbazepine acetate is associated with a dose- and concentration-dependant increase in heart rate and prolongation of PR interval.

Mechanism of action

Eslicarbazepine acetate is converted to the active metabolite eslicarbazepine which carries out its anticonvulsant activity. The exact mechanism of action is unknown, but it is thought to involve the inhibition of voltage-gated sodium channels. In in vitro electrophysiological studies, eslicarbazepine was shown to inhibit repeated neuronal firing by stabilizing the inactivated state of voltage-gated sodium channels and preventing their return to the activated state. In vitro studies also showed eslicarbazepine inhibiting T-type calcium channels, which likely also has a role in anticonvulsant activity.

Absorption

Eslicarbazepine active metabolite has a high bioavailability and reaches peak serum concentration 1-4 hours after a given dose. Eslicarbazepine acetate absorption is not affected by food.

Volume of distribution

The apparent volume of distribution of eslicarbazepine is 61.3 L for a body weight of 70 kg based on population PK analysis.

Protein binding

Eslicarbazepine is bound to plasma proteins at a relatively low rate of <40%, independent of concentration. In vitro studies have shown that plasma protein binding is not relevantly affected by the presence of other medications such as warfarin, diazepam, digoxin, phenytoin or tolbutamide. Similarly, the binding of these medications was not significantly affected by the presence of eslicarbazepine.

Metabolism

Eslicarbazepine acetate is rapidly and extensively metabolized to its major active metabolite, eslicarbazepine, via hydrolytic first-pass metabolism. Eslicarbazepine corresponds to about 92% of systemic exposure. Minor active metabolites (R)-licarbazepine and oxcarbazepine consist of <5% of systemic exposure. Active metabolites are then metabolized to inactive glucuronides that correspond to about 3% of systemic exposure.

Eslicarbazepine had a moderate inhibitory effect on CYP2C19 and a mild activation of UGT1A1-mediated glucuronidation when studied in human hepatic microsomes. It has been shown to induce CYP3A4 enzymes in vivo.

Route of elimination

Eslicarbazepine acetate and its metabolites are eliminated primarily via renal excretion. Eslicarbazepine active metabolite is excreted two-thirds in the unchanged form and one-third as a glucuronide conjugate. This accounts for around 90% of total metabolites excreted, with the remaining 10% being minor metabolites. Renal tubular reabsorption is expected to occur with eslicarbazepine.

Half-life

The apparent plasma half-life of eslicarbazepine is 10-20 hours in healthy subjects and 13-20 hours in epilepsy patients. Steady-state plasma concentrations are attained after 4 to 5 days of once daily dosing.

Clearance

Renal clearance of eslicarbazepine was found to be approximately 20 mL/min in healthy subjects with normal renal function.

Toxicity

There are no adequate and well-controlled studies of the use of eslicarbazepine acetate in pregnant women. In studies conducted in pregnant mice, rats, and rabbits, eslicarbazepine acetate did show developmental toxicities, including teratogenicity, embryolethality, and fetal growth retardation, at clinically relevant doses. Drug-induced liver injury ranging from mild to moderate elevations in transaminases (>3 times the upper limit of normal) to rare cases with concomitant elevations of total bilirubin (>2 times the upper limit of normal) have been reported with the use of eslicarbazepine. Overdose with eslicarbazepine acetate appears similar to its known adverse reactions and includes symptoms of hyponatremia, dizziness, nausea, vomiting, somnolence, euphoria, oral paraesthesias, ataxia, and diplopia. There is no specific antidote for eslicarbazepine acetate overdose and it should be treated primarily with supportive measures. If required, the drug may be removed by gastric lavage, partially by hemodialysis or inactivated with activated charcoal.
