部分中文肝素钠处方资料（仅供参考） 产品名称 肝素钠 Heparin Sodium 肝素钠，别名为肝素、肝磷脂、Heparinar、Hepsal、Liguaemin、Lipo-Hepin、Pularin等，是一种含有硫酸基的酸性粘多糖类天然抗凝血物质。肝素是分子量大小各异的一簇酸性粘多糖混合物的统称，具有由六糖或八糖重复单位构成的线形链状分子，分子量在3,000到30,000Da之间，平均分子量15,000Da左右。肝素广泛分布于哺乳动物的肝、肺、心、脾、肾、胸腺、肠粘膜、肌肉和血液里。因此肝素可由猪肠粘膜、牛肺、猪肺提取。1996年疯牛病爆发后，世界卫生组织已禁止使用从犄角动物体内提取的肝素钠。 因其最初得自肝脏，故名肝素，现多由猪、牛、羊肠粘膜或猪、牛肺中提得，是一种粘多糖的硫酸酯。按干燥品计算，每1mg效价不得少于150单位。 性状 为白色或类白色粉末；有引湿性。在水中易溶。在水溶液中有强负电荷，能与一些阳离子结合成分子络合物。 药理 肝素钠在体内外均有抗凝血作用，可延长凝血时间、凝血酶原时间和凝血酶时间。现认为肝素钠通过激活抗凝血酶Ⅲ（atⅢ）而发挥抗凝血作用。 atⅢ是一种血浆α2球蛋白，它作为肝素钢的辅助因子，可与许多凝血因子结合，并抑制这些因子的活性。 因此影响凝血过程的许多环节： ①灭活凝血因子Ⅻa、Ⅺa、Ⅸa、Ⅹa、Ⅱa和Ⅷa； ②络合凝血酶原（Ⅱa）； ③中和组织凝血活素（Ⅲ）。肝素钠与atⅢ见结合后，可加速atⅢ且的抗凝血作用。 肝素钠在体内还有降血脂作用，这是由于它能活化和释放脂蛋白脂酶，使乳糜微粒的甘油三酯和低密度脂蛋白水解之故。 口服无效，须注射给药。静注后在血内均匀分布于白细胞和血浆，很快进入组织、胎盘和乳汁。vd为0.06l／kg。血浆蛋白结合率约为80％。在肝脏代谢，经肾排出。t1/2约为1小时，可随剂量增加而延长。 应用 （1）防治血栓形成和栓塞，如心肌梗塞、肺栓塞、血栓性静脉炎及术后血栓形成等。 （2）治疗各种原因引起的弥散性血管内凝血（dic），如细菌性脓毒血症、胎盘早期剥离、恶性肿瘤细胞溶解所致的dic，早期应用可防止纤维蛋白质和凝血因子的消耗。 （3）其他体内外抗凝血，如心导管检查、心脏手术体外循环、血液透析等。 用法 （1）静滴：成人首剂500o单位加入100ml　5％～10％葡萄糖溶液或0.9％氯化钠注射液中，在30～60分钟内滴完。需要时可每隔4～6小时重复滴注1次，每次5000单位，总量可达25000单位／日。为维持恒定血药浓度，也可每24小时10000～20000单位加于1000ml　5％葡萄糖溶液或0.9％氯化钠注射液中静滴，速度20滴／分。用于体外循环时，375单位／kg，体外循环超过1小时者，每kg体重加125单位。 （2）静脉或深部肌注（或皮下注射）：每次5000～10000单位。 注意 （1）用药过量可致自发性出血，表现为粘膜出血（血尿，消化道出血）、关节积血和伤口出血等，故用药期间应测定凝血时间或部分凝血活素时间（ptt），凝血时间＞30分钟或ptt＞100秒均表明用药过量。发现自发性出血应立即停药。严重出血可静注硫酸鱼精蛋白注射液中和肝素钠，注射速度以每分钟不超过20mg或在10分钟内注射50mg为宜。通常1mg鱼精蛋白在体内能中和100单位肝素钠。 （2）偶有过敏反应如哮喘、荨麻疹、结膜炎和发热等。长期用药可致脱发和短暂的可逆性秃头症、骨质疏松和自发性骨折。尚见短暂的血小板减少症。 （3）对肝素钠过敏、有出血倾向及凝血机制障碍者，患血小板减少症、血友病、消化性溃疡、严重高血压、颅内出血、细菌性心内膜炎、活动性结核、先兆流产或产后、内脏肿瘤、外伤及手术后均禁用肝素钠。妊娠妇女仅在有明确适应证时，方可用肝素钠。 （4）肌注或皮下注射刺激性较大，应选用细针头做深部肌肉或皮下脂肪组织内注射。 制剂 注射液：每支1000单位（2ml）；5000单位（2ml）；12500单位（2ml）。 贮法 遮光，在凉处保存。 Heparin Lock Flush Pronunciation: HEP-a-rin Generic Name: Heparin Lock Flush Brand Name: Generic only.
