Liposomes for Advanced Drug Delivery

Liposomes are sphere-shaped vesicles consisting of one or more phospholipid bilayers. The liposomal drug delivery systems were utilized for delivery of compounds for different diseases. These systems improve the stability as well as cellular uptake of drugs. Site-specific delivery to the target site reduced the site effects. This chapter summarizes the recent advances in liposomal drug delivery systems (i) therapeutic applications-based chemotherapy; (ii) chemotherapy in combination to gene therapy and immunotherapy; (iii) theranostic applications for precise detection and simultaneous treatment of critical diseases and heavy metal toxicity; (iv) stimuli-triggered liposomes. This chapter gives a detailed account on aforementioned applications which might be beneficial to pharmaceutical scientists and industries to develop safe and effective liposomal systems.
