| Question | Answer |
|---|---|
| Antifungal drugs | Amphotericin B Caspofungin Fluconazole Flucytosine Itraconazole |

| Amphotericin B pharmacokinetics | Parenteral, NOT CSF, lasts a long time |
| Caspofungin properties | Inhibits beta-glucan synthase, cell can't make a good barrier, exposes it to immune system (headaches, GI distress, histamine release) |
| Caspofungin pharmacokinetics | Parenteral, liver, not really CSF |
| Fluconazole properties | Inhibits ergosterol synthesis |
| Fluconazole pharmacokinetics | Oral, kidney, CSF |
| Flucytosine properties | Forms florouracin in cell, inhibits thymidylate synthetase (rarely bone marrow depression) |
| Flucytosine pharmacokinetics | Oral, kidney, CSF |
| Itraconazole properties | Inhibits ergosterol synthesis |
| Itraconazole pharmacokinetics | Oral, kidney, NOT CSF |
