We call any substance that is used to treat, prevent, and diagnose human diseases, purposefully regulate human physiological functions, and has specified indications or functions, usage, and dosage as a medicine.

Among medicines, we distinguish between injectables and oral medicines.

Are injections really better than taking medicine?

For some diseases, injections are not as effective as taking medicine. For example, oral administration is used for some digestive tract diseases. The local drug concentration in the gastrointestinal tract is high and the treatment effect is good. There is no need for injections for common colds and flu. Even if you take an injection, the effect may not be good. For some drugs that can only be taken orally and not injected, of course, there is no need to suffer the pain and trouble of injections.

Compared with the two routes of administration, oral administration is simpler, easier and safer than injection.

Among medicines, there are oral preparations and injections, but there are very few injections that can be taken orally. The effects of injections and oral medicines are completely different. Injections are unstable in the digestive tract and have strong irritating effects. The solvents are irritating to the gastrointestinal tract, the dosage is difficult to control, and some injections require skin tests.
