What are they?
Trans-dermal pain patches are a medically adhesive patch that is applied directly onto the skin. Applied topically, the medication in the pain relief patch is released into the bloodstream.
How they work?
As the layers of skin absorb medication from transdermal pain patches (trans meaning through and dermal referring to the dermis (skin), the medication is absorbed via the blood vessels into the bloodstream. From there, the blood carries medication through the circulatory system and through a patient’s body. (ProSolus)
There is a growth for the demand of transdermal pain patches for pain relief due to their lesser side effects than other traditional delivery methods such as oral drugs or intravenous needles.
Because of the way transdermal pain patches are applied topically, the medication bypasses organs in the body that perhaps would otherwise be affected when ingesting oral pills, capsules or liquids.
The key organ is the liver which works in overdrive to absorb oral drugs. Yet, transdermal pain patches method of direct-to-bloodstream delivery bypasses the liver’s metabolic activity.
Transdermal Pain Patches can also assist the medication to bypass the acidic environment found in the digestive system. Oral medication is broken down by acid in the stomach. Sometimes this can be harsh on the human body’s digestive to breakdown. They also bypass the gastrointestinal tract, which may also reduce the risk of side effects.
