Review On: Targeted Drug Delivery System

The goal of a targeted drug delivery system is to deliver medication directly to the site of action. In contrast, conventional drug delivery systems, such as intravascular injections, distribute the medication through systemic circulation. Targeted delivery increases the concentration of the drug in the affected tissue, improving its efficiency while minimizing side effects. One of the key advantages of this technique is the potential for reduced dosage and fewer side effects. The development of targeted drug delivery systems has become a highly preferred and rapidly advancing field in the pharmaceutical industry. Transdermal devices, for example, enable the delivery of drugs across the skin barrier. The primary aim of such systems is to transport the drug specifically to the target site. The main intention of targeted drug delivery is to achieve the desired pharmacological and therapeutic effects by directing the agent to the diseased organ, without harming healthy tissues. This is especially beneficial in cancer treatment using chemotherapeutic agents.
