What is a suppository?

A suppository is defined as a solid medication designed for insertion into a body cavity, typically the rectum, vagina, or urethra. This formulation allows the medication to dissolve at body temperature, enabling it to be absorbed directly into the bloodstream or to act locally within the cavity where it is inserted. Suppositories are often used for their ease of administration, especially in patients who may have difficulty swallowing pills or where rapid absorption is required.

In contrast, a liquid medication for oral use is taken by mouth and acts differently in the body as it must pass through the digestive system before entering the bloodstream. An injectable form of medication requires a syringe and a needle to administer, delivering the medication directly into the body through muscle, subcutaneously, or intravenously. A topical cream is applied externally to the skin and is intended for localized treatment rather than for systemic absorption through a bodily cavity. Understanding these differences is essential for proper medication administration and patient care.
