What are the advantages and disadvantages of controlled drug release systems?5 answersControlled drug release systems offer several advantages over conventional drug delivery methods. These systems can enhance treatment efficacy and improve patient compliance by maintaining consistent drug concentrations in the blood, optimizing therapeutic effects, and reducing side effects. They also provide sustained release of drugs, allowing for less frequent dosing and better dosing patterns. Additionally, controlled drug release systems can protect therapeutic proteins and peptides against degradation, ensuring their effectiveness. However, these systems may face challenges such as changes in drug performance due to physiological factors like patient age or food intake. Furthermore, the development of controlled drug delivery systems requires careful design considerations and may involve complex techniques. Safety concerns and limitations in triggering mechanisms have also hindered the translation of some techniques from in vitro to in vivo applications.
