If you have wondered what goes inside a pain relief patch, this guide is for you. As a manufacturer with over three decades of experience, we know: the ingredients matter.

Section 1: Understanding Transdermal Drug Delivery

What Makes Skin Absorption Possible?

Your skin absorbs certain substances. Transdermal patches deliver medications directly through the skin, offering controlled release, higher bioavailability, fewer side effects.

The Three-Layer Structure

Most quality patches have: backing layer (protection), drug reservoir (active compounds), and release liner (protects before use).

Section 2: The Four Main Categories

Category 1: Analgesics

Lidocaine: Numbs pain by blocking nerve signals. 4-5% in OTC patches.
