TARGET SPECIES: Bovine, Equine, Poultry, Swine, Others: Horses, Calves, Pigs and Poultry PHARMACODYNAMICS: Sulfadimidine is a pyrimidine sulphonamide antimicrobial agent. Sulfonamides, being structural analogues of para-aminobenzoic acid (PABA), competitively inhibit the incorporation of PABA into dihydropteric acid, the precursor of folic acid. Subsequent reduction in the level of folic acid reduces the production of nucleic acids in sensitive bacteria. Mammalian cells require preformed folic acid and thus are unaffected by sulphonamides. The antibacterial actions of sulphonamides are reduced in the presence of blood, pus and tissue breakdown products, which contain purines and thymidine, as the bacterial requirement of folic acid is decreased in such media. Trimethoprim is a diaminopyrimidine antimicrobial agent. It acts by preventing the reduction of dihydrofolate to tetrahydrofolate which is required by bacteria for biosynthesis of purines, pyrimidines and some amino acids. Sulfadimidine and trimethoprim have similar antibacterial spectra, trimethoprim being approximately 20 times more potent than sulfadimidine. The combination blocks two sequential obligate enzymatic reaction in the microbial folate synthetic pathway, A synergistic action is demonstrated by the enhanced antimicrobial activity (potentiation) of the combination compared with the antimicrobial activity of either agent singly. The minimum inhibitory (MICs) of the combination for susceptible bacteria are substantially lower than those of either of the individual agents. The combination of sulphonamide/trimethoprim is bactericidal while either drug alone is bacterionstatic. Folate-synthesising bacteria which are resistant or moderately resistant to either drug alone are frequently susceptible to the combinati Lees het volledige document
