Drugs that has a NTI needs to be dosed more very carefully and also have a more compact drug exposure window amongst poisonous and therapeutic results. These are typically also known as “significant-dose drugs” and infrequently need therapeutic drug checking (TDM) and dose individualization dependant on client-certain traits (Pater, 2004).
