What is Methylprednisolone Acetate?
Treatment of a wide variety of diseases and conditions principally for glucocorticoid effects as an anti-inflammatory and immunosuppressant agent and for its effects on blood and lymphatic systems in the palliative treatment of various diseases.
Usually, inadequate alone for adrenocortical insufficiency because of minimal mineralocorticoid activity.
Adrenocortical Insufficiency
Corticosteroids are administered in physiologic dosages to replace deficient endogenous hormones in patients with adrenocortical insufficiency.
Because production of both mineralocorticoids and glucocorticoids is deficient in adrenocortical insufficiency, hydrocortisone or cortisone (in conjunction with liberal salt intake) usually is the corticosteroid of choice for replacement therapy.
If methylprednisolone is used, must also administer a mineralocorticoid (fludrocortisone), particularly in infants.
In suspected or known adrenal insufficiency, parenteral therapy may be used preoperatively or during serious trauma, illness, or shock unresponsive to conventional therapy.
In shock unresponsive to conventional therapy, IV therapy in conjunction with other therapy for shock is essential; hydrocortisone is preferred, but a synthetic glucocorticoid like methylprednisolone can be substituted.
Adrenogenital Syndrome
Lifelong glucocorticoid treatment of congenital adrenogenital syndrome.
In salt-losing forms, cortisone or hydrocortisone is preferred in conjunction with liberal salt intake; a mineralocorticoid may be necessary in conjunction through at least 5–7 years of age.
A glucocorticoid, usually alone, for long-term therapy after early childhood.
In hypertensive forms, a “short-acting” glucocorticoid with minimal mineralocorticoid activity (e.g., methylprednisolone, prednisone) is preferred; avoid long-acting glucocorticoids (e.g., dexamethasone) because of tendency toward overdosage and growth retardation.
Hypercalcemia
Treatment of hypercalcemia associated with malignancy.
Usually ameliorates hypercalcemia associated with bone involvement in multiple myeloma.
Most effective long-term treatment for hypercalcemia associated with breast cancer in postmenopausal women.
Efficacy varies in other malignancies.
Treatment of hypercalcemia associated with sarcoidosis.
Treatment of hypercalcemia associated with vitamin D intoxication.
Not effective for hypercalcemia caused by hyperparathyroidism.
Thyroiditis
Treatment of granulomatous (subacute, nonsuppurative) thyroiditis.
Anti-inflammatory actions relieves fever, acute thyroid pain, and swelling.
May reduce orbital edema in endocrine exophthalmos (thyroid ophthalmopathy).
Usually reserved for palliative therapy in severely ill patients unresponsive to salicylates and thyroid hormones.
Rheumatic Disorders and Collagen Diseases
Short-term palliative treatment of acute episodes or exacerbations and systemic complications of rheumatic disorders (e.g., rheumatoid arthritis, juvenile arthritis, psoriatic arthritis, acute gouty arthritis, posttraumatic osteoarthritis, synovitis of osteoarthritis, epicondylitis, acute nonspecific tenosynovitis, ankylosing spondylitis, Reiter syndrome, rheumatic fever [especially with carditis]) and collagen diseases (e.g., acute rheumatic carditis, systemic lupus erythematosus, dermatomyositis [polymyositis], polyarteritis nodosa, vasculitis) refractory to more conservative measures.
Relieves inflammation and suppresses symptoms but not disease progression.
Rarely indicated as maintenance therapy.
May be used as maintenance therapy (e.g., in rheumatoid arthritis, acute gouty arthritis, systemic lupus erythematosus, acute rheumatic carditis) as part of a total treatment program in selected patients when more conservative therapies have proven ineffective.
Glucocorticoid withdrawal is extremely difficult if used for maintenance; relapse and recurrence usually occur with drug discontinuance.
Local injection can provide dramatic relief initially for articular manifestations of rheumatic disorders (e.g., rheumatoid arthritis) that involve only a few persistently inflamed joints or for inflammation of tendons or bursae; inflammation tends to recur and sometimes is more intense after drug cessation.
Local injection used for the management of cystic tumors of an aponeurosis or tendon (ganglia).
