Description and Uses
Sulfamethizole is a broad spectrum sulfonamide antibiotic (MIC90s = 1.25-5,000 μg/ml against clinical isolates of E. coli and K. pneumoniae). It inhibits dihydropteroate synthase, an enzyme involved in folate biosynthesis. Formulations containing sulfamethizole have previously been used to treat urinary tract infections.
This drug has antibacterial activity with respect to streptococci, pneumococci, staphylococci, meningococci, gonococci, colon bacillus, pathogenic dysentery, and others. It is not very toxic. It is generally used for acute, uncomplicated infections of the urinary tract that are caused by sensitive organisms. Because it is removed quickly from the organism by the kidneys, the level of drug in the plasma remains low, and therefore it is not used for treating infections that are localized in the urinary tract. Sulfisoxazole is the more preferred drug. Synonyms of this drug are urosol, rufol, thiosulfil, and others.
