Pracetam 20% O. S.This treatment applies to the following species:
Acetaminophen oral solution for swine
Veterinary use only
Pracetam 20% O. S. Indications
To reduce fever and associated clinical symptoms in cases of acute respiratory disease in swine.
WarningTreated swine must not be slaughtered for use in food for at least 3 days after the latest treatment with this drug. Keep out of reach of children.
Dosage and Administration
30 mg of acetaminophen/kg bodyweight/day (1.5 mL Pracetam 20% O. S./10 kg/d) administered continuously in drinking water for 5 days. Only medicated drinking water should be provided during the treatment period. Fresh solutions should be prepared daily because the product is stable only for 24 hours once diluted in water.
The following recommendations for dilution of the product are based on an average daily water consumption equivalent to 10% of bodyweight (i.e. a group of swine weighing a total of 1000 kg and drinking 100 L of water per 24 hours). If the daily water consumption is higher or lower, calculations should be made with the actual water consumption in order to supply swine with an average of 30 mg of acetaminophen/kg bodyweight/day.
Prepare a stock solution by mixing 1 part of Pracetam 20% O. S. with 19 parts of lukewarm water. This is equivalent to 50 mL of Pracetam 20% O. S. per L of stock solution, or 10 g of acetaminophen per L of stock solution.
To treat 1000 kg of swine, prepare 3 L of stock solution by mixing 150 mL of Pracetam 20% O. S. with 2.85 L of water.
Set the apparatus at 3% (30 mL of stock solution per L of drinking water).
Note: the solubility threshold of Pracetam 20% O. S. in water at 5°C is 6% (60 mL of Pracetam 20% O. S. per L of stock solution) and 12% in water at 20°C. Should you need to adjust the concentration of the stock solution in function of the daily water consumption for swine to be treated, do not go over these concentrations otherwise the solution would be at risk of precipitation.
Do not use in animals with known hypersensitivity to acetaminophen, with severe hepatic impairment or with severe renal impairment.
CAUTIONS: The safety of this product has not been verified in breeding animals.
Clinical PharmacologyOral absorption of acetaminophen is fast and almost complete (bioavailability close to 90% after administration in drinking water). Maximum concentrations are reached within a bit less than 2 hours after administration. Acetaminophen is metabolised by the liver and eliminated mainly in urine.
EFFICACY: A multicenter randomized double blind clinical field trial was conducted on 122 fattening pigs with rectal temperature ≥ 40°C and signs of influenza syndrome (dyspnea and/or polypnea, demeanour, and anorexia). The protocol was respected for 79 animals and data from these pigs were used for analysis (39 Pracetam 20% O. S. and 40 Placebo). Pracetam 20% O. S. was administered in drinking water as per label recommendations for 5 days. Differences in rectal temperature and in adjusted difference in clinical score (based on general condition, respiration, coughing and sneezing) were statistically significant between the two groups in favour of the Pracetam 20% O. S. group.
STORAGE CONDITIONS: Store at or below 30°C with minor temperature excursions to 40°C.