Local injection can prevent invalidism by facilitating movement of joints that might otherwise become immobile.
Controls acute manifestations of rheumatic carditis more rapidly than salicylates and may be life-saving; cannot prevent valvular damage and no better than salicylates for long-term treatment.
Adjunctively for severe systemic complications of Wegener’s granulomatosis, but cytotoxic therapy is the treatment of choice.
Primary treatment to control symptoms and prevent severe, often life-threatening complications in patients with dermatomyositis and polymyositis, polyarteritis nodosa, relapsing polychondritis, polymyalgia rheumatica and giant-cell (temporal) arteritis, or mixed connective tissue disease syndrome. High dosage may be required for acute situations; after a response has been obtained, drug must often be continued for long periods at low dosage.
Polymyositis associated with malignancy and childhood dermatomyositis may not respond well.
Rarely indicated in psoriatic arthritis, diffuse scleroderma (progressive systemic sclerosis), acute and subacute bursitis, or osteoarthritis; risks outweigh benefits.
In osteoarthritis, intra-articular injections may be beneficial but should be limited in number as joint damage may occur.
Dermatologic Diseases
Treatment of pemphigus and pemphigoid, bullous dermatitis herpetiformis, severe erythema multiforme (Stevens-Johnson syndrome), exfoliative dermatitis, uncontrollable eczema, cutaneous sarcoidosis, mycosis fungoides, lichen planus, lichen simplex chronicus (neurodermatitis), severe psoriasis, and severe seborrheic dermatitis.
Usually reserved for acute exacerbations unresponsive to conservative therapy.
Early initiation of systemic glucocorticoid therapy may be life-saving in pemphigus vulgaris and pemphigoid, and high or massive doses may be required.
For control of severe or incapacitating allergic conditions (e.g., contact dermatitis, atopic dermatitis) intractable to adequate trials of conventional treatment.
Chronic skin disorders seldom an indication for systemic glucocorticoids.
Intralesional or sublesional injections occasionally indicated for localized chronic skin disorders, keloids, psoriatic plaques, alopecia areata, discoid lupus erythematosus, necrobiosis lipoidica diabeticorum, granuloma annulare unresponsive to topical therapy.
Rarely indicated for psoriasis; if used, exacerbation may occur when the drug is withdrawn or dosage is decreased.
Rarely indicated systemically for alopecia (areata, totalis, or universalis). May stimulate hair growth, but hair loss returns when the drug is discontinued.
Allergic Conditions
For control of severe or incapacitating allergic conditions intractable to adequate trials of conventional treatment and control of acute manifestations, including anaphylactic and anaphylactoid reactions, angioedema, acute noninfectious laryngeal edema, serum sickness, allergic symptoms of trichinosis, asthma, urticarial transfusion reactions, drug hypersensitivity reactions, and severe seasonal or perennial rhinitis.
Systemic therapy usually reserved for acute conditions and severe exacerbations.
For acute conditions, usually used in high dosage and with other therapies (e.g., antihistamines, sympathomimetics).
Reserve prolonged treatment of chronic allergic conditions for disabling conditions unresponsive to more conservative therapy and when risks of long-term glucocorticoid therapy are justified.
Ocular Disorders
To suppress a variety of allergic and nonpyogenic ocular inflammations.
To reduce scarring in ocular injuries.
For the treatment of severe acute and chronic allergic and inflammatory processes involving the eye and adnexa (e.g., allergic conjunctivitis, keratitis, allergic corneal marginal ulcers, herpes zoster ophthalmicus, iritis and iridocyclitis, chorioretinitis, diffuse posterior uveitis and choroiditis, anterior segment inflammation, optic neuritis, sympathetic ophthalmia, temporal arteritis).
Acute optic neuritis optimally treated with initial high-dose IV therapy followed by chronic oral therapy. Assists in recovery of vision and slows progression to clinically definite multiple sclerosis.
Less severe allergic and inflammatory allergic conditions of the eye are treated with topical (to the eye) corticosteroids.
Topically applied glucocorticoids appear to be as effective as systemic steroids for the treatment of most anterior ocular inflammations.
