適応症
Iodoquinol (diiodohydroxyquin, Yodoxin, Moebiquin)
is a halogenated 8-hydroxyquinoline derivative whose
precise mechanism of action is not known but is thought
to involve an inactivation of essential parasite enzymes.
Iodoquinol kills the trophozoite forms of E. histolytica,
B. coli, B. hominis, and Dientamoeba fragilis.
Iodoquinol is absorbed from the gastrointestinal
tract and is excreted in the urine as glucuronide and sulfate
conjugates. Most of an orally administered dose is
excreted in the feces. Iodoquinol has a plasma half-life
of about 12 hours.
Iodoquinol is the drug of choice in the treatment of
asymptomatic amebiasis and D. fragilis infections. It is
also used in combination with other drugs in the treatment
of other forms of amebiasis and as an alternative
to tetracycline in the treatment of balantidiasis.
Adverse reactions are related to the iodine content
of the drug; the toxicity is often expressed as skin reactions,
thyroid enlargement, and interference with thyroid
function studies. Headache and diarrhea also occur.
Chronic use of clioquinol, a closely related agent,
has been linked to a myelitislike illness and to optic atrophy
with permanent loss of vision.

臨床応用
5,7-Diiodo-8-quinolinol, 5,7-diiodo-8-hydroxyquinoline,or diiodohydroxyquin (Yodoxin, Diodoquin, Diquinol) is ayellowish to tan microcrystalline, light-sensitive substancethat is insoluble in water. It is recommended for acute andchronic intestinal amebiasis but is not effective in extraintestinaldisease. Because a relatively high incidence of topicneuropathy has occurred with its use, iodoquinol should notbe used routinely for traveler’s diarrhea.
