This report describes the occurrence of generalised seizures in a 42-year-old woman who presented to hospital after deliberate lamotrigine overdose. Seizure activity was promptly terminated after intravenous benzodiazepine administration, and the patient subsequently made a complete recovery. Serum lamotrigine concentration was 30 mg/l at 1.3 h post-ingestion, which is substantially higher than the therapeutic reference range; the estimated elimination half life was 18.3 h. This case reminds us that lamotrigine toxicity may provoke generalised seizures in susceptible individuals.
本报告描述了一名42岁女性在故意过量服用拉莫三嗪后出现全身性癫痫发作的情况。静脉注射苯二氮䓬后,癫痫活动迅速终止,患者随后完全康复。摄入后1.3小时血清拉莫三嗪浓度为30mg/L,远高于治疗参考范围;估计消除半衰期为18.3小时。该病例提醒我们,拉莫三嗪毒性可能在易感个体中引发全身性癫痫发作。
