　　Powder is a powdery preparation made by uniformly mixing one or more drugs. Since the surface area of the powder is larger than that of other dosage forms, its hygroscopicity is more remarkable.

　　3. Effervescent tablets

　　The effervescent tablet is a dosage form of medicine added with solubilizing ingredients in its production, so it will generate gas when it encounters water, causing the effervescent tablet to swell, deform, and rupture, so it is very easy to deliquesce and deteriorate.
