Abstract
Niosomes are widely used nowadays as a novel drug delivery system. The
amphiphilic nature of the niosomal drug delivery system provides an added advantage
for a large number of newly discovered drugs. In this context, the bilayered structure of
the niosomes helps in modifying various parameters involved in drug encapsulation. The
niosomal drug delivery system also helps in altering the bioavailability, enhancing the
skin permeability, and improving the drug interaction at the targeted sites. The present
chapter focuses on the factors that influence niosomes formation, advantages and
disadvantages of niosomal drug delivery systems, the formulation of niosomes in herbal
products, their future prospects, commercial benefits as well as availability.
