Mycobacterium Drugs (Nagle)

Mycobacterium Drugs (Nagle)

  • clarithromycin, azithromycin, rifabutin

    What are the 1st line treatments for MAC? (3)

  • prevent action of hydrophobic abs, allow cell to dehydrate w/out dying, allow cell to grow in macrophages and hide from immune system

    What are the functions of mycolic acid? (3)

  • inhibits the function of AcpM acyl carrier protein; prevents biosynthesis of mycolic acids needed for cell walls

    Isoniazid MOA?

  • vitamin B6/pyridoxine; reduce risk of peripheral neuropathy

    What must be given with Isoniazid?

    Why?

  • inhibits mycolic acid biosynthesis by inhibiting mycobacterial fatty acid synthase

    Pyrazinamide MOA?

  • -inhibits arabinosyl transferases; preventing cell wall synthesis

    Ethambutol MOA?

  • a

    High doses of this drug can cause optic neuritis.

    a) ethambutol

    b) isoniazid

    c) pyrazinamide

    d)aminosalicylic acid

  • c

    Which one is a protonophore?

    a) ethambutol

    b) isoniazid

    c) pyrazinamide

    d)aminosalicylic acid

  • d

    Which one has extremely high rates of GI irritation?

    a) ethambutol

    b) isoniazid

    c) pyrazinamide

    d)aminosalicylic acid

  • Aminosalicylic Acid

    - PABA analog- inhibits folate enzymes

  • e

    Which has a similar MOA to Isoniazid?

    a) Capreomycin

    b) Clofazimine

    c) Bedaquiline

    d) Pretomanid

    e) Ethionamide

  • a

    Which has a similar MOA to Aminoglycosides?

    a) Capreomycin

    b) Clofazimine

    c) Bedaquiline

    d) Pretomanid

    e) Ethionamide

  • nephrotoxicity, ototoxicity, eosinophilia

    AEs of Capreomycin? (3)

  • Clofazimine

    -binds to guanine bases of DNA & inhibits template function

    - increases phospholipase A2 activity so bacteria accumulate toxic levels of lysophospholipids

  • b

    Which one has high rates of GI pain?

    a) Capreomycin

    b) Clofazimine

    c) Bedaquiline

    d) Pretomanid

    e) Ethionamide

  • b

    Which one causes the skin to turn red/brown?

    a) Capreomycin

    b) Clofazimine

    c) Bedaquiline

    d) Pretomanid

    e) Ethionamide

  • c, d

    Which are used for drug-resistant TB?

    a) Capreomycin

    b) Clofazimine

    c) Bedaquiline

    d) Pretomanid

    e) Ethionamide

  • -inhibits mycobacterial proton pump needed to produce ATP

    Bedaquiline MOA?

  • -inhibits cell wall biosynthesis by inhibiting the oxidation of hydroxymycolate to ketomycolate

    Pretomanid MOA?

  • d

    Which can cause the poisoning of bacteria in anaerobic conditions?

    a) Capreomycin

    b) Clofazimine

    c) Bedaquiline

    d) Pretomanid

    e) Ethionamide
