Antifungal Flashcards
How do fungi differ from bacteria
Eukaryotes
80S ribsomes compared to 70S
Slow growing
Rigid cell wall
Griseofulvin mechanism
Mitotic inhibitor
5 Flucytosine use
W/ Amphotericin B to treate Cryptococcal meningitis
5 flucytosine mechanism
DNA/RNA synthesis inhibitor
Ampho B can be use with
5-FC for Cryptococcal meningitis
Triazoles for synergism/additivity
Ampho B drug delivery mechanisms
Fungizone (Better dissolution)
Liposomal (Increase conc., Dec. time, Dec toxicity)
Sterol complex (decrease necrosis)
Flucytosine vs Ampho B Absorption Solubility Spectrom Toxic Resistance
Oral vs IV Soluble vs Not soluble Narrow spectrum vs wide Bone marrow depression vs Nephrotoxic Resistance vs non
Specificity of Imidazoles vs Triazoles
Triazoles are more specific
Imidazoles
Ketoconazole
Clotrimazole
Miconazole
Fluconazole use
Oropharyngeal/vaginal candidiasis
Capsofungin mechanism
Inhibition of Beta-1,3 gluan synthase leading to osmotic lysis
Tavaborole mechanism
Inhibits Leucyl tRNA synthetase
