Eslicarbazepine (BIA 2-194; BIA-2194; Aptiom; Zebinix) is a dual inhibitor of voltage-gated sodium channel blocker and β-Secretase approved for use as an antiepileptic drug for partial-onset seizures.
| ln Vivo |
Chemically similar to carbamazepine, escicarbazepine is an anti-epileptic medication with a better safety record. Eslicarbazepine acetate serves as a prodrug for eslicarbazepine (S-licarbazepine), a voltage-gated sodium channel and β-secretase dual inhibitor [1][2].

| Toxicity/Toxicokinetics |
Hepatotoxicity
In premarket clinical trials, it was reported that adding esilicarzepine to standard antiepileptic therapy resulted in a small number of patients experiencing ALT levels exceeding three times the upper limit of normal (ULN) (Probability score: D (likely a rare cause of clinically significant liver injury)). Pregnancy and Lactation Effects ◉ Overview of Use During Lactation There is currently no information regarding the use of esilicarzepine during lactation. However, esilicarzepine is the active metabolite of oxcarbazepine. Limited information suggests that oxcarbazepine is not expected to have any adverse effects on breastfed infants, especially those older than 2 months. Infant lethargy, weight gain, and developmental milestones should be monitored, especially in smaller, exclusively breastfed infants and in combination with other medications. Anticonvulsant ◉ Effects on Breastfed Infants There is currently no specific information on mothers taking esilicarzepine. Please refer to the LactMed record on oxcarbazepine for relevant information. ◉ Effects on lactation and breast milk As of the revision date, no relevant published information was found. |

| Additional Infomation |
(S)-MHD is a dibenzoxazole drug. Eslicarbazepine is an antiepileptic drug, marketed as eslicarbazepine acetate. Eslicarbazepine's mechanism of action is as a cytochrome P450 3A4 inducer and cytochrome P450 2C19 inhibitor. Its physiological effects are achieved by reducing disordered electrical activity in the central nervous system. Eslicarbazepine is an aromatic anticonvulsant, similar to oxcarbazepine, and is often used in combination with other antiepileptic drugs to treat partial seizures. Transient elevations of serum enzymes during eslicarbazepine treatment are rare but have been associated with rare cases of clinically significant liver injury. See also: eslicarbazepine acetate (its active ingredient). The exact mechanism of action of eslicarbazepine is unclear, but it is believed to be related to the inhibition of voltage-gated sodium channels.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (8.18 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (8.18 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
