Cards

Term
differntial uptake of toxic compounds
Definition
paromycin
Term
paromycin use
Definition
protozoal GI tract infections such as Entamoeba and Giardia
Term
Paromycin moa
Definition
no absorbed into human system, stays in GI tract
inhibits protein synthesis by causing tRNA dissociation
Term
tetrahydrofolic acid synthesis inhibitors
Definition
pyrimethamine and sulfonamides
proguanil (andatovaquone)
Term
anaerobic metabolism of pyruvate inhibitor
Definition
metronidazole
Term
pyrimethamine use
Definition
with sulfadoxine
treating chloroquine-resistant malaria
Term
pyrimethamine moa
Definition
inhibits THFA synthesis by inhibiting enzymes
Term
sulfadoxine use
Definition
in combo to treat chloroquine resistant malaria
Term
sulfadoxine moa
Definition
inhibit THFA synthesis by stopping enzymes
Term
proguanil use
Definition
with atovaquone
treatment of malaria
Term
proguanil moa
Definition
THFA synthesis blocker
Term
metronidazole use
Definition
anaerobic bacteria
microaerophillic bacteria and protozoa
Term
metronidazole moa
Definition
inhibits pyruvate metabolism process
damages DNA
Term
normal hemoglobin metabolism
Definition
food vacuoles degrade hemoglobin to energy source and toxic heme
converts heme to nontoxic hemozoin
Term
chloroquine use
Definition
prophylaxis and treatment of malaria
Term
chloroquine moa
Definition
inhibits heme-->hemozoin
free heme becomes toxic to plasmodium cells
Term
chloroquine resistance
Definition
very common
switch between chloroquine and other drugs every 5-10 years
Term
quinine and mefloquine use
Definition
treatment of chloroquine resistant malaria
combo with other drugs
Term
quinine and mefloquine moa
Definition
inhibition of hemozoin formation similar to chloroquine
Term
inhibitor of ETC
Definition
atovaquone
Term
atovaquone use
Definition
treatment and prevention of pneumocystis jirovecii pneumonia (pcp)
Term
atovaquone moa
Definition
binds to protozoal NADH dehydrogenase complex and inhibits electron transport
