Among the commonly used drugs, some are enteric-coated tablets. The commonly used enteric-coated tablet is a kind of tablet that does not disintegrate in gastric juice, but can be disintegrated and absorbed in intestinal juice. The drug is made into enteric-coated tablets. It is to meet the needs of drug properties and treatment. Because many drugs are unstable under the acidic conditions of gastric juice, they are easy to decompose and fail or are irritating to the gastric mucosa; some drugs can only be better absorbed in the intestinal tract. In order to give full play to the therapeutic effect of drugs, these drugs are coated with a substance that can only be dissolved in alkaline intestinal fluid - enteric coating. Therefore, when using erythromycin enteric-coated tablets, midecamycin enteric-coated tablets, pancreatin enteric-coated tablets, amylase, multi-enzyme tablets and other drugs, the tablets should not be broken, chewed or ground into powder. Tablets to swallow. Some people find it difficult to swallow a capsule or tablet, especially older adults who have reduced saliva production and have more difficulty swallowing a capsule or tablet. Therefore, rinse the mouth before taking the medicine, or drink some warm water to moisten the throat, then put the tablet or capsule on the back of the tongue, take a sip of water and swallow it.

HPMC-P is broken down into two types, HP-55 and HP55S. HP-55 is insoluble at pH lower than 5.0. HP-55S is insoluble at pH lower than 5.5. HPMC-P helps make a drug released at a right place by delivering it to the intestine, which is vulnerable to gastric fluid, and the enteric coating helps users easily take the drug.
