    TLDR Certain antiparasitics and antidepressants show promise for treating cryptococcosis, especially when combined with fluconazole.
    This study evaluated the anticryptococcal potential of 27 drugs against Cryptococcus neoformans and Cryptococcus gattii, focusing on their antifungal activity. Antiparasitics such as albendazole, fenbendazole, flubendazole, and mebendazole, along with antidepressants duloxetine and paroxetine, demonstrated significant antifungal activity with a minimum inhibitory concentration (MIC) of 100 µmol L-1 or less. The study found that combining fluconazole with finasteride, hydroxyzine, and paroxetine resulted in additive effects, enhancing fluconazole's ability to kill C. neoformans and suppress fungal growth more effectively. The research highlights the potential of repurposing benzimidazoles and serotonin and norepinephrine reuptake inhibitors for cryptococcosis treatment, with significant improvements observed in fluconazole's efficacy in vitro.

      Ketoconazole 2% shampoo stopped a user's severe hair shedding after just two uses, a result not achieved by finasteride or oral minoxidil. Some users suggest the shampoo's anti-androgenic properties may help with hair loss, while others think the shedding might have stopped naturally or due to the end of a shedding phase.
