Review[Pharma clinics. How I treat...or preventing pain with "patches"].
There exists two distinct types of patches aiming at increasing the pain threshold either systematically or locally. The first type of analgesic patch is a real transdermal delivery system releasing fentanyl. Such potent opioid drug exerts a systemic effect. The other type of patch associates lidocain and prilocain to induce a local anesthesia of the skin without inducing a systemic effect.
