ABSTRACT
A transdermal patch is a medicated adhesive patch applied to the skin in order to transdermally administer a
particular dosage of medication into the bloodstream. This frequently encourages the healing of a body part that
has been hurt. A controlled release of the medication into the patient can be achieved using a transdermal patch.
This can occur in one of two ways: either through a porous membrane that covers a reservoir of medication or
through the patient's body heat melting thin layers of medication that are embedded in the adhesive. When
compared to other methods of administering medication, such as orally, topically, intravenously, intramuscularly,
etc., this is an advantage that comes with transdermal drug delivery. Transdermal drug delivery has this advantage
over other methods, including oral, topical, intravenous, intramuscular, etc. Transdermal medication delivery
allows for a constant blood level profile, a regulated drug release into the patient, fewer systemic side effects, and
occasionally higher efficacy than conventional dose forms. The main objective of the transdermal drug delivery
system is to administer drugs into the bloodstream through the skin at a predetermined speed with relatively little
variation from one patient to the next and from one person to themselves.
