In which injection method is the muscle the primary target for drug delivery?

The intramuscular injection method is characterized by the target of drug delivery being the muscle tissue. When a medication is administered intramuscularly, it is injected directly into a specific muscle group, which allows for faster absorption into the bloodstream due to the rich vascularity of muscle tissue. This route is particularly beneficial for administering larger volumes of medication and for drugs that may irritate subcutaneous tissues if given in that manner.

In contrast, the subcutaneous method involves injecting medication into the fatty tissue just beneath the skin, targeting the subcutaneous layer rather than muscle. Buccal injections involve placing medication between the gums and cheek for absorption through the mucous membranes, while oral administration involves swallowing a medication for gastrointestinal absorption. Each of these methods targets different compartments within the body, making the choice of intramuscular specifically suited for direct muscle delivery, ensuring a prompt therapeutic effect for certain medications.
