Drugs that drop into your NTI group (therapeutic index of two–3 or underneath) often need close checking and dose titration that could not be necessary for non-NTI drugs. A examine done in Norwegian hospitals identified that drug-connected complications have been extra more likely to be connected to NTI drugs versus non-NTI drugs, benefits which were driven by drug interactions, the necessity for increased patient monitoring, and non-ideal dose assignment (Blix et al., 2010).
