Fundamentals of Targeted Drug Delivery

The goal of targeted drug delivery systems (TDDS) is to identify the target and deliver the loaded bioactive into predefined target with minimum unhealthy side effects. Drug targeting makes it simpler for the medicinal agents to achieve the desired boy site and demonstrates an enhanced beneficial effect at a predefined rate and time. Additionally, it improved the pharmacological effect and reduced unpleasant taste of drug. The role of TDDS is to identify the drug part precisely into its affected body area to overcome a particularly lethal impact of traditional drug delivery, thus decreasing the quantity of drug needed for therapeutic effectiveness. The benefits of the TDDS are the decrease in the occurrence of the dosing, consistent drug effects, decrease of drug side effects, and minimization of the variation in distributing drug quantities. Various carrier systems include colloidal delivery systems, cellular systems, and polymeric systems. This chapter discusses the basic principles of TDDS, types of TDDS, commonly used drug delivery systems, and future prospects of TDDS.
