Transdermal patches—medicated adhesive pads placed on the skin that release drugs gradually for up to a week—have been available in the U.S. for more than 20 years. The first transdermal patch, approved by the U.S. Food and Drug Administration in 1979, delivered scopolamine to treat motion sickness. Since then, more than 35 transdermal patch products have been approved. Examples include the nicotine patch that helps people quit smoking, the lidocaine patch for relieving pain, and a patch containing hormone derivatives for preventing pregnancy.
