Recent Advances in Drug Delivery
Simplicity of drug administration, safety, affordability and effectiveness are the most important issues in pharmacotherapy resulting in exploration of higher drug delivery systems. Drug targeting to specific organs and tissues has become one in all the essential endeavors of the century since the utilization of drugs in standard dosage forms typically involves difficulties in achieving the target site at the acceptable dose during or after a definite time. Consequently, the look for new drug delivery approaches and new modes of action represent one of the frontier research areas. New drug delivery systems incorporate lipidic, proteic and polymeric technologies to produce new sustained drug delivery with higher body distribution, drug protection from harsh external surroundings and avoidance of drug clearance. several of these technologies have reached the market thus proving the advantages of those new carriers.
