Drug delivery systems is a multidisciplinary research field and technological approach focused on developing methods and formulations for introducing therapeutic agents into or through the body to achieve a desired pharmacological effect. This field investigates strategies to control the rate, time, and location of drug release, employing specialized carriers, devices, or formulations to optimize pharmacokinetics, improve therapeutic index, and enhance targeted delivery. Its significance lies in improving therapeutic efficacy, reducing adverse effects, and enabling the clinical application of diverse pharmaceutical compounds.
