Precision dosing is probably going not needed for drugs having a therapeutic index more than 10 (unless big Charge savings can be reached as a result of additional efficient usage of a drug product or service) but may significantly advantage drugs with slim therapeutic indices. Drugs that tumble in to the NTI classification (therapeutic index of 2–3 or under) typically have to have shut checking and dose titration that might not be needed for non-NTI drugs.

The exact impact of the drug on somebody will depend on the dynamic relation amongst quite a few variables, specially the extent of tolerance, the dose anticipated with the organism and the actual drug dose. Simulations using a previously published mathematical product of drug tolerance reveal the influence of the dose scaled-down than the dose the organism has designed tolerance to is tough to predict and should be opposite on the action of the standard dose.
