What is the injection?

The injection is a way of administering a liquid medication into the body tissues under the skin, which usually use a sterile, sharp and hollow needle tube, that is, injection needle. Injection is generally used for drugs which need to have quick effect or which are not absorbed well in the body’s digestive system.
