药房自制的滴眼液往往因橡胶塞处理不好,贮存较久后,引起胶塞脱落胶性絮状物、色素等,影响药液的澄明度。经我们多年实践,证明用乙醇、盐酸处理橡胶塞,效果较好,现介绍如下。将橡胶塞用水搓洗2～3次,除去表面灰尘等杂物,干后用95%乙醇在室温浸泡24小时,时加搅动或搓揉,取出用热蒸馏水搓洗至无乙醇味,然后以0.5%盐酸于室温浸泡4～5小时(冬天浸泡时间可延长24小时左右,视橡胶制品的质量而定)。倾去盐酸,用滤过的蒸馏水搓洗至 pH5～6即可。最后用滤过的蒸馏水煮沸半小时,
Pharmacy homemade eye drops are often handled due to poor rubber stopper, storage for a long time, causing plastic plug off plastic floe, pigments, etc., affect the clarity of the liquid. After years of our practice, proved that the use of ethanol, hydrochloric acid rubber plug, the effect is better, are described below. Rub the rubber stopper with water for 2 to 3 times to remove the surface dust and other debris, soak in 95% ethanol at room temperature for 24 hours after drying, add agitation or rubbing, remove and scrub with hot distilled water until no ethanol taste, then 0.5% Hydrochloric acid soak at room temperature for 4 to 5 hours (winter immersion time can be extended for about 24 hours, depending on the quality of rubber products). Dip hydrochloric acid, scrub with distilled water to pH5 ~ 6 can be. Finally, filtered distilled water for half an hour,
