SOLU-MEDROL 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-3,20dione,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 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.
SOLU-MEDROL is available in preservative and
preservative-free formulations:
