在200毫克/公斤以下,严重的卡巴马西平毒性不常见. 目前的指导方针表明毒性超过50毫克/公斤是过于保守的,因为严重的卡巴马西平过量反应在这个门以下是罕见的.
科学领域:
- 毒理学 毒理学 毒理学
- 药理学 药理学是指药理学的学科.
- 紧急医疗 紧急医疗
背景情况:
- 过量服用卡巴马西平可能会导致剂量依赖性毒性.
- 现有的资源表明严重毒性发生在50mg/kg以上,缺乏确的证据.
研究的目的:
- 评估摄入卡巴马西平剂量与临床毒性之间的关系.
- 为了确定一个更准确的卡巴马西严重毒性值.
主要方法:
- 对摄入卡巴马西>2,000毫克的患者进行了回顾性审查.
- 数据提取包括人口统计,摄入细节,临床影响和管理.
- 严重的毒性定义为昏迷 (GCS <9),发作或低血压 (SBP <90 mmHg).
主要成果:
- 在42名患者中出现了69例;中位数剂量为113毫克/公斤.
- 严重的毒性 (昏迷,,低血压) 发生在摄入>113 mg/kg的患者中.
- 摄入<100毫克/千克时没有报告严重毒性;低于200毫克/千克时不常见.
结论:
- 在200毫克/公斤以下,严重的卡巴马西平毒性不常见.
- 广泛引用的严重毒性50mg/kg的门似乎过于保守.
- 更高的摄入剂量 (>200 mg/kg) 与常见的严重毒性有关.
