VYALEV injection is a solution that is a combination of foscarbidopa (carbidopa-4´-monophosphate) and foslevodopa (levodopa-4´-monophosphate). Foscarbidopa and foslevodopa are prodrugs that undergo enzymatic bioconversion via intrinsic alkaline phosphatase to carbidopa and levodopa, respectively, in vivo . Foscarbidopa, an inhibitor of aromatic amino acid decarboxylation, is a white to light yellow powder, freely soluble in aqueous media, with a molecular weight of 306.21 g/mol anhydrous. It is designated chemically as (2 S )-2-hydrazinyl-3-[3-hydroxy-4-(phosphonooxy)phenyl]-2-methylpropanoic acid trihydrate. Its empirical formula is C 10 H 15 N 2 O 7 P (anhydrous basis), and its structural formula is: Foslevodopa, an aromatic amino acid, is a white to off-white powder, freely soluble in aqueous media, with a molecular weight of 277.17 g/mol. It is designated chemically as (2 S )-2-amino-3-[3-hydroxy-4-(phosphonooxy)phenyl] propanoic acid. Its empirical formula is C 9 H 12 NO 7 P, and its structural formula is: VYALEV (foscarbidopa and foslevodopa) injection is a sterile, preservative-free solution for subcutaneous infusion. VYALEV is supplied in a 10 mL single-dose glass vial that contains 120 mg foscarbidopa and 2,400 mg foslevodopa per 10 mL (12 mg foscarbidopa and 240 mg foslevodopa per mL). VYALEV may contain sodium hydroxide and/or hydrochloric acid to adjust the pH to approximately 7.4.
