酢酸メチルプレドニゾロン, 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.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.
Methylprednisolone acetate was previously suspended with polyethylene glycol but is no longer formulated with this excipient due to concerns about possible toxicity.Depo methylprednisolone acetate is a depot injection and is absorbed slowly with a duration of weeks to months with a single intramuscular injection.
Methylprednisolone is typically used for its anti-inflammatory effects. Common uses include arthritis therapy and short-term treatment of bronchial inflammation or acute bronchitis due to various respiratory diseases. Methylprednisolon is used both in the treatment of acute periods and long-term management of autoimmune diseases, most notably systemic lupus erythematosus.
