11.1 Chemical Characteristics Iodixanol injection, USP is a dimeric, iso-osmolar, nonionic, water-soluble, radiographic contrast medium for intravascular (intravenous and intra-arterial) use. It is provided as a ready-to-use sterile, pyrogen-free, and preservative free, colorless to pale yellow solution. The chemical formula is 5,5´-[(2-hydroxy-1,3-propanediyl) bis(acetylimino)] bis[N,N´-bis(2,3-dihydroxypropyl)-2,4,6-triiodo-1,3-benzenedicarboxamide] with a molecular weight of 1,550.18 (iodine content 49.1%). Iodixanol (C 35 H 44 I 6 N 6 O 15 ) has the following structural formula: Iodixanol injection, USP is available in two strengths: Iodixanol Injection, USP, 270 mg Iodine/mL (550 mg Iodixanol/mL), 0.074 mg calcium chloride dihydrate, 1.87 mg sodium chloride, 1.2 mg tromethamine, and 0.1 mg edetate calcium disodium. Iodixanol Injection, USP, 320 mg Iodine/mL (652 mg Iodixanol/mL), 0.044 mg calcium chloride dihydrate, 1.11 mg sodium chloride, 1.2 mg tromethamine and 0.1 mg edetate calcium disodium. Sodium chloride and calcium chloride have been added, resulting in an isotonic solution for injection providing for both concentrations a sodium/calcium ratio equivalent to blood. The pH is adjusted to 7.4 with hydrochloric acid and/or sodium hydroxide to achieve a range between pH 6.8 and 7.7 at 22°C. Structure 11.2 Physical Characteristics The two concentrations of iodixanol injection, USP (270 mg Iodine/mL and 320 mg Iodine/mL) have the following physical properties: TABLE 4 Physical Properties of Iodixanol Injection, USP Parameter Concentration (mg Iodine/mL) 320 270 Osmolality (mOsmol/kg water) 290 290 Viscosity (cP) @ 20°C 26.6 12.7 @ 37°C 11.8 6.3 Density (g/mL) @ 20°C 1.369 1.314 @ 37°C 1.356 1.303 DESCRIPTION Betamethasone Sodium Phosphate and Betamethasone Acetate Injectable Suspension is a sterile aqueous suspension containing 3 mg per milliliter betamethasone, as betamethasone sodium phosphate, and 3 mg per milliliter betamethasone acetate. Inactive ingredients per mL: 7.1 mg dibasic sodium phosphate anhydrous; 3.4 mg monobasic sodium phosphate monohydrate; 0.1 mg edetate disodium; and 0.2 mg benzalkonium chloride as a preservative. The pH is adjusted to between 6.8 and 7.2. The formula for betamethasone sodium phosphate is C 22 H 28 FNa 2 O 8 P and it has a molecular weight of 516.40. Chemically, it is 9-Fluoro-11β,17,21-trihydroxy-16β-methylpregna-1,4-diene-3,20-dione 21-(disodium phosphate). The formula for betamethasone acetate is C 24 H 31 FO 6 and it has a molecular weight of 434.50. Chemically, it is 9-Fluoro-11β,17,21-trihydroxy-16β-methylpregna-1,4-diene-3,20-dione 21-acetate. The chemical structures for betamethasone sodium phosphate and betamethasone acetate are as follows: Structural Formula Structural Formula Betamethasone sodium phosphate is a white to practically white, odorless powder, and is hygroscopic. It is freely soluble in water and in methanol, but is practically insoluble in acetone and in chloroform. Betamethasone acetate is a white to creamy white, odorless powder that sinters and resolidifies at about 165ºC, and remelts at about 200ºC to 220ºC with decomposition. It is practically insoluble in water, but freely soluble in acetone, and is soluble in alcohol and in chloroform.
