Small measures for drug storage to prevent deterioration

Small measures for drug storage 1 Generally speaking, it is better to store the medicinal materials in the refrigerator, especially the valuable medicinal materials, such as the price of winterwort and bird's nest, which can prevent insects and moisture It should be noted that frequent opening and closing of refrigerators, water mist will soak drugs for a long time will make drugs deteriorate, so it is best to use fresh-keeping bags to wrap and tie drugs tightly when storing In addition, the decoction should also be put into the refrigerator, the longest storage time is 15 days 2 In order to prevent moth and mildew, we should use the method of "resist and store together", such as pepper price, star anise price, jade osmanthus price and some other herbs with pungent flavor together, which can prevent moth and mildew, such as pepper price and gecko price, seahorse price together, Danpi price and Huaishan, Baizhu price together, etc 3 Moistureproof some medicinal materials should be dried to remove moisture, and then put into sealed bottle caps for preservation to prevent discoloration and odor However, Beiqi, tangerine peel, angelica and Huaishan (yam) should not be exposed to the sun The exposure of Beiqi and Huaishan will change the color of medicinal materials, which can be used The method of "baking" is used for drying; the price of tangerine peel and angelica root will lose the smell of medicinal materials when exposed to the sun, so they should be stored in the refrigerator 4 In addition to the physical and chemical properties of the drug itself, as well as the crystal form, prescription process and excipients of the drug, the factors that affect the stability of the drug should be considered for the same drug Therefore, drugs of the same composition often have different packaging and storage conditions For example, the antiplatelet drug clopidogrel is divided into crystal type I and crystal type II The thermodynamic stability of drugs is different with different crystal types Type I is easy to return to damp and turn yellow in rainy days It must be moistureproof Therefore, even if you buy the same drug, you should see the label clearly 5 Establish a drug file and a drug identification card to classify drugs The reserved drugs can be divided into two categories: internal medicine and external medicine; and then the forms can be made according to the name, use, usage, dosage, precautions, expiration period, etc once necessary, the forms can be checked, which is convenient and safe When the medicine is disassembled and stored, the label shall be attached, indicating the name, specification and expiration date of the medicine Do not store the medicine without the label according to the memory Do not use the medicine with doubtful name and specification 6 Once every three months, check the medicine box to see whether the medicine is expired or deteriorated Every 3 months or so, it is better to check the family medicine box Once the medicine is found to be deteriorated, deliquescent, moldy or expired, it should be cleaned up in time 7 For the storage of syrup, oral liquid, mixture and other bottled drugs with high sugar content and prone to moldy fermentation of different dosage forms, you can only pour out as much as you need, and it is not suitable to pour them back, or contact the bottle mouth with the mouth to avoid pollution Eye drops, inhalers, sprays, cream and other drugs should not be contaminated when using drugs, so as not to pollute the remaining drugs Anesthetics, psychotropic substances such as morphine and sleeping pills should be locked and kept.
