Abstract
If the therapeutic agent can be introduced into the patient’s body at the optimal time and in the optimal dose, or if the optimal concentration can be maintained by doing so, it should be possible to provide a higher quality of care than is currently available. One strategy is to monitor the patient’s condition and the concentrations of therapeutic agents in the body, and then to estimate the timing and dosage of medication. This paper describes the research and development of digital technology-based biomarkers and digital biomarkers for several diseases and conditions （diabetes, Parkinson’s disease, asthma, COPD, pain, itch, hypertension） that are being implemented to optimize treatment.
