Currently, with healthcare changing and improving, oral drug delivery devices have been found to be critical in the improvement of patient management. In the same light, such devices aimed at simplifying the actual administration of the drugs and other prescribed treatments, so that patients can take them as advised. This paper discusses the various categories of oral drug delivery devices with examples, their merits, and their contribution to the level of patient adherence and health outcomes. The first section of our paper will present how some oral drug delivery devices function and their types as well. The range is huge... from the basic pill boxes to the advanced smart pill bottles... This range has specific needs so that patients can adhere to taking the medications, at the right time and in right amounts. With the help of these devices and use of technology, there is effective management of the medication process and administration errors associated with the manual administration of the drugs are significantly eliminated. Our next assignment is going to regard the key merits brought about by the oral drug devices. It would be the increase in patient compliance which is one of the most evident. Reports have indicated that the use of these devices makes the patients committed to their medication and health improving actions. The utilization of these devices helps solve the most common problems affecting patients, which include forgetfulness and confusion about the dosages, by providing easy access and notifications of the drugs. Moreover, most of these devices are enhanced, allowing wider audiences like the elderly and disabled to use them easily. Besides enhancing compliance, oral drug delivery devices facilitate better liaison between health care providers and patients. Patients’ adherence is often hard for health care providers to assess, but many modern devices can be fitted with a remote patient monitoring sensor. Such information is important for altering the regimes and delivering the right service to patients. Such devices enhance the degree of patients and providers’ interaction and therefore help develop confidence as well as promoting discussions on treatment outcomes and side effects. In addition, the progression of personalized medicine has accelerated the creation of oral drug delivery devices too. However, there is an increasing need for drug delivery devices that are able to accommodate varying dosage strengths and formulations, as medicine evolves to more individualised treatments. Such trend not only improves patient adherence to prescribed therapy but also makes sure the patient receives the optimal treatment, with minimizing the risk of side effects, while the expected therapeutic effects are maximized. Finally, we however, need to look at the future of the oral drug delivery devices and of the oral drug delivery systems considering the present technologies that are being employed in the devices. The use of Artificial intelligence, machine learning and other advanced technologies in these devices will automatically take patient care into another level. For example, AI-powered applications could assist in the assessment of patient behaviour and when an anomaly or non-compliance is detected, the machine could suggest possible measures to be taken including treatments. As the history of the healthcare industry has shown, oral drug delivery devices in the future, will be at the very churning centre of patient care advances in the industry. To summarize, the oral drug delivery devices are vital for adherence and health outcome improvement. With the use of these devices, how patients cooperate with their treatment plan is changing as medication management becomes easier, communication improves, and the device meets the needs of different patients. Looking forward, the further development of such devices and their modifications can be anticipated and will lead to new paradigms in patient care and adherence approaches.
