[L49191][L49196][L49201]
In Canada, it is reserved for use in adults.
[L49206]
It is also used as an adjunctive therapy in the treatment of primary generalized tonic-clonic seizures in patients four years of age and older.
[L49191][L49201]
The extended-release capsules of lacosamide are indicated for the treatment of partial-onset seizures in adults and in pediatric patients weighing at least 50 kg.
[L49196]
Known interactions with other medications. Always consult a healthcare professional.
Showing 50 of 993 interactions
[L49171]
Dizziness, nausea, and seizures (generalized tonic-clonic seizures, status epilepticus) were observed at doses greater than 800 mg, which is twice the maximum recommended daily dose. Cardiac conduction disorders, confusion, decreased level of consciousness, cardiogenic shock, cardiac arrest, and coma have also been observed.
[L49191]
Fatal overdoses have occurred with lacosamide. As there is no specific antidote for overdose with lacosamide, standard decontamination procedures should be followed.
General supportive care of the patient is indicated including monitoring of vital signs and observation of the clinical status of patient. Standard hemodialysis procedures result in significant clearance of lacosamide (reduction of systemic exposure by 50% in four hours). Hemodialysis may be indicated based on the patient's clinical state or in patients with significant renal impairment.

How the body processes this drug — absorption, distribution, metabolism, and elimination
The Tmax ranges from one to four hours. Steady-state plasma concentrations are achieved after three days of twice-daily repeated administration. The pharmacokinetics of lacosamide are dose-proportional over the dose range between 100 and 800 mg, and time-invariant, with low inter- and intra-subject variability.
The major O-desmethyl metabolite of lacosamide has a longer Tmax that ranges from 0.5 to 12 hours.
[L49191]
After intravenous administration, Cmax is reached at the end of infusion. The 30- and 60-minute intravenous infusions are bioequivalent to the oral tablet. For the 15-minute intravenous infusion, bioequivalence was met for AUC0-tz but not for Cmax.
The point estimate of Cmax was 20% higher than Cmax for oral tablet and the 90% CI for Cmax exceeded the upper boundary of the bioequivalence range. In a trial comparing the oral tablet with an oral solution containing 10 mg/mL lacosamide, bioequivalence between both formulations was shown. A single loading dose of 200 mg approximates steady-state concentrations comparable to the 100 mg twice-daily oral administration.

Nav1.7 plays a crucial role in controlling the excitability and action potential propagation from nociceptor neurons, thereby contributing to the sensory perception of pain PMID:17145499 PMID:17167479 PMID:19369487 PMID:24311784

In some secretory cell types, it also participates in cell excitability through membrane depolarization and regulates cells responsiveness to stimuli triggering secretion. For instance, it controls the release of serotonin/5-hydroxytryptamine by enterochromaffin cells and is required for both glucagon- and glucose-induced insulin secretion in pancreatic endocrine cells (By similarity)
