Powder for Injection



A Homogeneous powder of light yellow color with a weak specific smell


1 ml contains active substances:

Sulfadimethoxine sodium salt – 300 mg;

Sulfadiazine sodium salt – 300 mg;

Trimethoprim – 120 mg.


The mechanism of action of the drug that contains sulfonamides and trimethoprim provides blocking of two successive stages of the biosynthesis of folic acid in the bacterial cell. This leads to inhibition of bacterial growth, propagation, and termination of their death.

The combination of two sulfonamides and original diaminopyrimidine (trimethoprim) provides a synergistic effect that extends the antimicrobial spectrum of activity against gram-positive and gram-negative bacteria (Staphylococcus spp., Streptococcus spp., Neisseria spp., Clostridium spp., Listeria monocytogenes, Corynebacterium spp., E. coli, Salmonella spp., Klebsiella spp., Proteus spp., Citrobacter spp., Pasteurella spp., Bordetella spp, Enterobacter spp., Yersinia enterocolitica, chlamydia spp., Vibrio cholera, etc.). Some protozoa are also sensitive to components of the drug (Pneumocystis carinii, Coccidia, and Toxoplasma). This combination of sulfonamides and trimethoprim reduces the probability of resistant strains of pathogenic organisms
