Has the advantages of releasing drug effect as soon as possible, being beneficial to drug absorption, and covering mucosa with drugs. Most chewable tablets can also be swallowed, but this is not recommended. Although swallowing will not produce adverse reactions, the efficacy will be greatly reduced. In particular, antacids and chewing drugs for the treatment of digestive tract ulcers, such as: compound aluminum hydroxide (weishuping), sucralfate, aluminum magnesium carbonate, Gaiweiping, weishule, Lewei and so on. Because these drugs can be dispersed into tiny particles after chewing, they can cover the digestive tract mucosa to form a protective film after entering the stomach, so that the inflamed or ulcerated mucosa can heal as soon as possible. If the whole granule is swallowed, the drug cannot be quickly decomposed into small granules, and thus a protective film cannot be formed. Generally speaking, chewable tablets have no bitterness and taste acceptable to most people, so it is strongly recommended that you take them after chewing.
