Term
2 main drugs to kill Trypanosoma gambiense
Definition
Melarsoprol, Eflornithine
Term
Main drug to treat Trypanosoma cruzi
Definition
Nifurtimox
Term
Polysulfonated naphthyl urea. inhibits several parasytic enzymes, exact mechanism unknown
Definition
Suramin
Term
DNA and RNA polymerase inhibition? Oxidative phosphorylation inhibitor?
Definition
Pentamidine
Term
Trivalent arsenical that binds to and inhibits parasitic enzymes. Especially SULFHYDRYL groups (more sensitive to parasitic enzymes than the host).
Definition
Melarsoprol
Term
Used in later stages of CNS involvement. Given IV 70% appers in feces due to rapid excretion
Definition
Melarsoprol
Term
Trivalent arsenical binds to parasytic enzymes
Definition
Melarsoprol
Term
Parenteral formulation available from WHO.
Inhibits polyamine biosynthesis in Trypanosoma.

Inhibitor of ornithine decarboxylase is effective and greatest hope for late stage trypanosomiasis.
Definition
Eflornithine
Term
Eliminated by kidneys. Wide range of hematological adverse effects. Topical formulation available for reducing unwanted facial hair in women (Vaniqa)
Definition
Eflornithine
Term
Vaniqa : topical formulation for reducing unwanted facial hair in women
Definition
Eflornithine
Term
suppressive and possibly curative. *Produces intracellular free radicals that kill organism*
Definition
Nifurtimox
Term
Used at chronic stages of disease (trypanosoma) with minimal effects.
oral administratoin w/ biotransformation and metabolites excreted by kidneys.
Definition
Nifurtimox
Term
binds to proteins and DNA (electron acceptor) of flagellate
Definition
Metronidazole (Flagyl)
Term
amebicidal, bactericidal, trichomonacidal. Disrupts DNAs tertiary structure and inhibits nucleic acid synthesis.
Anaerobic organisms and cells
Definition
Tinidazole
Term
Binds to membrane phospholipids of flagellate. Crosses placenta.
Definition
Quinacrine
Term
Oral synthetic antiprotozoal agent for treatment of cryptosporidosis or giardiasis

Nitazoxanide
Term
Treatment strategy for Giardia uses
Definition
Metrondiazole and Tinidazole
Term
Causes disulfram like reaction, if you drink alcohol you will throw up!!
Definition
Metrondiazole
Term
Less disulfram like reaction disrupts DNA tertiary structure inhibiting DNA synthesis . Very effective vs. anaerobic organisms
Definition
