What is the difference between intramuscular and subcutaneous injections?

What is the difference between intramuscular and subcutaneous injections?

Intramuscular injections are absorbed faster than subcutaneous injections. This is because muscle tissue has a greater blood supply than the tissue just under the skin. Muscle tissue can also hold a larger volume of medication than subcutaneous tissue.

What is the purpose of the subcutaneous injection compared to others?

Subcutaneous injection can be used to give many types of medications for various medical conditions. There are fewer blood vessels in the fatty layer of connective tissue just beneath the skin than the muscle tissue. Having fewer blood vessels means that medication injected subcutaneously is absorbed more slowly.

What is the difference between iv and im injection?

IV drug administration achieves high plasma concentrations rapidly in plasma and tissues. Muscles are very vascular structures, and IM absorption occurs by drug diffusion from interstitial fluid and capillary membranes into plasma, and so onset of action is longer than IV injection.

What are the advantages of subcutaneous injections?

As subcutaneous tissue has few blood vessels, the injected drug is diffused very slowly at a sustained rate of absorption. Therefore, it is highly effective in administering vaccines, growth hormones, and insulin, which require continuous delivery at a low dose rate.

What is a disadvantage of subcutaneous drug administration?

The slower absorption is a common disadvantage of subcutaneous administration because there is less blood flow to quickly absorb drug; however, this may be an advantage as well, in that lower doses of drugs may last for longer periods.

Why are drugs injected into the subcutaneous layer?
