N-acetyltransferase 2 genotype-related sulfapyridine acetylation and its adverse events.


Sulfapyridine (SP), one of the metabolites of sulfasalazine (SASP), is further metabolized into N-acetylsulfapyridine (AcSP) by polymorphic N-acetyltransferase 2 (NAT2). NAT2 activity has been diagnosed by phenotyping, that is, evaluating plasma concentrations or urinary excretions of tentatively administered test drugs for dose individualization and… (More)
