Drug Delivery Systems (DDS) (159)

A drug delivery system is a technical framework designed to precisely control the spatial, temporal, and dosage distribution of drugs within the body. It enhances patient health by optimizing the delivery of therapeutic agents to their intended targets while minimizing off-target accumulation. Unlike traditional drug delivery methods such as oral tablets, capsules, intravenous injections, inhalation preparations, and transdermal patches, advanced drug delivery systems employ innovative technologies with high technical thresholds. These include delivery mechanisms based on liposomes, nanoparticles, microspheres, exosomes, engineered AAV vectors, 3D-printed drug formulations, and more. Such systems enhance drug efficacy and reduce toxic side effects by targeting specific release sites, modifying the metabolic behavior of drugs, improving sustained and controlled release properties, and enabling penetration through physiological barriers like the blood-brain barrier.
