Topical patches are adhesive patches applied directly to the skin to deliver medication. They are designed to release a specific dose of medication over a set period, allowing for consistent absorption into the bloodstream. Commonly used for pain relief, hormone therapy, and smoking cessation, these patches provide a convenient alternative to oral medications. The patches work by using a transdermal delivery system, which allows the active ingredients to penetrate the skin. This method can enhance the effectiveness of the medication while minimizing side effects associated with oral administration. Examples include nicotine patches and fentanyl patches.
