We usually have the concept that when you are sick, injections are faster than medicine. In fact, this understanding is not comprehensive enough. The speed of this treatment depends on the specific condition. From the point of view of the speed at which the drug is absorbed to its effect, injections are faster than taking medicines, but not all diseases require injections. For some diseases, injections are not as effective as medicine. For example, some gastrointestinal diseases are administered orally, the local drug concentration in the gastrointestinal tract is high, and the treatment effect is good; for common colds and colds, injections are not necessary. Oral medicine is simpler, easier and safer than injection medicine. Therefore, domestic and foreign medical experts advocate that all diseases that can be treated with medicine should not be injected as much as possible. Both injections and medications are a means of treatment. Which method is best to treat should be chosen by the doctor according to the type of medication, the nature of the disease, and the condition.
