Types of desiccants in effervescent tablet packaging

As a form of packaging with moisture-proof requirements, the effervescent tube not only needs to have excellent sealing performance, but also requires the stability of the internal environment to ensure the quality and effectiveness of the drug. In order to meet this challenge, its lid is usually equipped with a desiccant, whose function is to absorb internal moisture and keep the drug dry in the package.

The importance of ensuring drug quality

Solid drugs are often affected by moisture during production and storage. Even trace amounts of water molecules may cause changes or degradation in the drug, thereby affecting the purity and efficacy of the drug. In order to effectively maintain the stability of the drug and the safety of long-term storage, placing a desiccant inside the effervescent tube becomes a necessary measure.

Commonly used desiccant selection

Commonly used desiccant in effervescent tubes include silica gel, molecular sieves, and their mixtures. Silica gel has excellent hygroscopic properties and can effectively absorb moisture and maintain a dry environment. Molecular sieves are widely used because of their special microporous structure, which can selectively adsorb water molecules and maintain the stability of the drug. Sometimes a mixture of silica gel and molecular sieves is used to combine moisture absorption speed and adsorption capacity, and is formulated according to the characteristics of specific drugs to achieve good results.

Select the appropriate desiccant according to the characteristics of the drug

Different drugs have differences in their composition and chemical properties, so it is particularly important to choose the right desiccant. For example, for drugs that are particularly sensitive to moisture, it may be necessary to select a desiccant with a faster moisture absorption rate and stronger adsorption capacity to ensure that the high quality and effectiveness of the drug are maintained throughout the life cycle. Therefore, when drug manufacturers choose effervescent tube packaging, they need to conduct an accurate evaluation of the drug characteristics and take corresponding packaging design measures.

Desiccant in effervescent tubes plays a key role in ensuring the quality and stability of solid drugs. They effectively absorb and control internal moisture to keep the drug dry in the packaging, thereby ensuring the safety and effectiveness of the drug and providing patients with safer and more reliable drugs.
