HPMC antacid hollow capsule is a plant capsule that does not dissolve in the human stomach but dissolves in the intestinal tract. It is also called a Plant enteric capsule.We mainly aim at drugs that need to be dissolved and absorbed in the intestines, and control their drugs not to be released in the human stomach, and target release in the intestines, which not only protects the drugs from being destroyed by gastric acid, but also avoids the stimulation of the drugs on the stomach, so that the drugs can be released in the stomach. The intestinal target releases the effect of absorption.
