Vesicular System-Carrier for Drug Delivery

The application of vesicular system in drug delivery has changed the definitions of diagnosis and treatment in different aspects of biomedical field. The vesicular system as liposomes, niosomes, sphinosomes, transferosomes and pharmacosomes are used to improve the therapeutic index of both existing and new drug molecules by encapsulating an active medicament inside vesicular structure in one such system. It prolong the existence of the drug in systemic circulation and finally reduce the toxicity. Such different systems are widely used in gene delivery, tumor targeting to brain, oral formulations, in stability and permeability problems of drugs. In this review we really focused on different aspects of vesicular system in terms of its advantages, limitation, application and different marketed product of vesicular system as novel drug delivery.
