Liposomal Drug Delivery System for Cancer Therapy: Advancement and Patents

Background: In this review article, authors reviewed about the liposomes which are amongst various drug delivering systems for the delivery of the therapeutic agents at the target site. Methods: Advances in liposomal drug delivery systems for the cancer therapy have enhanced the therapeutic levels of the anticancer moieties. Liposomes show promising action on the tumor by incorporating less amount of drug at the target site, with minimum toxic effect and maximum therapeutic effect and thereby enhancing the bioavailability. Results: Liposome-based drug delivery systems provide the potential to elevate the effect of drug concentration in tumor cells. Manuscript briefly describes the role of liposomes in cancer therapy and various patents based on the same.
