What is the main method of administration for rectal suppositories?

The main method of administration for rectal suppositories is through the rectum. Rectal suppositories are designed to be inserted into the rectal cavity, where they dissolve and are absorbed into the bloodstream or act locally to provide therapeutic effects. This route of administration can be particularly beneficial for individuals who may be unable to take medications orally due to vomiting, difficulty swallowing, or other gastrointestinal issues.

Administering medications via the rectum allows for faster absorption than oral administration in some cases and can provide alternative methods to deliver medications when other routes are not feasible. This method is specifically intended for substances formulated for rectal use, and understanding this route is crucial for safe and effective medication administration.
