Which amphotericin B formulation is used in the standard induction therapy for cryptococcal meningitis?

• A. Amphotericin B deoxycholate
• B. Liposomal amphotericin B
• C. Amphotericin B lipid complex
• D. Amphotericin B colloidal dispersion

Answer: (B)

The main idea is that rapid and effective fungal clearance during induction therapy for cryptococcal meningitis is best achieved with a formulation of amphotericin B that combines strong activity with a safer profile. The liposomal formulation fits this well because it delivers the same antifungal potency as other amphotericin B forms but with significantly lower nephrotoxicity and fewer infusion-related reactions. That safer profile allows clinicians to use the full induction dose needed to sterilize the CSF quickly, which is crucial in cryptococcal meningitis. While older formulations like amphotericin B deoxycholate were used in the past, liposomal amphotericin B is preferred when available because it reduces kidney injury and other toxicities without sacrificing efficacy. The other lipid-based or colloidal forms exist, but liposomal amphotericin B remains the standard choice in many guidelines for induction therapy due to its favorable tolerability and safety during the intensive treatment window.
