Condition condition is among The main factors to take into consideration when identifying if a drug should be prioritized read more for precision dosing. The integration of precision dosing is likely for being most practical in areas of large unmet professional medical want (Darwich et al., 2017), which include things like infectious disease, hematology, immunology/transplantation, oncology, neurology, together with other therapeutic spots observed by Scavone and colleagues (Scavone et al., 2019). Sickness connected morbidity, mortality, and progression is usually quite variable and will enormously effects the need for drug dosing individualization. If precision dosing were to lead to substantial mortality reductions for a sickness/drug blend, that on your own would most likely outweigh any factors that indicated that a drug would or else not be a good applicant for precise dosing.
