Current Approaches on Transfersomal Patch: A Noninvasive Innovative Booster for Improved Transdermal Drug Delivery.

Abstract

Pharmaceutical research is increasingly focusing on transdermal drug delivery due to its potential for improved compliance and bioavailability. However, it is challenging due to the tight intracellular junctions present in the skin. Researchers have developed noninvasive methods, like transfersomes, to overcome these challenges. Transfersomes are ultra-deformable vesicles utilized for improved transdermal applications. They are made up of a phospholipid-rich lipid bilayer, an edge activator, and an ethanol/aqueous core. After topical treatment, transfersomes can penetrate deeper skin regions, delivering larger concentrations of active compounds. A transfersomal patch is applied to the skin and left for an extended period of time to allow a large dose of medication to permeate into the bloodstream. The transfersomal patch offers an advantage over the transfersomal gel because it allows the transfersomes to be applied under occlusive conditions, resulting in greater permeability, a lower amount of active medication, and a steady supply rather than a massive dose. This review represents the preparation and evaluation of transfersomal patches, recent research approaches, and future aspects of transfersomal patches. This study suggests that drug-loaded transfersomal patches could be a unique option to avoid invasive therapy.
