How is the nicotine distributed on the patch?

Nicotine patches are designed to deliver a controlled dose of nicotine through the skin. The patch contains a reservoir of nicotine, which is evenly distributed within a polymer matrix or adhesive layer. As the patch adheres to the skin, nicotine is gradually released and absorbed into the bloodstream over a specified period, typically ranging from 16 to 24 hours, depending on the patch's formulation. This method provides a steady supply of nicotine to help reduce withdrawal symptoms and cravings in individuals trying to quit smoking.
