片丸剂包了糖衣,可以防止氧化,保持药效,并能遮盍臭味,增加美观。关于包糖衣的一般操作,在一些制剂学中均有记载,本刊也有详细的介绍,兹不赘述。现在只将我们在包糖衣操作中所遇到的一些个别问题的解决办法,介绍如下: 一 (正朿)松的片剂在膠衣層里的处理包膠衣原则的操作,都须層層干燥,就是说,第一次洒入的膠漿,不宜过多,以能润湿片面为宜。洒入膠漿之后,即用手轻快地搅拌,使之迅速均匀地分佈于每个片上,并趁着片面未干,马上投入适量的滑石粉。(不可等到收汗时投粉,因为这样膠漿中的大部份水份,有被药片吸收的可能,容易促使药片变质。如对氨基水楊 Pills coated with sugar coating can prevent oxidation, maintain drug efficacy, and can conceal odor and increase beauty. The general operation of icing is documented in some preparations. This publication also has detailed descriptions. Now only the solutions to some of the individual problems we encountered during the icing process are described below: The processing of a tablet in a gel coat layer must be layered Drying, that is to say, the glue that is sprayed for the first time, should not be too much. After being sprayed into the mortar, stir it by hand gently, so that it can be quickly and evenly distributed on each piece, and put a proper amount of talcum powder immediately after the piece is still dry. (Do not wait until the powder is collected during sweating, because most of the water in the mortar may be absorbed by the tablet, which can easily cause deterioration of the tablet.
