Definition of sulfadimidine in US English:


(British sulphadimidine)


  • A sulfonamide antibiotic used chiefly to treat human urinary infections and to control respiratory disease in pigs.

    • ‘Sulfonamides currently used in veterinary medicine are sulfaquinoxaline, sulfadimidine, sulfamethazine, sulfadimethoxine, sulfachlorpyrazine and sulfathiazole.’
    • ‘The study therefore concludes that, acute starvation can raise the tissue concentrations of sulphadimidine in rabbits and the safe withdrawal time following the administration of the drug should be in excess of twelve days.’
    • ‘One problem the NRA found was that historically recommended dose rates for oral treatment of coccidiosis in sheep with sulfadimidine have varied markedly.’
    • ‘The results obtained in this study suggest that the activity of enzymes involved in the metabolism of sulphadimidine increased with the age of calves.’
    • ‘Therefore, a high-performance liquid chromatography method was developed to assay sulfadimidine.’


1950s: from sulfa- + di- + pyrimidine.
