Abstract

It has been demonstrated that drug delivery systems can enhance therapeutic efficacy, decrease toxicity, increase patient compliance, and even enable whole new medical treatments. Drug delivery systems are technological processes that shape and preserve drug molecules into forms that are appropriate for administration, such as tablets or liquids. They expedite drug delivery to the precise targeted region in the body, maximising therapeutic effectiveness and reducing buildup of off-target substances in the body. Modern drug delivery systems (DDS) are designed with the aid of cutting-edge technology to accelerate systemic drug delivery to the intended target location, hence increasing therapeutic efficacy and reducing accumulation off-target in the body. As a result, they are crucial to the management and treatment of disease. These (DDS) are multifunctional, biocompatible, biodegradable, and have high viscoelasticity with an extended circulation half-life. They are made of nanomaterials or miniature electronics. This review covers the advanced information regarding Drug Delivery Systems and critical analysis of its importance to enhance drug efficacy.
