Cards

Term
Griseofulvin MOA
Definition
disrupts mitotic spindle causing mitotic arrest in fungal cells
Term
Griseofulvin ADE
Definition
CATS-leukopenia, anemia, inc hepatic enzymes, neurotoxicosis, teratogenic
Term
Amphotericin B. MOA
Definition
Binds ergosterol in fungal cell membrane and makes it more permeable so the cell goodies leak out=cell death
Term
Amphotericin B. ADE
Definition
Dose dependent nephrotoxicity***ie:inc BUN/CREA
Plebitis, fever, v/d
Term
Nystatin MOA
Definition
Binds ergosterol in fungal cell membrane and makes it more permeable so the cell goodies leak out=cell death
Term
Nystatin ADE
Definition
High doses=GI upset
Term
Nystatin Spectrum
Definition
Candida. Oral and topical** antifungal but is not absorbed orally
Term
Triazoles, list drugs
Definition

Voriconazole

Fluconazole

Itraconazole

Posaconazole

 

"V-FIP"

Term
Imidazole, list drugs
Definition

Miconazole

Eniloconazole

Clotrimazole

Ketoconazole

"MECK"

Term
Diff bt Triazoles and Imidazoles
Definition
Triazoles=less effect on mammal sterol synthesis, longer elimination Imidazoles=More endocrine adverse effects, affects mammal sterol synthesis
Term
Azole drug MOA
Definition
inhibit ergosterol synthesis in the fungal cell membrane by inhibition of P450-dependent enzyme
Term
Ketoconazole ADE
Definition
Most commonly-GI effects
Elevated liver enzymes/hepatotoxicity**
Teratogenic
also inhibits mammalian p450 enzymes
Term
Fluconazole ADE
Definition
GI>CNS>skin
mild hepatic enzyme elevations
Term
Iatroconazole ADE
Definition
Elevated liver enzymes/hepatotoxicity
but better for long term than ketoconazole
Term
Voriconazole ADE
Definition
unknown, but liver enlgment seen in one study in dogs
Term
Terbinafine MOA
Definition
Inhibits squalene epoxidase to decrease synthesis of ergosterol in fungal cell membranes
Term
Terbinafine ADE
Definition
Facial dermatitis in cats
elevated liver enzymes in dogs
Term
Lufenuron MOA
Definition
chitin synthesis inhibitor
Term
Flucytosine MOA
Definition
Converted to active 5-FU and incorporated into RNA=disrupts protein synthesis, or inhibits DNA synthesis
Term
Fluocytosine ADE
Definition
anemia, leukopenia, thrombocytopenia if 5-FU conversion occurs in GIT
Term
Iodides MOA
Definition
inhibit fungal growth (per Fajt) stimulates host immune response or inc elimation of fungi through skin or hair (per red book)
Term
Topical antifungals
Definition
Enilconazole, clotrimazole, miconazole, natamycin, nystatin
Term
Natamycin MOA
Definition
Binds ergosterol in fungal cell membrane and makes it more permeable so that the cell goodies leak out=cell death
Term
Natamycin ADE
Definition
toxic systemically
Term
Acyclovir
Definition
tx herpes
Term
Amantadine
Definition
tx influenza virus
also NMDA antagonist so may be effective adjunct analgesic
Term
Cytarabine
Definition
antiviral
parenteral antineoplastic for dogs and cats
Term

Definition
ie:tamiflu
TX-influenza
banned in poultry
Term
Idoxuridine
Definition
herpes virus in cat eyes
Term
Zidovudine
Definition
FIV, FeLV
Term
Major protozoal pathogens in veterinary medicine
Definition
Eimeria, isospora, toxoplasma, leishmania, tritrichomonas, sarcocystis, babesia
Term
