Drug targeting is a research area focused on the development of drug delivery systems that can specifically target and deliver therapeutic agents to the diseased tissue or cells, while minimizing systemic exposure and off-target effects. This approach aims to increase the efficacy of drugs, reduce side effects, and improve patient outcomes. Various targeting strategies, such as ligand-receptor interactions, antibodies, nanoparticles, and liposomes, are utilized in drug targeting research to achieve precise delivery of drugs to the desired site of action.
