What are external medications?

External medications refer to substances that are applied to the surface of the body rather than ingested or injected. These medications are designed for topical use, which means they work locally where they are applied rather than entering the bloodstream in any significant way. Common forms of external medications include creams, ointments, lotions, and patches used for various conditions such as skin irritations, rashes, or localized pain relief.

The distinction is important in the context of medication administration, as external medications are often used for treating skin conditions directly at the site of application without impacting the body's internal systems significantly. Understanding this concept helps ensure appropriate application and recognizes the boundaries of different types of medication routes and their intended effects on the body.
