Which is faster absorption, subcutaneous injection or intramuscular injection, and why?

Intramuscular injection, referred to as "muscle injection", is the injection of liquid medicine into muscle tissue, which is suitable for the injection of various drugs, such as antibiotics, antipyretics, sedatives, etc. Usually the buttocks with thicker muscles and away from the great nerves and great blood vessels are used, so there is a saying of "spanking needles". It is also more common to hit the deltoid of the upper arm. The difference between it and skin injection is that the injected liquid is more irritating and larger, and larger needles and needles are used (1 ml needle for skin injection and 2-5 ml needle for intramuscular injection). The needle is deeper and the needle tube is perpendicular to the skin surface.

In addition, during intramuscular injection, because the blood vessels contained in the muscle are much richer than those in the skin or subcutaneous, the absorption is rapid, and the drug can quickly reach the body. If a drug that should be dermally injected is injected intramuscularly, a reaction that was originally localized can spread throughout the body. Take vaccine injection as an example. After skin injection, the vaccine can cause normal local reactions, such as redness, swelling, heat, and pain. These reactions can naturally disappear. If intramuscular injection is used, it will turn into abscesses, ulcers, fever, and even On the contrary, not only will the immune effect not be achieved, but individuals with low resistance may also be infected with the diseases that the vaccine is immune to.
