The ADHD patch medication came on the market in 2006, but trans-dermal patches have been around much longer.  While topical applications of medications and substances have been in use since the Babylonians, the first medicinal patch was invented in the early 20th century.  Studies were initially done after several cases of poisoning in children who had touched toxic substances.  It is widely accepted, that the skin, our body’s largest organ, is very capable of absorbing medications.  A large number of medications are safely delivered trans-dermally and are found to be very effective at maintaining constant levels of medication in the blood.There are several medicines that come in patch forms.  Some of the most well-known are nicotine patches.  These patches work by allowing your body to absorb the medication through the skin.  That is called trans-dermal absorption.  Other common medicines that can be absorbed this way are pain medicines.
