The improper storage of the four types of drugs is prone to moisture

Good ice boron scattered, once used on the end of a block, but also changed the color; bought a short vitamin C effervescent tablets, actually swollen into a "strange thing." In wet and rainy weather, the drug administration department will receive similar consultations from many citizens.

According to experts, in the wet season, drugs are susceptible to moisture deterioration. Members should pay attention to the preservation of drugs and the timely clearing of medicine boxes. If they are found to be deteriorating, do not use them.

From the point of view of the characteristics of pharmaceutical preparations, the following medicines should be particularly noted for dry preservation:

First, granules and granules: This type of medicine is a dry granular (or lumpy) oral preparation made by adding fine powders or extracts of medicines into sugar powder and other auxiliary materials, such as commonly used "Banlangen granules", " Snape-D granules, etc. Such drugs are easily deliquescent and agglomerate in a humid environment, and effervescent granules in particular should be protected from moisture.

Second, powder: powder is a kind of powder (or more) made of evenly mixed preparations, such as the common "ice boron powder", "powder powder", "Dacconine powder" and so on. Because the surface area of ​​the powder is larger than that of general drugs, hygroscopicity is significant. Such drugs will undergo discoloration, agglomeration, reduced efficacy, and microbial growth after exposure to moisture, so moisture protection is an important measure to ensure the quality of powders.

Third, effervescent tablets: effervescent tablets are placed in the right amount of water before use, rapid disintegration and dissolution after use, such as "vitamin C effervescent tablets" and so on. In the preparation of this dosage form, a component of auxiliary solubility is added. Such components generate gas in the presence of water, causing the effervescent tablet to swell, deform, and break. Therefore, it is very prone to deliquescence and should be kept dry.

Fourth, Chinese herbal medicines: traditional Chinese herbal medicines generally do not have special packaging, if not properly preserved, it is more prone to mildew, infestation, discoloration, flooding and other phenomena, which lead to deterioration.

Therefore, after the drug is used, the original packaging should be restored as far as possible and the drug should be kept in a closed state. Households should use plastic glass bottles or sealed plastic boxes as much as possible to avoid the use of paper bags, paper boxes, plastic bags and other moisture-free packaging materials, for too humid environment or more hygroscopic drugs, desiccants can be preserved.
