Ormetoprim is an antibiotic used in veterinary medicine. Typically it is used in combination with sulfadimethoxine, and it is used in the poultry^[1] and aquaculture industries.^[2]

Ormetoprim, like other diaminopyrimidines such as trimethoprim, inhibits the reduction of dihydrofolic acid to tetrahydrofolic acid by bacterial cells.^[3]
