id="_Eslicarbazepine_OVERVIEW_">OVERVIEW</h2><div id="Eslicarbazepine.Introduction"><h3>Introduction</h3><p>Eslicarbazepine is an aromatic anticonvulsant similar to oxcarbazepine that is used in combination with other antiepileptic agents as therapy of partial onset seizures. Eslicarbazepine is associated with a low rate of transient serum enzyme elevations during therapy and has been implicated in rare instances of clinically apparent liver injury.</p></div><div id="Eslicarbazepine.Background"><h3>Background</h3><p>Eslicarbazepine (es" li kar baz' e peen) is an aromatic anticonvulsant related in structure and activity to oxcarbazepine. Its mechanism of action is unknown but, like other carboxamides, eslicarbazepine is believed to inhibit voltage-gated sodium channels and thereby slow neurotransmission and interrupt the rapid, repetitive firing that is characteristic of epilepsy. Eslicarbazepine was approved for use in the United States in 2013 as an anticonvulsant to be used alone or in combination with other agents in the therapy of partial onset seizures. Eslicarbazepine is available in tablets of 200, 400, 600 and 800 mg under the brand name Aptiom. The recommended initial dose in adults is 400 mg once daily, which can be increased to 800 to 1600 mg once daily based upon tolerance and effect. The recommended initial doses in children are 200 to 400 mg once daily based upon body weight with maintenance dosages ranging from 400 to 1200 mg. Side effects may include headache, dizziness, ataxia, blurred vision, nausea, fatigue and tremor. Rare, but potentially serious adverse events include hyponatremia, suicidal ideation or behavior and hypersensitivity reactions including DRESS and Stevens Johnson syndrome.</p></div><div id="Eslicarbazepine.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>In prelicensure clinical trials, addition of eslicarbazepine to standard anticonvulsant therapy was reported to be associated with ALT elevations above 3 times the upper limit of normal (ULN) in a small proportion of patients (&#x0003c;1.0%). A single case of hepatitis with jaundice during eslicarbazepine therapy was also reported. Since approval, there have been rare isolated reports of clinically apparent liver injury associated with eslicarbazepine used, but the clinical features suggested that hepatic ischemia or other anticonvulsants combined with eslicarbazepine may have been responsible. The onset was within a few days to several months after starting the anticonvulsant, and the presentation was characterized by a hepatocellular pattern of serum enzyme elevations, one case being asymptomatic and mild and the other severe. In both instances there was rapid recovery.</p><p>Likelihood score: D (possible rare cause of clinically apparent liver injury).</p></div><div id="Eslicarbazepine.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>Eslicarbazepine is metabolized by the liver, largely by CYP 2C19, but has not been reported to have significant drug interactions. The mechanism of hepatic injury from eslicarbazepine is not known, but may relate to a toxic or immunogenic metabolite.</p></div><div id="Eslicarbazepine.Outcome_and_Management"><h3>Outcome and Management</h3><p>Most instances of liver injury associated with eslicarbazepine have been transient and mild but more severe cases have been reported. The product label recommends baseline evaluation of liver tests and prompt discontinuation if jaundice or symptoms of liver disease arise. There is no information on the possible cross sensitivity to hepatotoxicity between eslicarbazepine and other anticonvulsants, but its structure would suggest that it would havel cross sensitivity to hypersensitivity reactions with oxcarbazepine and possibly partial cross sensitivity to other aromatic anticonvulsants such as phenytoin, carbamazepine and lamotrigine.</p><p>Drug Class: <a href="/books/n/livertox/Anticonvulsants/?report=reader">Anticonvulsants</a></p></div></div><div id="Eslicarbazepine.PRODUCT_INFORMATION"><h2 id="_Eslicarbazepine_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><div id="Eslicarbazepine.BPI" class="box boxed-text-box whole_rhythm hide-overflow"><p>
