Sulphamethoxazole and its metabolite, N4-acetylsulphamethoxazole, were shown to cross the placenta of a pregnant ewe. The plasma concentration of N4-acetylsulphamethoxazole increased in the foetus due to the limited elimination properties of the immature kidney. The amniotic fluid concentration of sulphamethoxazole

Plasma and urine concentrations of creatinine, sulphamethoxazole and its metabolite N4-acetylsulphamethoxazole were measured in patients with varying degrees of kidney impairment. The plasma elimination half-life of sulphamethoxazole is not influenced by the kidney function, while the half-life of the metabolite
