Transfersomes: the ultra-deformable carrier system for non-invasive delivery of drug. Curr Drug Deliv. 2020 Aug 03;: Authors: Gupta R, Kumar A Abstract Vesicular systems have many advantages like prolong the existence of the drug in the systemic circulation, minimizes the undesirable side-effects, reaches the active moieties to its target sites using the carriers. But the main drawback related to transdermal delivery is to cross stratum corneum which can be overcome by the utilization of novel carrier systems e.g. transfersomes which are ultra-deformable carrier system composed of phospholipid (phosphatidylcholine) and edge activators (surfactants). Edge activators are responsible for the flexibility of the bilayer membranes of transfersomes. Different edge activators utilized for transfersomes include tween, span, bile salts (sodium cholate and sodium deoxycholate) and dipotassium glycyrrhizinate. These activators decrease the interfacial tension therefore increases the deformability of carrier system. Transfersomes can encapsulate both hydrophilic and hydrophobic drugs into a vesicular structure which consists of one or more concentric bilayers. Due to the elastic nature of transfersomes, they can easily cross the natural physiological barriers i.e., skin and deliver the drug to its active site. The main benefit of using transfersomes as a carrier is the delivery of macromolecules through the skin by non-invasive route therefore in...
