Which term denotes a medication that is administered through the rectal route?

The term that denotes a medication administered through the rectal route is "Rectal." This route of administration is specifically designed for delivering medications directly into the rectum, where they can be absorbed into the bloodstream or act locally. Medications given by this route can be beneficial for patients who are vomiting, unconscious, or unable to take medications by mouth. The rectal route allows for various forms of medication, including suppositories and enemas, enabling effective treatment when other routes may be compromised.

The other terms provide alternative routes of administration: "Otic" refers to medications administered into the ear, "Oral" refers to those taken by mouth, and "Sublingual" indicates medications placed under the tongue for rapid absorption. Each of these routes serves specific therapeutic purposes distinct from the rectal route.
