本发明陈述了控制肝素水介作用,制得新的口服有效抗凝剂的方法。发明的基础——抗凝剂广泛地利用于阻止或延缓动物血管内血液凝固造成血栓性静脉炎和血栓.或者造成肺周围,冠状动脉的梗塞。目前兽医、医生应用的主要抗凝剂是肝素,肝素以针剂形式被应用.而香豆素类型的化合物却口服有效。肝素的活性作用迅速.香豆素药物需要一个诱导过程(大约(由攵)小时),然后在一个较长的时期内有效果,目前处理的方法是要迅速抗凝的.采用 The present invention states a method of controlling the heparin water-mediated effect to produce a new orally active anticoagulant. Foundations of the Invention - Anticoagulants are widely used to prevent or delay blood coagulation in animals resulting in thrombophlebitis and thrombosis, or infarction of the lungs and coronary arteries. At present veterinarians, the main anticoagulant used by doctors is heparin, which is administered in the form of an injection, whereas the coumarin-type compound is orally available. The active heparin has a rapid effect. The coumarin drug requires an induction process (approximately (from 攵) hours) and then takes effect over a longer period of time, with the current approach being rapid anticoagulation
