What type of medication is administered transdermally?

Transdermal medication involves delivering drugs through the skin using a patch. These patches are designed to release medication at a controlled rate over a specified period, allowing for sustained therapeutic effects without the need for multiple doses throughout the day. This method bypasses the digestive system and can improve patient adherence to medication regimens.

Oral medications are taken by mouth and absorbed through the gastrointestinal tract, injectable medications are delivered via syringe directly into the body, and inhaled medications are administered through the respiratory system. Each of these delivery methods has its specific use cases and advantages but does not encompass the transdermal route. Thus, patches applied to the skin are the correct answer when identifying medications specifically administered through the transdermal method.
