Which route delivers medication into the muscle?

• A. Intravenous
• B. Intramuscular
• C. Subcutaneous
• D. Oral

Answer: (B)

When a medication is intended to go into muscle tissue, the route used deposits the drug directly into muscle fibers. That method is intramuscular delivery. An intramuscular injection places the medicine into a muscle (such as the deltoid, vastus lateralis, or ventrogluteal), where it is absorbed through the muscle’s blood vessels into the bloodstream for a systemic effect. This route is different from intravenous, which puts medicine straight into a vein for rapid circulation; subcutaneous, which delivers into the fatty layer under the skin and is absorbed more slowly; and oral, which is swallowed and absorbed through the digestive system rather than into muscle tissue. Therefore, the route that delivers medication into the muscle is intramuscular.
