英文药名: Salazopyrin (Sulfasalazine Enteric Coated Tablets) 中文药名: 柳氮磺胺吡啶肠溶片 品牌药生产厂家: Pfizer 药品名称 柳氮磺吡啶 0.5g 本品为磺胺类抗菌药。属口服不易吸收的磺胺药,吸收部分在肠微生物作用下分解成5-氨基水杨酸和磺胺吡啶。5-氨基水杨酸与肠壁结缔组织络合后较长时间停留在肠壁组织中起到抗菌消炎和免疫抑制作用,如减少大肠埃希菌和梭状芽孢杆菌,同时抑制前列腺素的合成以及其他炎症介质白三烯的合成。因此,目前认为本品对炎症性肠病产生疗效的主要成分是5-氨基水杨酸。由本品分解产生的磺胺吡啶对肠道菌群显示微弱的抗菌作用。本品为肠溶糖衣片,除去包衣后显棕色。 口服后少部分在胃肠道吸收,通过胆汁可重新进入肠道(肠-肝循环)。末被吸收的部分被回肠末段和结肠的细菌分解为5-氨基水杨酸与磺胺吡啶,残留部分自粪便排出。5-氨基水杨酸几乎不被吸收,大部分以原形自粪便排出,但5-氨基水杨酸的N-乙酰衍生物可见于尿内。磺胺吡啶可被吸收并排泄,尿中可测知其乙酰化代谢产物。磺胺吡啶及其代谢产物也可出现于母乳中。 主要用于炎症性肠病,即Crohn病和溃疡性结肠炎。 口服成人常用量:初剂量为一日2~3g,分3~4次口服,无明显不适量,可渐增至一日4~6g,待肠病症状缓解后逐渐减量至维持量,一日1.5~2g。 血清磺胺吡啶及其代谢产物的浓度(20~40μg/ml)与毒性有关。浓度超过50μg/ml时具毒性,故应减少剂量,避免毒性反应。 对磺胺类药物过敏者、孕妇、哺乳期妇女、2岁以下小儿禁用。 1.缺乏葡萄糖-6-磷酸脱氢酶、肝功能损害、肾功能损害患者、血卟啉症、血小板、粒细胞减少、血紫质症、肠道或尿路阻塞患者应慎用。 当每天用量达到或超过4g或血清药物浓度超过50mg/ml,不良反应或毒性反应增多。 1.与尿碱化药合用可增强磺胺药在碱性尿中的溶解度,使排泄增多。 规格: Sulfasalazine is a medication used to treat inflammatory bowel disease such as ulcerative colitis, proctitis, and Crohn's Disease. It helps to control symptoms by reducing inflammation in the bowel. It also can be used to treat rheumatoid arthritis when treatment with other medications has not helped.

Should not be used by people in whom acute asthmatic attacks, hives, rhinitis or other allergic symptoms are brought on by ASA or other nonsteroidal anti-inflammatory agents. Pregnancy Breastfeeding Side Effects Side effects involving the stomach are drastically reduced when the enteric coated tablets are used.
