What does the term "suppository" refer to in medical treatments?

The term "suppository" specifically refers to a dosage form of medication that is designed to be inserted into the rectum. This method allows the medication to be absorbed directly into the bloodstream through the rectal mucosa, providing an alternative when oral administration isn't appropriate, such as in cases of nausea or vomiting. Suppositories can be used for various purposes, including pain relief, bowel regulation, or delivering specific medications that require localized treatment in the lower gastrointestinal tract.

Other options describe different forms of medications. Liquid medication refers to a solution or suspension meant for oral intake, which is administered differently than a suppository. A powder for oral dosing describes substances that are typically ingested by mixing with liquid, while topical creams are applied to the skin. Each of these forms serves different purposes and routes of administration, distinguishing them from the rectal delivery system of a suppository.
