Rise of implantable drugs: A chronicle of breakthroughs in drug delivery systems

In recent years, implantable drug delivery systems (IDDSs) have undergone significant advancements because they offer many advantages to patients and health care professionals. Miniaturization has reduced the size of these devices, making them less invasive and easier to implant. Remote control provides more precise medication delivery and dosage. Biodegradable implants are an additional advancement in implantable drug delivery systems that eliminate the need for surgical removal. Smart implants can monitor a patient’s condition and adjust their drug doses. Long-acting implants also provide sustained drug delivery for months or even years, eliminating the need for regular medication dosing, and wireless power and data transmission technology enables the use of devices that are more comfortable and less invasive. These innovations have enhanced patient outcomes by enabling more precise administration, sustained drug delivery, and improved health care monitoring. With continued research and development, it is anticipated that IDDSs will become more effective and provide patients with improved health outcomes. This review categorizes and discusses the benefits and limitations of recent novel IDDSs for their potential therapeutic use.
