How is medication delivered via intramuscular administration?

Intramuscular administration involves delivering medication directly into a muscle, which allows for faster absorption compared to subcutaneous administration. The technique typically involves using a syringe to inject the medication into a large muscle mass, such as the deltoid or gluteus maximus. This route provides a more substantial volume of medication than subcutaneous injection and is often used for vaccines and certain medications that require rapid systemic distribution. The muscular tissues have a rich blood supply, which facilitates quicker onset of action for the medication being delivered.
