Drug Class: Echinocandin Antifungal

Overview

11 DESCRIPTION ERAXIS for Injection is a sterile, lyophilized product for intravenous (IV) infusion that contains anidulafungin. ERAXIS (anidulafungin) is a semi-synthetic lipopeptide synthesized from a fermentation product of Aspergillus nidulans .

Mechanism of Action

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Anidulafungin is an anti-fungal drug [see Microbiology (12.4) ]. 12.3 Pharmacokinetics General Pharmacokinetic Characteristics The pharmacokinetics of anidulafungin following intravenous (IV) administration of ERAXIS have been characterized in healthy subjects, special populations and patients. Systemic exposures of anidulafungin are dose-proportional and have low inter-subject variability (coefficient of variation 99%) to human plasma proteins. Metabolism Hepatic metabolism of anidulafungin has not been observed. Anidulafungin is not a clinically relevant substrate, inducer, or inhibitor of cytochrome P450 (CYP450) isoenzymes.

Interactions

  • 7 DRUG INTERACTIONS 7.1 Cyclosporine Administration of multiple doses of anidulafungin and cyclosporine to healthy subjects resulted in no significant alteration in the steady state pharmacokinetics of either drug. No dosage adjustment of cyclosporine or anidulafungin is needed when the two drugs are co-administered [see Clinical Pharmacology (12.3) ] . 7.2 Voriconazole Administration of multiple doses of anidulafungin and voriconazole to healthy subjects resulted in no significant alteration in the steady state pharmacokinetics of either drug.
