Topical patches are typically designed to deliver the desired substance to a single localized site. Traditional uses include the alleviation of pain and inflammation of specific joints and/or muscles. The primary benefit is derived from the fact that the patch is applied directly to the body area of concern as differentiated from more traditional delivery methods such as pills and capsules.
Benefits of Topical Patches
Through the use of a topical patch, patients:
- Experience a more controlled and sustained delivery (versus a pill)
- Control their own dose, and may choose to remove the patch at their convenience if negative effects are noted
- Bypass the need for multiple dosages throughout the day

What is the difference between a topical and a transdermal patch?
Topical and transdermal patches are physically similar. Both comprise a polymeric adhesive along with other excipients along with the drug/substance intended for delivery. This composition is positioned between a release liner and backing. The difference between a topical and a transdermal patch lies in the mechanism of action. Topical patches are designed with the physical placement of the patch in mind, with an emphasis on localized delivery whereas transdermal patches are designed with the goal of maximizing delivery of the product into the bloodstream. As a result, topical patches are designed to be used to alleviate localized conditions. An example of this is Lidocaine, often used for pain relief solely in the area where the patch is applied.
