乙琥胺是治疗失神性癲癇（英语：Absence seizure）的口服药物^[4]。可以单独使用，也可以与其他抗癲癇藥品（英语：Anticonvulsant）（如：丙戊酸）併用^[4]。

副作用一般很小^[5]。常见的副作用包括食欲不振、腹痛、腹泻和疲倦^[4]。严重的副作用包括自殺想法（英语：Suicidal ideation）、血球减少（英语：Cytopenia）和红斑狼疮^[4] ^[5]。目前寫的怀孕期或 3 岁以下的安全仍不清楚^[4]。乙琥胺属于丁二酰亚胺类药物。確定的作用機轉並不清楚^[4]。

乙琥胺于 1960 年在美国取得医疗許可^[4]。名列世界卫生组织基本药物标准清单^[6]。已有學名藥流通於市^[4]。截至 2004 年，世界上大多数地区都已普遍可得^[7]。但至 2019 年，由于美国的統一定價（英语：Price fixing）或价格操纵的問題，這個药物在许多国家的取得都受到限制^[8] ^[9] ^[10]。
