In Cancer therapy, Nano drug delivery system comprising of Liposomes, are the most successful mode of treatment in present scenario which also has real time clinical application. Recently it is found that the closed bilayer phospholipid vesicles have many technical advantages over the initially used liposomal formulations. The delivery of therapeutics encapsulated in liposomes changes the biological distribution profile and improves the drug therapeutic indices of various drugs. This review article throws light onto many clinical liposomal drug delivery products. The liposome Nano drug delivery by the active and passive targeting is a boon as it can reduce the off-targeting effects. The current development is more focused on the diagnostic and clinical applications. Receptor targeted delivery systems are extensively explored for active targeting. However, these delivery systems are rarely seen in the clinical application because of conjugation chemistry and other implicit hurdles to develop this system.The development of nanocarriers in the cancer treatment have enormous potential in the medical field. Moreover, Immuno liposomes have been used in cancer treatment as attractive drug targeting vehicles. On the other hand, there are many other liposomal drug delivery systems having passive targeting mechanism for cancer treatment which are widely used due to enhanced retention and permeability of formulation. This review majorly focuses on the current challenges encountered in development of liposomal Nano drug delivery systems and its effective development for cancer treatment.
