Description and Uses

Phthalylsulfathiazole is a sulfonamide antibacterial drug with similar and stronger effects than Sulfaguanidine and Succinylsulfathiazole. It is rarely absorbed orally and slowly decomposes in the intestine to release Sulfathiazole and exert intestinal antibacterial effects, and is used in the treatment of dysentery, colitis, and gastroenteritis.
