Pigs are unable to form N1-glucuronides of sulphadimethoxine and sulphamethomidine, while humans are able to do so. Pigs and humans are able to oxidise sulphapyridine and form the O-glucuronide. The double conjugate N4-acetylsulphapyridine-O-glucuronide is formed in humans but not in pigs. Sulphadiazine is mainly acetylated in both humans and pigs. A hypothesis about N1-glucuronidation is presented.
