What term describes treatment introduced into the body other than orally?

• A. Parenteral
• B. Topical
• C. Intradermal
• D. Transdermal

Answer: (A)

The correct term that describes treatment introduced into the body other than orally is "parenteral." This term specifically refers to any route of administration that bypasses the gastrointestinal tract, which includes methods such as intramuscular injections, intravenous infusions, and subcutaneous injections. Parenteral administration allows for quicker absorption and action of the medication compared to oral routes, making it a preferred method for certain medications and treatments.

Topical refers to medications applied directly to a localized area of the skin or mucous membranes, typically for localized effects rather than systemic absorption. Intradermal refers specifically to injections made into the dermis layer of the skin, and while it is a form of parenteral administration, it is narrower in scope. Transdermal refers to the delivery of medication through the skin, usually via patches, for systemic effects; however, it is a specific method under the broader category of parenteral routes.
