金霉素又称氯四环素,其盐酸盐溶于水,游离碱基特别是钙盐难溶于水。为四环素类抗生素,是在放线菌的培养液中发现的抗菌物质。可以杀 灭立克次体、支原体、衣原体、非典型分枝杆菌以及螺旋体等,适用于敏感金黄色葡萄球菌、化脓性链球菌、肺炎链球菌等革兰阳性菌及流感 嗜血杆菌等敏感革兰阴性菌所致浅表眼部感染的治疗,但同时也可用于其他部位敏感菌感染的治疗。

金霉素眼膏适应症及用法:结膜炎:俗称红眼病,可先用温水清除分泌物后,涂少许本品,闭眼休息片刻,让药物充分发挥作用,1天3次,晚上临睡前再涂1次。
麦粒肿:俗称偷针眼,发病后切勿用手挤压,以避免引起其他并发症。尚未形成脓肿前,热敷疗效很好。用热毛巾热敷20分钟,接着涂金霉素 眼膏,闭眼休息片刻。一天3次。
口角糜烂:口角出现糜烂时,可服用维生素B2,同时用棉签蘸温开水清洗伤口,揩干,再抹上本品,就可加快愈合。一般三天即可好转。
疖肿:当鼻黏膜有小疖胀痛时,可用药棉蘸取金霉素眼膏涂于鼻腔处,并轻压鼻子,促使疖肿吸收,加速痊愈,其他部位的疖肿也可同样使用 。
口角及手足干裂:先用热水洗净擦干,再涂少许本品,手足部分需用胶布固定,可加快伤口愈合。

金黄色结晶性粉末,无臭,味苦。熔点168-169℃(分解)。极微溶于水,溶于盐溶液。盐酸盐微溶于甲醇、水、乙醇,不溶于丙酮、乙醚、氯仿。在空气中稳定,遇光颜色渐暗。
