Transdermal Drug Delivery System – A Review

A transdermal patch is an adhesive patch which carries medicine and is placed on the skin to deliver drug to the bloodstream transdermally. This generally encourages recovery of an injured body part of your body. A transdermal patch facilitates for a controlled release of the drug into the patient, often by the body's heat melting thin layers of the medication incorporated in the adhesive or through a porous membrane concealing a depot of medication. Transdermal drug delivery has this benefit over other drug delivery methods, such as intramuscular, intravenous, topical, oral, etc. Transdermal medication delivery allows for a constant blood level profile, a regulated drug release into the patient and fewer systemic side effects.
