A Review on Targeted Drug Delivery: its Entire Focus on Advanced Therapeutics and Diagnostics

Targeted drug delivery is anadvanced method of delivering drugs to the patients in such a targeted sequences that increases the concentration of delivered drug to the targeted body part of interest only (organs/tissues/ cells) which in turn improves efficacy of treatment by reducing side effects of drug administration. Basically, targeted drug delivery is to assist the drug molecule to reach preferably to the desired site. The inherent advantage of this technique leads to administration of required drug with its reduced dose and reducedits side effect. This inherent advantage of targeted drug delivery system is under high consideration of research and development in clinical and pharmaceutical fields as backbone of therapeutics & diagnostics too. Various drug carrierwhich can be used in this advanced delivery system are soluble polymers, biodegradable microsphere polymers (synthetic and natural), neutrophils, fibroblasts, artificial cells, lipoproteins, liposomes, micelles and immune micelle. The goal of a targeted drug delivery system is to prolong, localize, target and have a protected drug interaction with the diseased tissue.
