Which drug is part of the standard induction regimen for cryptococcal meningitis?

• A. Fluconazole
• B. Fluconazole plus flucytosine
• C. Amphotericin B liposomal plus flucytosine
• D. Itraconazole

Answer: (C)

Induction therapy for cryptococcal meningitis aims to rapidly and aggressively clear the fungus from the CSF with drugs that kill Cryptococcus quickly. Amphotericin B liposomal does just that by disrupting fungal cell membranes, producing fast fungicidal activity. When combined with flucytosine, the two drugs work together synergistically, which speeds parasite clearance from the CNS and improves outcomes. The liposomal form is preferred because it reduces nephrotoxicity, allowing a full, effective induction course. Fluconazole, while it penetrates the CNS well, is mainly fungistatic against Cryptococcus and acts too slowly for induction, and itraconazole has poor CNS penetration and isn’t effective for this infection. After induction, fluconazole is typically used for consolidation and maintenance.
