Drug moisture-proof packaging refers to the packaging with special moisture-proof function, which is mainly used for drugs that are very sensitive to water molecules. With the launch of new crown treatment drugs such as Pfizer's Paxlovid (Paxlovid) and Merck's Molnupiravir (Monupavir), the dawn of the new crown epidemic that has swept the world will appear. So, what important role will moisture-proof packaging play in pharmaceuticals?
At present, the new crown treatment drugs that have been marketed are mainly oral small-molecule drugs. The structure of small-molecule drugs has good spatial dispersion, and their chemical properties determine their good drug-forming properties and pharmacokinetic properties. These characteristics make small molecule drugs show great advantages in the drug development process and other drug fields, and the development of small molecule drugs is increasingly favored by the market. On the other hand, the dosage forms of these drugs are mostly tablets or capsules, which require very high moisture resistance of the packaging.
Tablets and capsules are very easy to absorb water molecules, causing deliquescence, adhesion, etc., affecting the therapeutic effect of drugs, and even endangering the health and safety of patients. Therefore, when choosing packaging, moisture-proof function is an element that pharmaceutical companies focus on. Drug moisture-proof packaging is a package with a desiccant. The desiccant can absorb the water molecules inside the package and maintain the stability of the drug within the validity period. It has become the main packaging form of tablets and capsules.
Preventing drugs from getting wet is the basic function of drug moisture-proof packaging. With the continuous improvement of packaging design and production technology, this kind of packaging has gradually equipped with child-proof and anti-theft functions, providing more security for drugs.
