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. |

(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.

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
