💊 Profile

Phthalylsulfathiazole is a sulfonamide with properties similar to those of sulfamethoxazole. It is poorly absorbed, about 95% remaining in the intestine and only about 5% being slowly hydrolysed to sulfathiazole and absorbed. It is given, with other antibacterials, for its antibacterial action in the gastrointestinal tract in the treatment of infections and for bowel decontamination before surgery.
