For drugs whose therapeutic index falls involving three and 10, the utility of precision dosing is less distinct, but there is however sizeable chance click here for profit. To determine suitability of precision dosing in these drugs, it is particularly vital that factors aside from therapeutic index by yourself are considered.
Precision dosing is probably going not needed for drugs by using a therapeutic index above ten (Unless of course big Price tag personal savings could be obtained as a result of additional productive usage of a drug product) but could significantly profit drugs with narrow therapeutic indices.
