Product Introduction
Bioactivity
| 名称 | Polymyxin B Sulfate |
| 描述 | Polymyxin B Sulfate (Poly-RX) is a mixture of polymyxins B1 and B2, obtained from Bacillus polymyxa strains. They are basic polypeptides of about eight amino acids and have cationic detergent action on cell membranes. Polymyxin B Sulfate (Poly-RX) is used for infections with gram-negative organisms, but may be neurotoxic and nephrotoxic. |

文献和实验成分 胰酶消化酪蛋白胨 15g 酵母膏 10g 柠檬酸铁 0.5g 琼脂 15g 蒸馏水 1000mL 10%亚硫酸钠水溶液(新配) 5mL 0.12%多粘菌素B硫酸盐水溶液 10mL 1.2%磺胺嘧啶钠水溶液 10mL pH7.0 制法 :前面五种成分配合后加热溶解
发现于多粘杆菌(Bacillus polymyxa)培养液中的抗菌性多肽,有A、B、C、D、E等五种。抗菌谱相互类似而范围宽广,特别对革兰氏阴性细菌作用颇强,毒性较弱。口服时不能吸收,但皮下或肌肉注射很快就转移到血液中去,在3-16小时保持较高的血中浓度。多粘菌素A用于治疗幼儿的重症百日咳可获很好效果。能使金黄色葡萄球菌及大肠杆菌的R型菌体凝集,并形成核糖核酸和不溶性盐类。多粘菌素B对肾的损害较A、 D两类为少,因此作为点眼药应市,对细菌性眼炎有效。
,每日1~2次。 硫酸多粘菌素B(polymyxin B sulfate)成人50~100万单位/日,儿童1.0~2.0万单位/日,分2~3次肌内注射或静脉滴注,疗程一般不超过7~14天,鞘内注射,成人1万单位/次,儿童5,000单位/次。 硫酸多粘菌素E(polymyxin E sulfate,colistin sulfate)肌内注射,成人100~150万单位/日,儿童1.5~2.5万单位/kg/日,分2~3次。静脉滴注,成人50~100万单位/日,分2次;儿童1.5~
