Succinylsulfathiazole is a sulfonamide. It is also spelled as succinylsulphathiazole. It is a white or yellow-white crystalline powder. It dissolves in aqueous solutions of alkali hydroxides and carbonates but is very slightly soluble in water.

It is classified as ultra long acting drug. About 95% of the drug remains in the intestine and only 5% is hydrolyzed, slowly, to Sulfathiazole and is absorbed.

The drug is used for its antibacterial activity in the GIT. The dose is 10g - 20g daily in divided doses.
