Amounts to be administered and administration routeAdministration route: Oral use.Posology:5 mg trimethoprim and 25 mg sulfadiazine per kg body weight per day to a maximum of 5 days.One syringe is intended for 600 kg bodyweight and each syringe is subdivided into 12 markings. The equivalent of one marking is sufficient to treat 50 kg of bodyweight and the minimum body weight for treatment is 50 kg.Directions for useHorse weight should be accurately determined for the correct use of the paste.The calculated dose is provided by adjusting the ring on the plunger according to the body weight of the horse.The paste is administered orally by inserting the nozzle of the syringe through the interdental space and depositing the required amount of paste on the back of the tongue. The animal’s mouth should be free of any food. Immediately after administration, elevate the head of the horse for a few seconds to ensure the dose is swallowed.4.10 Overdose (symptoms, emergency procedures, antidotes), if necessaryNot known.

Withdrawal period(s)Meat and offal: 14 daysNot permitted for use in mares producing milk for human consumption.Pharmacodynamic propertiesBoth active substances produce a sequential double blockade of bacterial synthesis of folic acid. This results in a synergistic and bactericidal action inhibiting sequential steps in the synthesis of purines, which are required for DNA synthesis. The combination has a broad action against many Gram-positive and Gram-negative bacteria such as staphylococci, streptococci and E.coli.Pharmacokinetic particularsAfter a single oral administration of 5 mg trimethoprim and 25 mg sulfadiazine per kg body weight to horses, the following parameters (mean ± sd) were observed:Food intake appeared to affect the pharmacokinetic profile as both trimethoprim and sulfadiazine have been absorbed more rapidly in fasted horses.Excretion of both actives is chiefly by the kidneys, by both glomerular filtration, and tubular secretion.Urine concentrations of both trimethoprim and sulfadiazine are severalfold higher than bloodconcentrations. Neither trimethoprim nor sulfadiazine interferes with the excretion pattern of the other.
