Individualized dosing regimens specific to the patient, infection, bacteria, and antibiotic can optimize outcome. Integration of pharmacokinetic and pharmacodynamic data, called dual individualization, can be accomplished through the use of AUIe. AUIC dosing has been shown to predict bacteriological outcomes, hasten clinical outcomes, reduce the emergence of resistance, and be cost-effective. MPC dosing has been shown to predict the emergence of resistant submutants. AUIC and MPC information can provide guidance as to when low doses can be used, and when higher concentrations are required. This strategy can ensure efficacy, minimize toxicity, reduce the opportunity for resistance to occur, and save money. REFERENCES I. Paladino JA.
