Taurolidine
A member of the class of thiadiazinanes that is 1,2,4-thiadiazinane 1,1-dioxide substituted by a (1,1-dioxido-1,2,4-thiadiazinan-4-yl)methyl group at position 4. It is a broad-spectrum antiseptic used as lock therapy solution in patients with long term central venous catheters for the prevention of catheter related bloodstream infections. — ChEBI
