Chemistry - A synthetic nitrofuran-derivative antibacterial/antiprotozoal,
furazolidone occurs as a bitter-tasting, yellow, crystalline powder. It is
practically insoluble in water. Storage/Stability/Compatibility - Store
protected from light in tight containers. Do not expose the suspension to
excessive heat. Pharmacology - Furazolidone interferes with susceptible
bacterial enzyme systems. Its mechanism against susceptible protozoa is not well
determined. Furazolidone has activity against Giardia, Vibrio cholerae,
Trichomonas, Coccidia and many strains of E. Coli, Enterobacter, Campylobacter,
Salmonella and Shigella. Not all strains are sensitive, but resistance is
usually limited and develops slowly. Furazolidone also inhibits monoamine
oxidase. Uses/Indications - Furazolidone is usually a drug of second
choice in small animals to treat enteric infections caused by the organisms
listed above. Pharmacokinetics - Conflicting information on
furazolidone’s absorption characteristics are published. As colored metabolites
are found in the urine, it is clearly absorbed to some extent. Because
furazolidone is used to treat enteric infections, absorption becomes important
only when discussing adverse reactions and drug interaction issues. Furazolidone
is reported to be distributed into the CSF. Absorbed furazolidone is rapidly
metabolized in the liver and the majority of absorbed drug is eliminated in the
urine. (http://www.elephantcare.org/)
Furazolidone
(FZD) is a synthetic nitrofuran derivative that is an
antibacterial and antiprotozoal agent. FZD occurs as
a yellow odorless crystalline powder with a bitter aftertaste.
The drug is practically insoluble in water and alcohol.
FZD is decomposed by alkali. The drug should be protected
by light because it darkens on exposure to strong light
and thus should be stored in light resistant containers.
FZD is active against the protozoan Giardia lamblia
(Giardia intestinalis) and against a range of bacteria
in vitro including staphylococci, enterococci, Escherichia
coli, Salmonella spp., Shigella spp., and Vibrio cholerae.
FZD is bactericidal and appears to act by interfering
with bacterial enzyme systems. Resistance is reported
to be limited. It is used in the treatment of giardiasis,
trichomoniasis, cholera and other vibrio infections1.
It has been suggested for other bacterial gastrointestinal
infections but antibacterial therapy with FZD is regarded
as unnecessary in mild & self-limiting gastro-enteritis.1
However, FZD has been reported to possess anti-Helicobacter
activity2 and to have some ulcer-healing properties.

Nitrofuran
: one of a group of synthetic antimicrobials used to treat
infections caused by protozoa or by certain gram-positive or gram-negative
bacteria. The precise mechanism by which nitrofurans exert their antimicrobial
effects is not known, but several bacterial and protozoal enzyme systems are
inhibited. Two agents commonly prescribed are furazolidone and nitrofurantoin.
Furazolidone is used to treat bacterial and protozoal diarrhea and enteritis.
Nitrofurantoin is used to treat urinary tract infections caused by
Escherichia coli and other enteric pathogens of the urinary tract.
Systemic administration of nitrofurans is associated with many side effects, the
most common being nausea and diarrhea. Serious side effects include
polyneuropathies and several hypersensitivity reactions, including pneumonitis
and blood dyscrasias. Nitrofurans can cause hemolytic anemia in patients with
glucose-6-phosphate dehydrogenase deficiency. Lastly, they cause a harmless
brown discoloration of the urine. (http://medical-dictionary.thefreedictionary.com/)
