Edge Activator

: Transfersomes are bilayer vesicles composed of phospholipid and edge-activators, which are mostly surfactant. Transfersomes based drug delivery system has gained a lot of interest of the pharmaceutical researchers for their ability to improve drug penetration and permeation through the skin. Transdermal drug delivery via transfersomes has the potential to overcome the challenge of low systemic availability. However, this complex vesicular system has different issues to consider for developing a successful transdermal delivery system. One of the major ingredients, phospholipid has versatile sources and variable effect on the vesicle size and drug entrapment in transfersomes. The other one termed as edge-activator or surfactant has some crucial consideration of skin damage and toxicity depending upon its type and concentration. A complex interaction between type and concentration of phospholipid and surfactant was observed, which affect the physicochemical properties of transfersomes. This review focuses on the practical factors related to these two major ingredients such as phospholipid and surfactant. The origin, purity, desired concentration, the susceptibility of degradation, etc. are the important factors for selecting phospholipid. Regarding surfactants, the major aspects are type and desired concentration. A successful development of transfersomes based drug delivery system depends on the proper considerations of these factors and practical aspects.

Osteoporosis is a progressive bone disease that remains unnoticed until a fracture occurs. It is more predominant in the older age population, particularly in females due to reduced estrogen levels and ultimately limited calcium absorption. The cost burden of treating osteoporotic fractures is too high, therefore, primary focus should be treatment at an early stage. Most of the marketed drugs are available as oral delivery dosage forms. The complications, as well as patient non-compliance, limit the use of oral therapy for prolonged drug delivery. Transdermal delivery systems seem to be a promising approach for the delivery of anti-osteoporotic active moieties. One of the confronting barriers is the passage of drugs through the SC layers followed by penetration to deeper dermal layers. The review focuses on how anti-osteoporotic drugs can be molded through different approaches so that they can be exploited for the skin to systemic delivery. Insights into the various challenges in transdermal delivery and how the novel delivery system can be used to overcome these have also been detailed.

Transdermal Route

Background: Hypertension comes under the category of chronic disease, which requires long term treatment. Hypertension is usually treated by oral administration of various therapeutic agents. There are several limitations of the oral route, making pharmaceutical scientists to discover an alternative route for drug delivery. Methods: The transdermal route may be a better alternative as it shows various advantages like lack of first-pass effect and high patient compliance. The skin may act as a primary barrier for the transdermal delivery of anti-hypertensive drugs; therefore, new approaches are required to cross this barrier. Nanocarrier systems come under these new approaches to cross the skin barrier. Various nanocarrier systems explored for transdermal delivery of antihypertensive drugs are liposomes, elastic liposomes, ethosomes, transethosomes, oleic acid vesicles, niosomes, solid lipid nanoparticles, nanostructured lipid carriers, nanoemulsions/microemulsions, and carbon nanotubes. Results: This review summarizes the potential of advanced nanocarrier systems for effective management of hypertension following the transdermal route. The entire literature search regarding the utility of nanocarrier systems in transdermal delivery of antihypertensive drugs was done by using Pubmed and Google Scholar. Conclusion: Nanocarrier systems are capable of reducing various drawbacks of conventional formulations of antihypertensive drugs like excessive first-pass effects, high dosing frequency, and toxicity promoting high patient compliance. However, the clinical efficacy determination of such nanocarrier systems is still a challenge and it will govern their presence in the global pharmaceutical market.
