INVEGA TRINZA™ contains a racemic mixture of (+)- and (-)- paliperidone palmitate. The chemical name is (9RS)-3-[2-[4-(6-Fluoro-1,2-benzisoxazol-3-yl)piperidin-1-yl]ethyl]-2-methyl-4-oxo-6,7,8,9-tetrahydro-4H-pyrido[1,2-a]pyrimadin-9-yl hexadecanoate. Its molecular formula is C39H57FN4O4 and its molecular weight is 664.89. The structural formula is:
Paliperidone palmitate is very slightly soluble in ethanol and methanol, practically insoluble in polyethylene glycol 400 and propylene glycol, and slightly soluble in ethyl acetate.
