What type of medication may be administered through the skin?

Topical medication is specifically designed to be applied directly to the skin. This method allows for localized treatment of skin conditions such as rashes, infections, or inflammation. Topical medications can include creams, ointments, lotions, and gels that deliver the active ingredients directly to the site of application, facilitating effective relief for the affected area without the need for the medication to enter the bloodstream extensively.

In contrast, oral medication is taken by mouth and absorbed through the digestive system, while parenteral medication refers to medications administered by injection, bypassing the digestive tract entirely. Sublingual medication is placed under the tongue for quick absorption into the bloodstream, also not associated with skin application. Therefore, topical medication is the correct answer as it pertains directly to administration through the skin.
