The pharmacokinetics and protein binding of sulfapyridine (SP) and its major metabolite, acetylsulfapyridine (ACSP) were examined in 17 prepubertal children and 4 postpubertal adolescents receiving sulfasalazine (SASP) for treatment of inflammatory bowel disease (IBD). Five patients were studied in both active disease and remission. Comparisons were made with a group of 24 outpatients (9-62 years) with IBD controlled on SASP and in remission. Acetylator phenotype was calculated from plasma metabolite ratios. Slow acetylators had increased plasma concentrations of SP and ACSP + SP (P less than 0.05). Apparent SP clearance (clearance/availability) was increased in active disease (P less than 0.05) and AUCSP + ACSP and AUCSP were decreased (P less than 0.05). There were no age-related alterations in apparent SP clearance. Side effects were frequent but were unrelated to SASP dose, SP concentrations, or acetylator phenotype. Disease activity did not significantly alter the serum protein binding of SP or ACSP. The decreased SP and ACSP concentrations seen in active disease may be due to a combination of disease related alterations in either cleavage of SASP or absorption and clearance of SP.
