Pharmacological properties

Pharmacotherapeutic group: other analgesics and antipyretics

ATCvet code: QN02BE01

5.1 Pharmacodynamic properties

Paracetamol, or acetaminophen is a para amino-phenol derivative with analgesic and antipyretic properties. Its antipyretic effect may be explained by its ability to inhibit brain cyclo-oxygenases. Paracetamol is only a weak inhibitor of COX-1 synthesis and, thus, has no gastrointestinal side-effects and has no effect on platelet-aggregation.

5.2 Pharmacokinetic particulars

Absorption and distribution: After a single oral administration of PRACETAM in feed, at 15 mg/kg, the bioavailability is 76 %, the peak of paracetamol concentration (cmax), 3.6 µg/ml, is reached 2.4 hours after the administration.

Metabolism: Paracetamol is metabolised mostly in the liver. The two major metabolic pathways are glucuronide conjugation and sulphate conjugation. A minor pathway catalysed by CYP (cytochrome P450) leads to the formation of the intermediary reagent, N-acetyl benzoquinoneimine which, is rapidly detoxified by reduced glutathione and removed in urine after conjugation with cystein and mercapturic acid.

Elimination: Paracetamol is essentially eliminated through urine (70 % of a single dose is eliminated via urine within 24 hours) under the form of paracetamol glucuronide (80 %). The other forms of elimination are cystein (10 %), unchanged paracetamol and sulphate.

Target species

Pigs (weaned pigs).

Indications

Pigs (weaned pigs) :

Symptomatic treatment for reduction of pyrexia, in the context of acute infectious respiratory diseases, in combination with appropriate anti-infective therapy.

Dosage

The daily dose is 30 mg per kg b.w. for 5 consecutive days to be administered in feed: The dose can be administered in dry feed supplied in two meals.

The product may be administered in pellets as well as non-pelleted feed.

For the preparation of medicated feed:

30 mg Paracetamol per kg b.w. daily corresponds to 300 mg “Pracetam 10 % Premix” per kg b.w. daily.

For the preparation of the medicated feed the body weight of the animals to be treated and their actual daily intake of feed should be taken into due account. To provide the required amount of active substance per kg medicated feed the premix has to be incorporated into the feed according to the following formula:

300 mg “Pracetam 10 %” per kg b.w. daily X average body weight (kg) of the animals to be treated

---------------------------------------------------------------------------------------------

= mg “Pracetam 10 %” per kg feed

average daily feed intake per animal (kg)

The mixing should be performed in an (authorised) feedingstuff manufacture with adequate mixing apparatus.
