代谢
N1-乙酰磺胺异噁唑通过消化道中的消化酶代谢为磺胺异噁唑,并以磺胺异噁唑的形式被吸收。这种酶切裂假定为吸收较慢和达到较低的血药峰浓度,这比等量口服磺胺异噁唑的给药后的浓度要低。随着乙酰磺胺异噁唑的持续给药,血药浓度接近磺胺异噁唑的浓度。/乙酰磺胺异噁唑/
N1-acetyl sulfisoxazole is metabolized to sulfisoxazole by digestive enzymes in the gastrointestinal tract and is absorbed as sulfisoxazole. This enzymatic splitting is presumed to be responsible for slower absorption and lower peak blood concentrations than are attained following administration of an equal oral dose of sulfisoxazole. With continued administration of acetyl sulfisoxazole, blood concentrations approximate those of sulfisoxazole. /Acetyl-sulfisoxazole/
