On the function of tablet and bottle from the characteristics of drugs

Tablet is a tablet preparation made by evenly mixing drugs and excipients. Its properties are also different according to different drug components. Tablet bottle is a special package for holding tablet drugs, so how to choose the appropriate package according to the characteristics of drugs?

Moisture resistance: most tablets are greatly affected by humidity, air and microorganisms. The drugs after water absorption may be dissolved, moldy and fermented, and can not be reused. Such as aspirin, pancreatin tablets, compound licorice tablets, effervescent tablets, etc. Storage of such drugs requires placing desiccant in tablet bottles to absorb moisture and maintain drug stability.

Tightness: oxygen and carbon dioxide in the air will deteriorate drugs. For example, vitamin C tablets will turn yellow after oxidation. This kind of drugs have high requirements for the tightness of packaging. The bottle cap should be covered as soon as possible after use and should not be exposed to the air for a long time.

Shading: some tablets will undergo oxidation, reduction, hydrolysis and other reactions under the direct irradiation of light, resulting in discoloration and deterioration of drugs, resulting in reduced efficacy or toxicity. This kind of drugs shall be stored in brown tablet bottles, such as nitroglycerin tablets, aminophylline tablets, dipine antihypertensive drugs, etc.

The characteristics of tablet bottles, such as moisture resistance, sealing and shading, basically meet the storage needs of different tablets. Of course, before taking drugs, patients should carefully read the drug instructions and store them according to the specified conditions to avoid drug failure or deterioration due to improper storage.
