id="Lacosamide.Introduction"><h3>Introduction</h3><p>Lacosamide is an amino acid derivative with a unique anticonvulsant activity that is used in combination with other agents as therapy of partial onset seizures. Lacosamide therapy is associated with a low rate of transient serum enzyme elevations and has been linked to rare instances of clinically apparent liver injury.</p></div><div id="Lacosamide.Background"><h3>Background</h3><p>Lacosamide (la koe' sa mide) is a functionalized amino acid derivative that appears to act by slow inactivation of voltage gated sodium channels in the central nervous system, which decreases the rate of neurotransmission and diminishes rapid, repetitive neuronal firing. Lacosamide was approved for use as an anticonvulsant in the United States in 2011 and current indications are for its use in partial-onset seizures in patients 4 years of age or above either alone or in combination with other anti-epileptic agents. Lacosamide is available in tablets of 50, 100, 150 and 200 mg under the brand name Vimpat. It is also available in solution as for oral (10 mg/mL) use and in an intravenous form (200 mg in single-use 20 mL vials) for short term use in adults when oral administration. The typical dose is 50 mg twice daily initially, with subsequent dose increases to an average of 200 to 400 mg daily. Side effects may include headache, dizziness, ataxia, blurred vision, nausea, fatigue and tremor.</p></div><div id="Lacosamide.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>In prelicensure clinical trials, addition of lacosamide to standard anticonvulsant therapy was reported to be associated with ALT elevations above 3 times the upper limit of normal (ULN) in 7 of 935 patients (0.7%) compared to none of 356 treated with placebo. A single case of hepatitis with jaundice during lacosamide therapy was also reported. Since approval, there have been rare isolated reports of clinically apparent liver injury associated with lacosamide used, but the clinical features suggested that hepatic ischemia or other anticonvulsants combined with lacosamide may have been responsible. The onset was within a few days to several months after starting and the presentation was with 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="Lacosamide.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>Lacosamide is metabolized by the liver, largely by CYP 2C19, 2C9 and 3A4, but has not been reported to have clinically significant drug interactions. Approximately 40% is excreted unchanged in the urine, and the metabolites of lacosamide are inactive. The mechanism of hepatic injury from lacosamide is not known, but may relate to a toxic or immunogenic metabolite.</p></div><div id="Lacosamide.Outcome_and_Management"><h3>Outcome and Management</h3><p>There is no information on the possible cross sensitivity to hepatotoxicity between lacosamide and other anticonvulsants, but its structure suggests that it would not have shared sensitivity to liver injury.</p><p>Drug Class: <a href="/books/n/livertox/Anticonvulsants/?report=reader">Anticonvulsants</a></p></div></div><div id="Lacosamide.PRODUCT_INFORMATION"><h2 id="_Lacosamide_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><div id="Lacosamide.BPI" class="box boxed-text-box whole_rhythm hide-overflow"><p>
