其他信息
- 制备方法:1,丙炔醇法:由乙炔与甲醛在加压(1.96~2.3MPa)下,进行催化(乙炔铜为催化剂)乙炔化反应,制成丙炔醇。再经催化氧化 (2.36MPa)得丙炔醛,同时与二乙胺加成得二乙胺基丙烯醛。然后与磺胺胍缩合,经酸析,精制而成磺胺嘧啶成品。 2,乙烯基乙醚法:由乙炔和乙醇蒸气在氢氧化钾-氧化钙催化下进行加成,生成乙烯基乙醚,然后与二甲基甲酰胺在三氯化磷存在下缩合,再与磺胺胍在甲醇钠存在下环合、酸析而成磺胺嘧啶成品。
- 用途一:磺胺类药,用于治疗由溶血性链球菌、肺炎球菌、脑膜炎球菌、淋病双球菌、大肠杆菌所致的感染
- 上游原料:乙醇 --> N,N-二甲基甲酰胺 --> 甲醇钠 --> 三氯化磷 --> 二乙胺 --> 乙烯基乙醚 --> 碳化钙 --> 2-丙炔-1-醇 --> 维生素 B1 --> 磺胺脒
- 用途三:为磺胺类药的优良品种,抗菌作用较强,疗效较好,吸收较快,排泄较慢,在血中有效浓度较高。临床用于治疗上呼吸道感染。流行性脑膜炎、中耳炎、疖痈、产褥热、尿道感染及急性菌痢等。
- 磺胺类药物:磺胺嘧啶 又称磺胺哒嗪、地亚净,目前是我国临床上常用的一种磺胺类药物。本品对溶血性链球菌、葡萄球菌、脑膜炎双球菌、肺炎球菌、淋球菌、大肠杆菌、痢疾杆菌等敏感细菌以及沙眼衣原体、放线菌、疟原虫、星形奴卡菌和弓形虫等微生物均有抑制作用。磺胺嘧啶的优点是血中有效浓度较高,血清蛋白结合率低,药物易于渗入脑脊髓液,为治疗流行性脑膜炎的首选药物,但近年来脑膜炎双球菌对磺胺药的耐药菌株有所增加(国内报告20%,国外报告33%对本品耐药)。对本品耐药者,可用青霉素治疗。本品缺点为在尿路中较易析出结晶,因而需同服碳酸氢钠。近年来研究表明,其半寿期为17小时,故可属中效磺胺药,每日给药二次即可。但一般仍作短效使用。临床常用于治疗流行性脑脊髓膜炎、上呼吸道感染、流行性脑膜炎、中耳炎、痈疖、产褥热、鼠疫、局部软组织或全身感染、泌尿道感染及急性菌痢,尚可用于呼吸道感染、肠道感染、伤寒等。
- 化学性状:白色或类白色结晶或粉末,无臭,无味,遇光渐渐变暗色。几不溶于水,溶于沸水(1∶60),微溶于乙醇和丙酮,不溶于氯仿和乙醚,易溶于稀盐酸、氢氧化钠溶液或氨溶液。熔点252~256℃(同时分解)。其钠盐为白色结晶性粉末,无臭,味微苦。遇光渐变棕色。久置潮湿空气中,即缓缓吸收二氧化碳,析出磺胺嘧啶。易溶于水,微溶于乙醇,不溶于氯仿和乙醚。10%水溶液pH为9.5~10.5。
- 不良反应:1,有肾损害。本品的乙酰化率低,本品和其乙酰化物在尿中溶解度小,在尿液偏酸性时易析出结晶,损伤肾小管及其他尿路的上皮细胞而引起结晶尿、血尿、蛋白尿,严重者可致尿闭或尿毒症。 2,造血系统反应包括粒细胞减少、急性溶血性贫血、再生障碍性贫血、血小板减少性紫癜等。 3,胃肠道反应有恶心、呕吐等。偶可见黄疸、肝脾肿大。新生儿、早产儿可引起黄疸,甚至出现核黄疸。 4,泌尿系统的损害:由于原型磺胺及乙酰磺胺主要经肾排泄,在尿中浓度较高,如尿液偏酸,其溶解度降低,可在肾小管、肾盂、输尿管或膀胱内析出结晶,引起结晶尿、血尿、管型尿、尿痛、尿少甚至尿闭等症状。 5,过敏反应常见有皮疹、药热等,严重者可出现剥脱性皮炎、渗出性多形红斑等,多在用药7~10天出现。也可见光敏性皮炎。
- 药动学:本药口服后易吸收(可吸收给药量的70%以上),但吸收较缓慢。单次口服2g后,3~6小时达血药浓度峰值,游离血药浓度峰值约为30~60μg/ml。药物吸收后广泛分布于全身组织及胸膜液、腹膜液、滑膜液、房水、唾液、汗液、尿液、胆汁中。本药易透过血-脑脊液屏障,也能进入乳汁和通过胎盘屏障。脑膜无炎症时,脑脊液中药物浓度约为血药浓度的50%,脑膜有炎症时,脑脊液中药物浓度可达血药浓度的50%~80%。 本药血浆蛋白结合率低,约为38%~48%。肾功能正常者清除半衰期约为10小时,肾衰竭者可达34小时。磺胺嘧啶药物主要在肝脏经过乙酰化代谢而失效,其次是与肝脏中的葡萄糖醛酸结合而失效。药物主要经肾小球滤过排泄,给药后48~72小时内以原形药物经尿中排出给药量的60%~85%。此外,另有少量药物经粪便、乳汁、胆汁中排出。血液透析可部分清除药物,但腹膜透析不能有效清除药物。
