Product properties


Each kg of premix contains: 250 g Sulfadimethoxine & 50 g Ormetoprim

Mechanism of Action:

Sulfadimethoxine belongs to the family of sulfonamides and prevents the conversion of para-amino benzoic acid to dihydrofolic acid. Ormetoprim prevents dihydrofolic acid from interfering with the nucleic acid production process. These two substances are bactericidal with synergistic effect on each other. And they are effective against most gram-positive and gram-negative bacteria such as Edwardsiella, Aeromonas, Vibrio and Staphylococcus in aquatic animals, especially salmon and trout.
