Exploring digital therapeutics: The next paradigm of modern health-care industry

In this era of 21(st) century, the most valuable resource is data. Digital technology can generate terabytes of data which has a tremendous potential in the modern-day world. Pharmaceuticals play an essential role in improving and maintaining the health of patients. However, their cost in health-care budget is a major issue. Due to high prevalence and unfavorable consequences, managing chronic and lifestyle disorders has now become areas of major clinical concern globally. Harnessing this digital technology in our overburdened health-care industry can improve the treatment outcome and even replace the existing treatment. Health authorities such as U.S. Food and Drug Administration (USFDA) are also acknowledging their potential. FDA's Center for Devices and Radiological Health has established the “Digital Health Program” which seeks to promote public health and provide continued regulatory clarity by enhancing outreach to digital health customers and developing and implementing regulatory strategies and policies for digital health technologies. The main focus of this article is to give an overview of digital therapeutics (DT), its clinical applications, role of regulators, and challenges ahead along with potential areas for developers and to present an update on major developments and initiatives taken in this field. The most important advantages of DT are that it has direct access to patients, decreases cost of treatment, encourages healthy lifestyle modifications, and can substitute or complement conventional treatments. Many of these models are still in infancy stage, and further research and development is needed to demonstrate their enormous potential in near future. If used judiciously, they can modernize our health-care industry.
