The therapeutic index depends upon a variety of drug-precise factors and describes the ratio concerning a drug’s most tolerated dose and cheapest efficient dose (Levy, 1998). Drugs with a large therapeutic index (exceeding a worth of 10) can be dosed in many sufferers without creating adverse activities or therapeutic failure (Tamargo et al., 2015).
