Benefits of capsules:
1, some drugs have high oil content and are not easy to be made into solid tablets and need to be encapsulated;
2. Some pharmaceutical ingredients are unstable in chemical properties, easy to get wet, or deteriorate under high temperature and light. Making capsules can improve the stability of drugs and prolong the shelf life;
3. Some drugs are insoluble in water, so they are not easily absorbed by the human body in the digestive tract. They must be dissolved in an appropriate oily solvent and then packaged;
4. Some drugs for treating digestive system are only effective when absorbed in the intestine. Because gastric juice is acidic and intestinal juice is alkaline, they must be put into acid-resistant capsule shell, so the drug will only dissolve in alkaline intestine.
