Specialized drug delivery systems are of much importance in modern medicine as it targets the specific sites or organs, therefore it enhances the efficacy and reduces adverse effects. Multiple strategies and techniques such as nanoparticles, liposomes, micelles, hydrogels, fast dissolving tablets, prodrugs, and drug-loaded erythrocytes are used in designing and advancing specialized drug delivery systems. These systems offer significant benefit in the field of personalized therapies among various diseases, ranging from inflammatory diseases to cancer, through precise control over pharmacokinetics and targeting techniques. There is need to understand the principles of specialized drug delivery which helps to utilize various pharmaceuticals in improving patient quality of life and outcomes.
