Provide a short flashcard topics of antifungal drugs
| # | Topic | Key Content |
|---|---|---|
| 1 | Drug Classification | 4 classes: Polyenes, Azoles, Allylamines, Others |
| 2 | Polyenes - Mechanism | Bind ergosterol → form pores → cell death |
| 3 | Amphotericin B - PK | IV formulations, t½ = 15 days, liposomal forms |
| 4 | Amphotericin B - Clinical Uses | Systemic Candida, Cryptococcus, Aspergillus, Mucor, Histoplasma, Blastomyces |
| 5 | Amphotericin B - Adverse Effects | Infusion reactions + renal damage (most significant), anemia |
| 6 | Resistance to Amphotericin B | Decreased/modified ergosterol target |
| 7 | Flucytosine (5-FC) | Converted to 5-FU → blocks DNA/RNA synthesis; used with Amph B |
| 8 | Azoles - Mechanism | Inhibit fungal CYP450 → block ergosterol synthesis |
| 9 | Ketoconazole | Oral imidazole; inhibits human steroid synthesis; hepatotoxic; now rarely used |
| 10 | Triazoles Comparison | Itraconazole vs Fluconazole vs Voriconazole |
| 11 | Echinocandins | Caspofungin; inhibit glucan synthesis (cell WALL target); IV only |
| 12 | Griseofulvin | Binds keratin; for Tinea/ringworm; largely replaced by newer drugs |
| 13 | Terbinafine (Lamisil) | Allylamine; inhibits squalene epoxidase; drug of choice for onychomycosis |
| 14 | Topical Antifungals | Nystatin, Miconazole, Clotrimazole, Naftifine, Undecylenic acid, Tolnaftate |
