Targeting the drugs to specific organs and tissues has become one of the critical goals as the use of conventional dosage forms do not help in achieving the desired concentration at the target site during a proper time period [1]. Discovery of new drug delivery systems is one of the growing research areas. The recently discovered new drug delivery systems include lipid, protein and polymer technologies with better lipid distribution in the body, prevention of drug degradation from external environment and reduced rate of drug clearance [2]. This review article is about the latest advancements in drug delivery systems and novel technologies and formations produced to achieve the desired drug delivery [3-5]
