Niosomes are now widely studied as an
alternative to liposomes, which exhibit certain
disadvantages such as –they are expensive,
their ingredients like phospholipids are
chemically unstable because of their
predisposition to oxidative degradation, they
require special storage and handling and
purity of natural phospholipids is variable.
Niosomes are prepared from uncharged
single-chain surfactant and cholesterol
whereas liposomes are prepared from doublechain
phospholipids (neutral or charged).
Niosomes behave in-vivo like liposomes,
prolonging the circulation of entrapped drug
and altering its organ distribution and
metabolic stability46. Encapsulation of various
anti neoplastic agents in these carrier vesicles
has been shown to decrease drug induced
toxic side effects, while maintaining, or in
some instances, increasing the anti-tumor
efficacy. Such vesicular drug carrier systems
alter the plasma clearance kinetics, tissue
distribution, metabolism and cellular
interaction of the drug46. They can be expected
to target the drug to its desired site of action
and/or to control its release 15.
