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 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), and the molecular weight is 496.53. The structural formula is represented below: Methylprednisolone Sodium Succinate, USP 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, USP, is available in two strengths and packages for intravenous or intramuscular administration: 500 mg (Multiple Use Vial) —Each 8 mL (when mixed) contains Methylprednisolone Sodium Succinate, USP equivalent to 500 mg methylprednisolone; also 6.4 mg monobasic sodium phosphate anhydrous; and 69.6 mg dibasic sodium phosphate dried. 1 gram (Multiple Use Vial) —Each 16 mL (when mixed) contains Methylprednisolone Sodium Succinate, USP equivalent to 1 gram methylprednisolone; also 12.8 mg monobasic sodium phosphate anhydrous; and 139.2 mg dibasic sodium phosphate dried. 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 500 mg per 8 mL and 1 gram per 16 mL solutions, 0.33 osmolar.
