Introduction

Antifungal; echinocandin; lipopeptide synthesized from a fermentation product of Aspergillus nidulans.^{1 2 4 5 7}

Uses for Anidulafungin

Candidemia and Other Invasive Candida Infections

Treatment of candidemia and certain other invasive Candida infections (intra-abdominal abscess, peritonitis).^{1 5 8 19 21 24} A drug of choice.^{21 24}

For treatment of candidemia in nonneutropenic patients or for empiric treatment of suspected invasive candidiasis in such patients, IDSA recommends fluconazole or an echinocandin (caspofungin, micafungin, anidulafungin) for initial therapy;²⁴ amphotericin B (conventional or lipid formulation) is the preferred alternative.²⁴ An echinocandin may be preferred for initial treatment in those who have moderately severe to severe candidemia, are allergic to or intolerant of azole antifungals, have recently received an azole, or have or are likely to have infections caused by Candida glabrata or C. krusei.²⁴ Fluconazole may be preferred for initial treatment in those who are less critically ill and have not recently received an azole and for infections caused by C. parapsilosis.²⁴ If an echinocandin is used initially, transition to fluconazole is recommended for patients who are clinically stable and have isolates likely to be susceptible to fluconazole (e.g., C. albicans).²⁴

For treatment of candidemia in neutropenic patients, IDSA recommends an echinocandin (caspofungin, micafungin, anidulafungin) or amphotericin B (a lipid formulation) for initial therapy;²⁴ fluconazole is the preferred alternative in those who are less critically ill or have not recently received an azole;²⁴ voriconazole can be used as an alternative when broader antifungal coverage is required.²⁴ An echinocandin is preferred for C. glabrata infections;²⁴ fluconazole or amphotericin B (a lipid formulation) is preferred for C. parapsilosis infections;²⁴ an echinocandin, amphotericin B (a lipid formulation), or voriconazole is recommended for C. krusei infections.²⁴ For initial empiric treatment of suspected invasive candidiasis in neutropenic patients, amphotericin B (a lipid formulation), caspofungin, or voriconazole is recommended;²⁴ alternatives are fluconazole or itraconazole.²⁴

Safety and efficacy not established for treatment of endocarditis, osteomyelitis, or meningitis caused by Candida.¹

Manufacturer states efficacy data are insufficient to date regarding use of anidulafungin for treatment of candidemia or other invasive Candida infections in neutropenic patients.¹

Esophageal Candidiasis

Treatment of esophageal candidiasis.^{1 3 5 11 21 24 26} A drug of choice.^{21 24}

Esophageal candidiasis requires treatment with a systemic antifungal (not a topical antifungal).^{24 26}

IDSA recommends oral fluconazole as the preferred drug of choice for the treatment of esophageal candidiasis;²⁴ if oral therapy is not tolerated, IV fluconazole, IV amphotericin B (conventional formulation), or an IV echinocandin (caspofungin, micafungin, anidulafungin) is recommended.²⁴ For fluconazole-refractory infections, preferred alternatives are itraconazole oral solution, oral posaconazole, or IV or oral voriconazole;²⁴ other alternatives are an IV echinocandin (caspofungin, micafungin, anidulafungin) or IV amphotericin B (conventional formulation).²⁴

For treatment of esophageal candidiasis in HIV-infected adults and adolescents, CDC, National Institute of Health (NIH), and IDSA recommend IV or oral fluconazole as the preferred drug of choice and itraconazole oral solution as the preferred alternative.²⁶ Other alternatives include an IV echinocandin (caspofungin, micafungin, anidulafungin), oral or IV voriconazole, oral posaconazole, or IV amphotericin B (conventional formulation).²⁶ For refractory esophageal candidiasis, including fluconazole-refractory infections, itraconazole oral solution or oral posaconazole is preferred;²⁶ alternatives include IV amphotericin B (conventional or lipid formulation), an IV echinocandin (caspofungin, micafungin, anidulafungin), or oral or IV voriconazole.²⁶

Patients with frequent or severe recurrences of esophageal candidiasis, including HIV-infected patients, may benefit from long-term suppressive or maintenance therapy (secondary prophylaxis) with oral fluconazole or oral posaconazole; however, the potential for azole resistance should be considered.^{1 3 24 26} Echinocandins not included in recommendations for secondary prophylaxis of esophageal candidiasis.^{24 26} Patients with fluconazole-refractory esophageal candidiasis who responded to an echinocandin should receive voriconazole or posaconazole for secondary prophylaxis until antiretroviral therapy produces immune reconstitution.²⁶

Oropharyngeal Candidiasis

Treatment of oropharyngeal candidiasis†.^{21 24 26} Considered an alternative, not a drug of choice.^{24 26}

IDSA recommends topical clotrimazole or topical nystatin for mild oropharyngeal candidiasis;²⁴ oral fluconazole is recommended for moderate to severe disease.²⁴ For refractory oropharyngeal candidiasis, including fluconazole-refractory infections, itraconazole oral solution, oral posaconazole, or oral voriconazole is recommended.²⁴ An IV echinocandin (caspofungin, micafungin, anidulafungin) or IV amphotericin B (conventional formulation) also are recommended as alternatives for refractory infections.²⁴

For treatment of oropharyngeal candidiasis in HIV-infected adults and adolescents, CDC, NIH, and IDSA recommend oral fluconazole as the preferred drug of choice for initial episodes;²⁶ alternatives for initial episodes include topical clotrimazole or topical nystatin.²⁶ For fluconazole-refractory infections, itraconazole oral solution or oral posaconazole is preferred;²⁶ alternatives include IV amphotericin B (conventional or lipid formulation), an IV echinocandin (caspofungin, micafungin, anidulafungin), or oral or IV voriconazole.²⁶

Patients with frequent or severe recurrences of oropharyngeal candidiasis, including HIV-infected patients, may benefit from long-term suppressive or maintenance therapy (secondary prophylaxis) with oral fluconazole or itraconazole oral solution; however, the potential for azole resistance should be considered.^{24 26} Echinocandins not included in recommendations for secondary prophylaxis of oropharyngeal candidiasis.^{24 26} Patients with fluconazole-refractory oropharyngeal candidiasis who responded to an echinocandin should receive voriconazole or posaconazole for secondary prophylaxis until antiretroviral therapy produces immune reconstitution.²⁶
