What term describes drugs applied to the skin or mucous membranes?

Topical drugs are specifically formulated to be applied to the skin or mucous membranes. These drugs are designed to deliver their therapeutic effects locally where applied, often used in forms such as creams, ointments, gels, or patches. This method allows for direct treatment of skin conditions or localized issues without systemic absorption, although some topical medications can be absorbed into the bloodstream.

Inhalable drugs refer to those that are administered through the respiratory system, typically targeting conditions affecting the lungs and airways. Oral drugs are taken by mouth and absorbed through the gastrointestinal tract, while injectable drugs are administered via a syringe, entering the body through various routes such as intramuscularly or intravenously, often for systemic effects.

Understanding these terms is essential for administering medications properly and knowing their routes of administration and intended effects.
