=== Use in humans ===
 
In humans it has used to treat [[diarrhoea]] and [[enteritis]] caused by [[bacteria]] or [[protozoa]]n infections. It has been used to treat traveler's diarrhoea, [[cholera]] and [[salmonella|bacteremic salmonellosis]].

As for all medicines the most recent local recommendations for its use should be always be followed. The usual dose is:

* Child: 1.25 mg/kg 4 times daily, usually given for 2-5 days or up to 10 days for giardiasis.

'''Furazolidone''' is an [[antibiotic]] used to treat [[diarrhea]] and [[enteritis]] caused by [[bacteria]] or [[protozoa]]n infections. It is marketed by Roberts Laboratories under the brand name '''Furoxone''' and by [[GlaxoSmithKline]] as Dependal-M.


Furazolidone is also used in combination with fluids for treatment of acute infantile diarrhea. Furazolidone is also used to treat traveler's diarrhea, [[cholera]], and [[salmonella|bacteremic salmonellosis]].
===Use in laboratory===


As a [[veterinary medicine]], furazolidone has been used with some success to treat [[salmon]]ids for ''[[Myxobolus cerebralis]]'' infections. This drug is commonly prescribed to infants and children in oral suspension. The drug is the most common treatment of diarrhea caused by water borne diseases.  
It is used to differentiate [[micrococcus|micrococci]] and [[staphylococcus|staphylococci]].


==Mechanism==
It is believed to work by [[crosslinking of DNA]].<ref name="urlDrugBank: Showing Furazolidone (DB00614)">{{cite web |url=http://www.drugbank.ca/drugs/DB00614 |title=DrugBank: Showing Furazolidone (DB00614) |format= |work= |accessdate=2008-12-19}}</ref>


==Side effects==
Furazolidone is no longer available in the US. Though an effective antibiotic when all others fail, against extremely drug resistant infections, it has many side effects, and as with other [[nitrofuran]]s generally, [[minimum inhibitory concentration]]s also produce systemic toxicity (tremors, convulsions, peripheral neuritis, gastrointestinal disturbances, depression of spermatogenesis.)

Overview

Furazolidone is a nitrofuran antibacterial. It is marketed by Roberts Laboratories under the brand name Furoxone and by GlaxoSmithKline as Dependal-M. Diafuron, medaron

Uses

Furazolidone has been used in human and veterinary medicine. It has a broad spectrum of activity being active against

Use in humans

In humans it has used to treat diarrhoea and enteritis caused by bacteria or protozoan infections. It has been used to treat traveler's diarrhoea, cholera and bacteremic salmonellosis. Use in treating Helicobacter pylori infections has also been proposed.[1]

Furazolidone is also used for giardiasis (due to Giardia lamblia), though it is not a first line treatment.[2]

As for all medicines the most recent local recommendations for its use should be always be followed. The usual dose is:

  • Adult: 100 mg 4 times daily. Usual duration: 2-5 days, up to 7 days in some patients or 10 days for giardiasis.
  • Child: 1.25 mg/kg 4 times daily, usually given for 2-5 days or up to 10 days for giardiasis.

Use in animals

As a veterinary medicine, furazolidone has been used with some success to treat salmonids for Myxobolus cerebralis infections.

It has also been used in aquaculture.[3]

Since furazolidone is a nitrofuran antibiotic, its use in food animals is currently prohibited by the FDA under the Animal Medicinal Drug Use Clarification Act, 1994.[4]

Use in laboratory

It is used to differentiate micrococci and staphylococci.

Mechanism

It is believed to work by crosslinking of DNA.[5]

Side effects

Furazolidone is no longer available in the US. Though an effective antibiotic when all others fail, against extremely drug resistant infections, it has many side effects, and as with other nitrofurans generally, minimum inhibitory concentrations also produce systemic toxicity (tremors, convulsions, peripheral neuritis, gastrointestinal disturbances, depression of spermatogenesis.) Nitrofurans are recognized by FDA as mutagens/carcinogens, and can no longer be used since 1991.[6]
