Methylprednisolone Sodium Succinate for Injection, USP sterile powder is an anti-inflammatory glucocorticoid, which contains methylprednisolone sodium succinate as the active ingredient. Methylprednisolone sodium succinate, USP, is the sodium succinate ester of methylprednisolone, and it occurs as a white, or nearly white, odorless hygroscopic, amorphous solid. It is very soluble in water and in alcohol; it is insoluble in chloroform and is very slightly soluble in acetone. The chemical name for methylprednisolone sodium succinate is pregna-1,4-diene-3,20- dione, 21-(3-carboxy-1-oxopropoxy)-11, 17-dihydroxy-6-methyl-monosodium salt, (6α, 11β). The structural formula is represented below: Methylprednisolone sodium succinate is soluble in water; it may be administered in a small volume of diluent and is well suited for intravenous use in situations where high blood levels of methylprednisolone are required rapidly. Methylprednisolone Sodium Succinate for Injection, USP is available in three strengths for intravenous or intramuscular administration. 40 mg (Single - Dose Vial) Each mL (when mixed as directed) contains methylprednisolone sodium succinate equivalent to 40 mg methylprednisolone; also 1.6 mg monobasic sodium phosphate anhydrous; 17.46 mg dibasic sodium phosphate dried and 25 mg lactose hydrous; and benzyl alcohol. 125 mg (Single - Dose Vial) Each 2 mL (when mixed as directed) contains methylprednisolone sodium succinate equivalent to 125 mg methylprednisolone; also 1.6 mg monobasic sodium phosphate anhydrous; and 17.4 mg dibasic sodium phosphate dried; and benzyl alcohol. 1 g (Multiple Dose Vial ) Each 16 mL (when mixed as directed) contains methylprednisolone sodium succinate equivalent to 1 gram methylprednisolone; also 12.8 mg monobasic sodium phosphate anhydrous; and 139.2 mg dibasic sodium phosphate dried; and benzyl alcohol. IMPORTANT - Use only Bacteriostatic Water For Injection with Benzyl Alcohol when reconstituting Methylprednisolone Sodium Succinate for Injection, USP. Use within 48 hours after mixing. When necessary, the pH of each formula was adjusted with sodium hydroxide so that the pH of the reconstituted solution is within the USP specified range of 7 to 8 and the tonicities are, for the 40 mg per mL solution, 0.50 osmolar; for the 125 mg per 2 mL solution, 0.40 osmolar; for the 1 g per 16 mL solution is 0.40 osmolar. (Isotonic saline = 0.28 osmolar). Structural Formula
