Meropenem, present as a trihydrate, is a white to light yellow crystalline powder, with a molecular weight of 437.52. The chemical name for meropenem trihydrate is (4 R ,5 S ,6 S )-3-[[(3 S ,5 S )-5-(dimethylcarbamoyl)-3-pyrrolidinyl]thio]-6-[(1 R )-1-hydroxyethyl]-4-methyl-7-oxo-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylic acid, trihydrate. The empirical formula of meropenem trihydrate is C 17 H 25 N 3 O 5 S∙3H 2 O and its chemical structure is: Figure 1: Structure of Meropenem Trihydrate Vaborbactam is a white to off-white powder, with a molecular weight of 297.14. The chemical name for vaborbactam is (3 R ,6 S )-2-hydroxy-3-[[2-(2-thienyl)acetyl]amino]-1,2-oxaborinane-6-acetic acid. Its empirical formula is C 12 H 16 BNO 5 S and its chemical structure is: Figure 2: Structure of Vaborbactam VABOMERE is supplied as a white to light yellow sterile powder for constitution that contains meropenem trihydrate, vaborbactam, and sodium carbonate. Each 50 mL glass vial contains 1 gram of meropenem (equivalent to 1.14 grams of meropenem trihydrate), 1 gram of vaborbactam, and 0.575 gram of sodium carbonate. The total sodium content of the mixture is approximately 0.25 grams (10.9 mEq)/vial. Each vial is constituted and further diluted with 0.9% Sodium Chloride Injection, USP. Both the constituted solution and the diluted solution for intravenous infusion should be a colorless to light yellow solution [see Dosage and Administration (2.3) ].
