What is the parenteral route defined as?

By swallowing the drug By inhaling the drug By topical application By injecting the drug

Correct Answer:

By injecting the drug

Explanation:

Parenteral administration means delivering a drug by injection, bypassing the gastrointestinal tract. This includes intravenous, intramuscular, and subcutaneous routes, and can also encompass other injected methods. Because the drug goes directly into the tissues or bloodstream, it often gives a rapid or more controlled onset and is used for medications that are poorly absorbed orally or degraded in the GI tract. The other options involve swallowing (oral/enteral), inhaling (inhalation), or applying to the skin (topical), which do not fit the parenteral definition.
