TRITEC Tablets contain a complex of ranitidine, trivalent bismuth, and citrate. Chemically, ranitidine bismuth citrate is N-2-[5-Dimethylaminomethyl-2-furanylmethylthio]ethyl-N'- methyl-2-nitroethenediamine 2-hydroxy-1,2,3- propanetricarboxylate, bismuth (III). Analysis shows that ranitidine bismuth citrate is substoichiometric in ranitidine and citrate.

Ranitidine bismuth citrate is a white to off-white amorphous powder. The approximate molecular formula is [C₁₃H₂₂N₄O₃S] _0.84 Bi[ C₆H₅O₇] _0.94, and the approximate molecular weight is 651. It is readily soluble in water. Each TRITEC Tablet for oral administration contains 400 mg of ranitidine bismuth citrate, equivalent to approximately 162 mg of ranitidine (base), 128 mg of trivalent bismuth, and 110 mg of citrate. Each aqueous film-coated tablet also contains the inactive ingredients FD&C Blue No. 2 Aluminum Lake, magnesium stearate, methylhydroxypropylcellulose, microcrystalline cellulose, Povidone K30, sodium carbonate (anhydrous), titanium dioxide, and triacetin.
