Which option correctly identifies Subcutaneous administration?

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

Answer: (B)

Subcutaneous administration means injecting into the tissue just beneath the skin, specifically the subcutaneous fat. This location has slower, more gradual absorption than muscle or vein, leading to a slower onset and longer duration of effect. It’s used for drugs that don’t require rapid absorption or that benefit from steadier levels, such as insulin or certain anticoagulants. In contrast, intramuscular injections go into muscle and are absorbed faster, intravenous administration delivers the drug directly into the bloodstream for immediate effect, and oral administration involves swallowing a drug that must pass through the digestive system. The option that identifies this route is Subcutaneous.
