Abstract excerpt
Sulfamonomethoxine (S) is metabolized by O-dealkylation, N4-acetylation, and N1-glucuronidation. In humans, only N1-glucuronidation (12%) and N4-acetylation (36%) takes place. The N1-glucuronide is directly measured by HPLC. When N4-acetylsulfamonomethoxine (N4) is administered as the parent drug, N1-glucuronidation does not occur. After an oral dose, fast and slow acetylators show a similar t1/2 for S (25.0 +/-...
