Definition
Noun: A transdermal patch is a small, adhesive, medicated patch that is placed on the skin. It is designed to deliver a specific dose of medication through the skin and into the bloodstream over a controlled, extended period of time.
Usage
A transdermal patch is used as a method of drug delivery. It is applied to clean, dry, and usually hairless skin. The medication is absorbed slowly and steadily, providing a consistent therapeutic effect and often reducing the frequency of doses compared to oral medications.
Examples

- Some forms of hormone replacement therapy are administered via a transdermal patch.
- For patients who have difficulty swallowing pills, a transdermal patch can be an effective alternative.
- It is important to rotate the application site of the transdermal patch to avoid skin irritation.
Advanced Usage
- Transdermal delivery system: This is a more technical term for the technology behind a transdermal patch, referring to the method of administering drugs through the skin for systemic distribution.
- The effectiveness of a transdermal patch depends on factors like the drug's molecular size and the skin's permeability.
