Which route is used for delivering medication into muscle tissue?

• A. Intravenous
• B. Intramuscular
• C. Intranasal
• D. Sublingual

Answer: (B)

The route that places medication into muscle tissue is intramuscular. Muscle tissue has a rich blood supply, so drugs delivered into the muscle are absorbed into the bloodstream relatively quickly, giving a predictable and faster onset than some other routes while avoiding the digestive tract and first-pass metabolism. This makes intramuscular administration a preferred option for meds that need quicker effect than oral routes but don’t require direct IV delivery. In contrast, intravenous administration goes straight into a vein for the fastest possible onset, intranasal delivers across the nasal mucosa, and sublingual is absorbed under the tongue; none of these target muscle tissue.
