With the changing market demand, medical bottle caps gradually have more diversified functions on the basis of sealing, such as moisture resistance. This special cover is mainly used for effervescent tablets, candy tablets and other drugs that require high moisture resistance. What is its design principle? Generally, desiccant will be placed inside the package for drugs that need moisture-proof preservation. The common way is to place desiccant in bags inside the medical plastic bottle. The moisture-proof medical bottle cap makes use of the space on the top of the cap. A small drug bin is designed on the top of the cap to store silica gel and molecular sieve desiccant. This design saves space on the one hand, but also can avoid the risk of children eating desiccant by mistake. The desiccant selected for this cover is mainly silica gel, molecular sieve or an equal proportion mixture of the two

Tablet medicine bottles are commonly used packages for storing various tablets, capsules or pills. In order to ensure the dryness of drugs, desiccants are usually placed inside the bottles to absorb moisture. But if the drugs are unsealed, will the desiccants be thrown away or retained? Generally, medicine bottles have certain hygroscopicity. When the environmental humidity is high, tablets, capsules, pills, etc. may absorb moisture in the air, causing deliquescence, deterioration, etc. of drugs, thus affecting the stability of drugs. In order to avoid deliquescence and keep the medicine dry, desiccant is often put in the tablet bottle. The commonly used medical desiccants are mainly silica gel, which is a transparent or milky white granular solid, has an open porous structure, strong adsorption, and can adsorb a variety of substances. When the tablet bottle is opened, the medicine in the bottle will directly contact with the outside air

Tablets are common dosage forms in drugs. They can be divided into controlled release tablets, sustained release tablets and other types according to different preparation processes and drugs. What are the characteristics of different tablets and what are the requirements for tablet bottles? Controlled release tablets and sustained release tablets are actually relatively special pharmaceutical preparation technologies. The sustained-release tablet literally means slow release. It can be released slowly in the human body, maintain a certain blood concentration for a long time, play a relatively long-term role, and reduce the number of drug administration to a certain extent. Under the same treatment effect, ordinary tablets may need to be taken three or four times a day, while sustained-release tablets are usually given once or twice a day, which can facilitate patients to a certain extent and improve their compliance. For controlled release tablets, it can not only slow the drug releas
