Antibacterial drug. Ormetoprim sulfadimethoxine is a synergistic combination similar to trimethoprim sulfonamide combinations. Ormetoprim inhibits bacterial dihydrofolate reductase, and sulfonamide competes with para-aminobenzoic acid (PABA) for synthesis of nucleic acids. Bactericidal/bacteriostatic. It has a broad antibacterial spectrum that includes common gram-positive and gram-negative bacteria. It also is active against some coccidia.
Ormetoprim + sulfadimethoxine is used in small animals to treat a variety of bacterial infections caused by susceptible organisms, including pneumonia, skin, soft tissue, and UTIs in dogs and cats. In horses, it may be administered orally for infections caused by susceptible gram-positive bacteria (Actinomyces, Streptococcus spp., and Staphylococcus spp.), but higher doses may be needed for gram-negative infections.
