ABSTRACT

Human civilizations have used chemicals as cosmetic and therapeutic agents on the skin for thousands of years. The use of the skin as a medicine delivery method did not begin until the 20th century, though. A transdermal patch is an adhesive patch applied to the skin that contains medication that is intended to be transdermally absorbed into the bloodstream. This frequently encourages the healing of a body part that has been hurt. Transdermal drug delivery has an advantage over other drug delivery methods, such as oral, topical, intravenous, intramuscular, etc. Therapeutic agent application topically has several benefits over traditional oral and invasive medication delivery strategies. Further offering a prolonged period of regulated medication release. The preparation procedures for various transdermal patch types, including membrane matrix, drug-in-adhesive, and micro reservoir patches, are covered in this review article. The various transdermal dosage form evaluation techniques have also been studied.
