EquiSul-SDT Oral Suspension for Horses

EquiSul-SDT Oral Suspension for Horses

EQUISUL-SDT® is indicated for the treatment of lower respiratory tract infections in horses caused by susceptible strains of Streptococcus equi subsp. zooepidemicus.EQUISUL-SDT is a broad-spectrum antimicrobial from the class of chemotherapeutic agents. These two drugs block different sequential steps in the biosynthesis of nucleic acids. Sulfadiazine inhibits bacterial synthesis of dihydrofolic acid by competing with para-aminobenzoic acid. Trimethoprim blocks the production of tetrahydrofolic acid from dihydrofolic acid by reversibly inhibiting dihydrofolate reductase. The effect of the dual action is to reduce the minimum inhibitory concentration of each agent (synergism) and to convert a bacteriostatic action to a bactericidal action. Following oral administration, EQUISUL-SDT is rapidly absorbed and widely distributed throughout body tissues.
