IOV is usually believed in population PK types although you will find difficulties in precision with superior magnitudes of IOV (Abrantes et al., 2019). Abrantes et al. evaluated 5 approaches to deal with high IOV and concluded that solutions excluding the effects of IOV for individualized dosing were most accurate (however which include IOV estimations for empiric Bayesian estimates was uncovered for being most accurate and specific) (Abrantes et al., 2019). For scenarios through which the IOV is anticipated to be bigger than inter-specific variability, IOV must be excluded from dosing recommendations due to insufficient predictive capacity.
