Enteric-coated capsules, generally speaking, are capsules that can be dissolved and absorbed in the small intestine of the human body. The so-called enteric-coated capsule is actually just a special medicinal polymer material added to the capsule shell or specially treated to make it insoluble in gastric juice, and only disintegrate and dissolve in intestinal juice. The capsule will not be dissolved in the stomach, or in soaked water or even boiling water.
"Enteric-coated capsules need to be exposed to alkaline liquid in the intestines to dissolve, whereas stomach acid is acidic, so the capsules will not be dissolved in the stomach. If the enteric-coated capsule dissolves in the stomach, it may cause damage to the stomach. "
Now the capsules commonly seen in clinical practice are gelatin capsules, and the composition is gelatin. Pharmaceutical gelatin is a high-grade gelatin product made of animal skin, bone and tendon through complex physical and chemical treatment, which has the physical characteristics of high viscosity, high freezing power and easy freezing.
