    為的衍生物，是一種抗纖溶的止血藥物，止血機制與、相同，但作用更強，強度是的7～10倍、的2倍，而毒性相近。
化學結構與賴氨酸相似，能競爭性阻抑纖溶酶原在纖維蛋白上吸附，防止其激活，保護纖維蛋白不被纖溶酶所降解和溶解，終達到止血效果。適用于治療急性或慢性、局限性或全身性原發(fā)性纖維蛋白溶解亢進所致的各種出血，如產(chǎn)科出血，出血、前列腺肥大出血、血友病、肺結核喀血、胃出血、肝、肺、脾等內臟手術后的出血等；也可用于手術時異常出血等。
臨床上對蟲咬癥、濕疹皮炎、單純性紫癜、慢性蕁麻疹、人工性蕁麻疹、中毒疹和藥疹等效果顯著，對紅皮病、硬皮病、SLE、多形紅斑、帶狀皰疹和斑禿亦有一定療效，對遺傳性血管性水腫療效亦較好。治療黃褐斑一般用藥3周左右見效，5周顯效， 60 d一療程。每次口服0.25～0.5g，一日3～ 4次。少數(shù)患者可發(fā)生惡心、疲乏、瘙癢、腹部不適和腹瀉等副作用，停藥后癥狀即消失。
