Methylprednisolone
Methylprednisolone (Depo-Medrol, Medrol, Solu-Medrol) is a synthetic glucocorticoid, primarily prescribed for its anti-inflammatory and immunosuppressive effects. It is either used at low doses for chronic illnesses or used at high doses during acute flares. Methylprednisolone and its derivatives can be administered orally or parenterally.
Regardless of the route of administration, methylprednisolone integrates systemically as exhibited by its effectiveness to quickly reduce inflammation during acute flares. It is associated with many adverse reactions that require tapering off the drug as soon as the disease is under control. Serious side effects include iatrogenic Cushing's syndrome, hypertension, osteoporosis, diabetes, infection, psychosis, and skin atrophy.
Chemically, methylprednisolone is a synthetic pregnane steroid hormone derived from hydrocortisone and prednisolone. It belongs to a class of synthetic glucocorticoids and more generally, corticosteroids. It acts as a mineralocorticoid and glucocorticoid receptor agonist. In comparison to other exogenous glucocorticoids, methylprednisolone has a higher affinity to glucocorticoid receptors than to mineralocorticoid receptors.
Glucocorticoid's name was derived after the discovery of their involvement in regulating carbohydrate metabolism. The cellular functions of glucocorticoids, such as methylprednisolone, are now understood to regulate homeostasis, metabolism, development, cognition, and inflammation. They play a critical role in adapting and responding to environmental, physical, and emotional stress.
Methylprednisolone was first synthesized and manufactured by The Upjohn Company (now Viatris) and FDA approved in the United States in October 1957. In 2023, it was the 135th most commonly prescribed medication in the United States, with more than 4 million prescriptions. It is on the World Health Organization's List of Essential Medicines.
The primary use of methylprednisolone is to suppress inflammatory and immune responses. Methylprednisolone achieves this primarily by regulating the number and function of leukocytes, cytokines, and chemokines. Its widespread inflammatory control is conducive in use across multiple disorders regardless of pathology. Methylprednisolone is commonly prescribed as short-term therapy for acute flares, as seen with acute gouty arthritis. It can be prescribed during on-going therapy in lower doses contingent upon monitorization of adverse effects. Dosage strength and formulation are optimized per medical use.
In 2001–2002, 11.4% of patients diagnosed with asthma and seen at an outpatient visit were prescribed oral corticosteroids as a long-term control therapy. The National Asthma Education and Prevention Program (NAEPP) indicates systemic methylprednisolone in both short and long-term therapies to quickly control and to suppress persistent asthma, respectively. For exacerbations that result in a visit to the Emergency Department (ED), oral methylprednisolone is preferred over intravenous administration, unless there are issues with adherence or vomiting. Oral methylprednisolone is less invasive and studies have shown that equivalent efficacy compared to intravenous methylprednisolone. Dosage above 60–80 mg/day or 2 mg/kg/day is not recommended as it has not been shown to alter pulmonary function, rate of admission, or length of stay in the hospital compared to lower doses. Following ED discharge, it is advised to prescribe a five-day course of methylprednisolone to decrease the probability of relapse or withdrawal symptoms.
Methylprednisolone is used to treat several rheumatic diseases, such as Systemic Lupus Erythematosus (SLE) and Rheumatoid Arthritis (RA). Methylprednisolone dosage and administration for these diseases is highly variable due to varied pathophysiology between the diseases and within patients diagnosed with a given disease. In Lupus Nephritis, a common manifestation of SLE, patients are often prescribed methylprednisolone concomitantly with immunosuppressants. Severe manifestations are often treated with Cyclophosphamide or Rituximab and three doses of methylprednisolone IV-pulse treatment (as recommended by ACR guidelines) before switching to oral prednisolone and azathioprine for maintenance.
