Abstract

Caspofungin, micafungin and anidulafungin are antifungal drugs with excellent safety profiles. Dosing regimens and treatment durations must be appropriate for optimal patient outcomes. Overall, factors that affect dosing of all three drugs are similar. Drug-specific properties, including in vitro concentration-dependent antifungal activity, activity against fungal biofilms, and pharmacokinetic and pharmacodynamic parameters influence dose selection and duration of therapy. Dosing strategies that provide unbound plasma drug concentrations exceeding the minimum inhibitory concentration (or minimum effective concentration) of the fungus are essential. Patient weight, age and illness severity are also important considerations for adequate exposure to drug: individuals >66 kg, pediatric patients and the critically-ill clear drug at higher rates although drug product information guidelines do not recommend for these populations to receive doses higher than those currently used. Clinical studies of treatment of, and prophylaxis against, Candida and Aspergillus infection indicate that currently recommended dosing regimens are adequate in most instances.
