Which method of medication delivery involves placing the drug under the skin?

• A. Intramuscular injection
• B. Subcutaneous implant
• C. Oral medication
• D. Transdermal patch

Answer: (B)

The method of medication delivery that involves placing the drug under the skin is through a subcutaneous implant. This delivery system allows for the introduction of medications directly into the subcutaneous tissue, which is the layer of fat and connective tissue located beneath the skin.

Subcutaneous implants provide a sustained release of medication over time, ensuring consistent therapeutic levels with less frequent dosing compared to other methods. This makes them particularly beneficial for conditions that require long-term treatment, such as hormonal therapies or contraceptives.

In contrast, intramuscular injections introduce medication into the muscle, which is a different anatomical site and often has a faster absorption rate. Oral medications are taken by mouth and absorbed through the gastrointestinal tract, while transdermal patches deliver medication through the skin but do not involve subcutaneous placement. Each method has its own specific applications and benefits, but for subcutaneous delivery, implants are the appropriate choice.
