►  Drug Interaction : Drug interaction of Sulfafurazole is with , Potassium -Sparing Diuretics , , Oral anticoagulants, NSAIDS,  Thiopental Sodium , Procaine, Oral Rehydration Salts , Methotrexate, Phenytoin

  ►    Mechanism of Drug Drug Interaction :  Sulfafurazole has been reported to increase the anaesthetic effect of thiopental. Eye preparations of sulfafurazole diolamine should not be applied with preparations of silver salts. The action of sulfonamides may be antagonised by paminobenzoic acid and its derivatives, particularly potassium aminobenzoate and the procaine group of local anaesthetics. Sulfafurazole and other sulfonamides may potentiate the effects of some drugs, such as oral anticoagulants , methotrexate, and phenytoin; this may be due to displacement of the drug from plasma protein binding sites or to inhibition of metabolism. However, the clinical significance of these interactions appears to depend on the particular sulfonamide involved. The possibility of interactions with other highly protein-bound drugs, such as NSAIDs, should be considered. High doses of sulfonamides have been reported to have a hypoglycaemic effect; the antidiabetic effect of the sulfonylurea compounds may be enhanced by sulfonamides.

►  Contraindication : Hepatic impairment, Renal impairment, Bleeding disorders, Treatment with sulfonamides should be stopped immediately a rash appears because of the danger of severe allergic reactions such as the Stevens-Johnson syndrome., Sulfafurazole should not be given to patients with a history of hypersensitivity to sulfonamides as cross-sensitivity may occur between drugs of this group. Care is generally advisable in patients with a history of allergy or asthma, Caution is also needed in the elderly, who may be more likely to have other risk factors for reactions. Some consider Silver sulphadiazine to be contra-indicated in lupus erythematosus as it may exacerbate the condition., Sulfafurazole and other sulfonamides are not usually given to infants within 1 to 2 months of birth because of the risk of producing kernicterus; for the same reason, they are generally contra-indicated in women prior to delivery, Sulfonamides have been reported to interfere with some diagnostic tests, including those for urea, creatinine, and urinary glucose and urobilinogen.

  ►  Mechanism of Action :   Sulfonamide-susceptible organisms, unlike mammals, cannot use exogenous folate but must synthesize it from PABA. This pathway is thus essential for production of purines and nucleic acid synthesis. As structural analogs of PABA, sulfonamides inhibit dihydropteroate synthase and folate production.
