Targeted drug delivery, additionally referred to as good drug delivery, could be a methodology of treatment that involves the increase in medicinal drug in one or few body elements as compared to others. Two strategies are widely used for drug targeting to the specified organ/tissue: passive targeting and active targeting. Drug delivery vehicles transport the drug either at intervals or within the locality of target. An ideal drug delivery vehicle is meant to cross even stubborn sites like a blood brain barrier. Recently, nano medicine has emerged because the medical application of nanotechnology. Since nanoparticles are very tiny in size, nano drug delivery can allow for the delivery of drugs with poor solubility in water and additionally aid in avoiding the primary pass metabolism of liver. Nanotechnology derived drug delivery will cause the drug to stay in blood circulation for a protracted time, thereby resulting in lesser fluctuations in plasma levels and so, token facet effects. These include polymer-drug conjugates and nano particulate systems such as liposome�s, quantum dots, dendrimers, etc. There are several other approaches as well. These also include the strategies wherein the therapeutic agents are coupled with �targeting ligands� that possess the ability to recognize antigens associated with tumors.
