Niosomes are aqueous core enclosed in bilayer consisting of cholesterol and one or more non-ionic surfactants. Niosomes are
having high penetration through the skin compared to liposome and ethosomes. In a vesicular system, the drug- delivery effectively
increases the bioavailability of drug through controlled release of the drug. It provides number of advantages in the drug efficacy,
enhancing patient compliance and comfort. Enhanced delivery of drug through the skin and cellular membranes by means of an
niosomes carrier opens numerous challenges and opportunities for research and future development of novel improved therapies.
This articles deals with the preparation, characteristic / evaluation, applications of niosomes.
