Glycerosomes: Novel Nano-Vesicles for Efficient Delivery of Therapeutics.

BACKGROUND

The topical drug delivery system has gained more attention in recent years as compared to oral and parenteral drug delivery. However, owing to the barrier function of the skin's topmost layer, only a few drug molecules can be administered by this route. Therefore, encapsulating the drugs in glycerosomes is one potential solution to this problem. Glycerosomes are vesicular drug delivery systems primarily made up of large concentrations of glycerol, phospholipid, water, and other active ingredients.

OBJECTIVE

The main aim of this review is to summarize the most recent information on the encapsulated vesicular system used in cosmetic preparations, specifically glycerosomes made from both synthetic and naturally occurring plant bioactive substances.

PURPOSE: Glycerosomes offer many benefits, including increased efficacy, better stability, improve absorption, drug targeting at specific sites, and delivering the same at a predetermined rate.

METHOD: The mechanism behind the penetration of glycerosomes is the hydration and lipid fluidization of skin, fabricated by glycerol.

RESULT: Numerous methods have been reported for the formulation of glycerosomes, including the thin film hydration method, reverse-phase evaporation, solvent spherule, detergent removal method, and so on.

CONCLUSION

Researchers are currently investigating the potential of glycerosomes as nanocarriers for natural bioactive and synthetic drugs. This review describes the structure of glycerosomes, preparation techniques, applications, distinctions from liposomes, and benefits of glycerosomes.
