What is a suppository?

A suppository is specifically designed as a solid medication that melts or dissolves after being inserted into a body cavity, such as the rectum, vagina, or urethra. This method of administration allows the medication to be absorbed directly into the bloodstream or to act locally, depending on its formulation and intended use.

The key characteristic of a suppository is its ability to maintain a solid form at room temperature, which facilitates easy insertion and stability. Upon insertion, the body temperature causes it to melt or break down, allowing for the therapeutic agents to be released and absorbed effectively.

Other options reflect different forms and methods of medication that do not align with what a suppository represents. For instance, a solid medication that dissolves in water is not applicable to suppositories, as they do not rely on water to release the active ingredient. Additionally, liquid medications are typically taken orally, which is a different route of administration altogether. Medications applied topically involve direct application to the skin, making them distinct from the internal delivery method employed by suppositories.
