Methylprednisolone acetate

Methylprednisolone acetate, sold under the brand names Depo-Medrol among others, is a synthetic glucocorticoid corticosteroid and a corticosteroid ester—specifically the C21 acetate ester of methylprednisolone—which is used in clinical and veterinary medicine.[1][2][3][4][5][6][7] It has been formulated as an aqueous suspension for intramuscular, intra-articular, soft tissue, and intralesional injection alone and in combination with lidocaine, a local anesthetic.[1][4][5] Methylprednisolone acetate was previously suspended with polyethylene glycol but is no longer formulated with this excipient due to concerns about possible toxicity.[6][8] Depot methylprednisolone acetate is a depot injection and is absorbed slowly with a duration of weeks to months with a single intramuscular injection.[5]
