ERZOFRI (paliperidone palmitate) extended-release injectable suspension contains a racemic mixture of (+)- and (-)- paliperidone palmitate. Paliperidone palmitate, is an atypical antipsychotic belonging to the chemical class of benzisoxazole derivatives. The chemical name is (9 RS )-3-[2-[4-(6-Fluoro-1,2-benzisoxazol-3-yl)piperidin-1-yl]ethyl]-2-methyl-4-oxo-6,7,8,9-tetrahydro-4 H -pyrido[1,2- a ]pyrimadin-9-yl hexadecanoate. Its molecular formula is C 39 H 57 FN 4 O 4 and its molecular weight is 664.89. The structural formula is: Paliperidone palmitate is very slightly soluble in ethanol and methanol, practically insoluble in water, and slightly soluble in ethyl acetate. ERZOFRI is available as a white to off-white sterile aqueous extended-release suspension for intramuscular injection in the following dose strengths of paliperidone palmitate (deliverable volume) in single-dose prefilled syringes: 39 mg (0.25 mL), 78 mg (0.5 mL), 117 mg (0.75 mL), 156 mg (1 mL), 234 mg (1.5 mL), and 351 mg (2.25 mL). The drug product hydrolyzes in vivo to the active moiety, paliperidone, resulting in dose strengths of 25 mg, 50 mg, 75 mg, 100 mg, 150 mg, and 225 mg of paliperidone, respectively. The inactive ingredients are citric acid monohydrate (5 mg/mL), dibasic sodium phosphate anhydrous (5 mg/mL), monobasic sodium phosphate monohydrate (2.5 mg/mL), polyethylene glycol 4000 (30 mg/mL), polysorbate 20 (12 mg/mL), sodium hydroxide to adjust pH, and water for injection. The drug product pH is 6.5 to 7.5. Chemical Structure
