Drugs with a large therapeutic index (exceeding a worth of ten) may be dosed for most people without the need of leading to adverse occasions or therapeutic failure (Tamargo et al., 2015). Drugs by using a NTI have to be dosed a lot more diligently and possess a smaller drug publicity window concerning harmful and therapeutic consequences. They are also called “significant-dose drugs” and sometimes require therapeutic drug monitoring (TDM) and dose individualization according to patient-distinct attributes (Pater, 2004).
