有益效果
本发明的结晶 水合物 不同于 无水物的潮解使得在处理时要隔绝空气防止粘连等,而结晶水合物具有良好的滑动性,从而改善制剂的可操作性; 并使 制备的固体制剂 具有良好的溶出性能,使得其容易被吸收进入血液循环,改善生物利用度,并有利于快速发挥其作用。从另一个方面,使得其防止出现在进行无菌分装时不易因为吸潮而导致分装时产生堵塞使得装量发生差异导致剂量不足,从而带来产品的不合格,或因为不合格的产品没有被抽检到形成实际上的漏检,进而流入市场,在临床治疗中对患者的治疗代理负面的效果,或者因剂量不足危及病人的生命。或者在分装时,因为吸潮而导致整个生产线被迫暂停,严重降低设备的生产能力,大大增加工时费用等的隐患。此外,制备头孢地嗪钠无水物比头孢地嗪钠水合物的制备需要消耗更多的能量。
该抗菌组合药物并可用于原来对头孢地嗪钠水合物敏感较差但合并使用上述酶抑制剂后敏感性增强的革兰氏阳性或阴性细菌所致的感染性疾病,上述组合物适用于制备其所致的人或动物的呼吸系统、肝胆系统、五官、尿路感染、腹腔感染、盆腔感染、败血症、皮肤软组织感染、骨和关节感染、子宫附件炎、子宫内感染、子宫旁结缔组织炎、脑膜炎、淋病 等疾病的治疗或预防的药物中的应用。
