The clinical and anti-inflammatory effects of a single treatment of 0·4 mg meloxicam/kg bodyweight on pigs that had been challenged with Escherichia coli endotoxin were investigated. Significantly lower total clinical scores were recorded in pigs treated with meloxicam than in pigs treated with a placebo. Significantly higher mean serum concentrations of thromboxane B2 were also recorded in pigs treated with a placebo for up to 24 hours after the challenge. The serum concentrations of acute phase proteins and specific antibody titres to E coli lipopolysaccharide were unaffected by the meloxicam. The meloxicam treatment was well tolerated.