Systemically in stubborn cases of anterior segment eye disease and when deeper ocular structures are involved.
Asthma
Adjunctively for moderate to severe exacerbations of asthma and for maintenance in persistent asthma.
Systemically (oral or IV) for treatment of moderate to severe acute exacerbations of asthma (oral prednisone usually preferred); speeds resolution of airflow obstruction and reduces rate of relapse.
Because onset of effects is delayed, do not use alone for emergency treatment.
Early systemic glucocorticoid therapy particularly important for asthma exacerbations in infants and children.
In hospital management of an acute asthma exacerbation, may give systemic adjunctive glucocorticoids if response to oral inhalation therapy is not immediate, if oral corticosteroids were used as self-medication prior to hospitalization, or if the episode is severe.
For severe persistent asthma once initial control is achieved, high dosages of inhaled corticosteroids are preferable to oral glucocorticoids for maintenance because inhaled corticosteroids have fewer systemic effects.
Maintenance therapy with low doses of an orally inhaled corticosteroid is preferred treatment for adults and children with mild persistent asthma (i.e., patients with daytime symptoms of asthma more than twice weekly but less than once daily, and nocturnal symptoms of asthma more than twice per month).
Orally as an adjunct to other therapy to speed resolution of all but the mildest exacerbations of asthma when response to a short-acting inhaled β2-agonist is not prompt or sustained after 1 hour or in those who have a history of severe exacerbations.
Oral glucocorticoids with minimal mineralocorticoid activity and relatively short half-life (e.g., prednisone, prednisolone, methylprednisolone) are preferred.
COPD
For severe exacerbations of COPD, a short (e.g., 1–2 weeks) course of oral glucocorticoids can be added to existing therapy.
Effects in stable COPD are much less dramatic than in asthma, and role of glucocorticoids in the management of stable COPD is limited to very specific indications.
Croup
Adjunctive treatment of croup in pediatric patients.
Decreases edema in laryngeal mucosa.
Reduces need for hospitalization, shorter duration of hospitalization, and reduces need for subsequent interventions (e.g., epinephrine).
Sarcoidosis
Management of symptomatic sarcoidosis.
Systemic glucocorticoids are indicated for hypercalcemia; ocular, CNS, glandular, myocardial, or severe pulmonary involvement; or severe skin lesions unresponsive to intralesional injections of glucocorticoids.
Advanced Pulmonary and Extrapulmonary Tuberculosis
Systemically as adjunctive therapy with effective antimycobacterial agents (e.g., streptomycin, isoniazid) to suppress manifestations related to the host’s inflammatory response to the bacillus (Mycobacterium tuberculosis) and ameliorate complications in severe pulmonary or extrapulmonary tuberculosis.
Adjunctive glucocorticoid therapy may enhance short-term resolution of disease manifestations (e.g., clinical and radiographic abnormalities) in advanced pulmonary tuberculosis and also may reduce mortality associated with certain forms of extrapulmonary disease (e.g., meningitis, pericarditis).
Systemic adjunctive glucocorticoids may reduce sequelae (e.g., intellectual impairment) and/or improve survival in moderate to severe tuberculous meningitis; used in the treatment of tuberculous meningitis with subarachnoid block or impending block concurrently with appropriate antituberculous chemotherapy.
Systemic adjunctive glucocorticoid therapy rapidly reduces the size of pericardial effusions and the need for drainage procedures and decreases mortality (probably through control of hemodynamically threatening effusion) in acute tuberculous pericarditis.
Hastens the resolution of pain, dyspnea, and fever associated with tuberculous pleurisy.
Lipid Pneumonitis
Promotes the breakdown or dissolution of pulmonary lesions and eliminates sputum lipids in lipid pneumonitis.
Pneumocystis jiroveci Pneumonia
Systemic adjunctive glucocorticoids decrease the likelihood of deterioration of oxygenation, respiratory failure, and/or death in moderate to severe Pneumocystis jiroveci (formerly Pneumocystis carinii) pneumonia in AIDS.
Prevents early deterioration in oxygenation associated with antipneumocystis therapy; initiate adjunctive glucocorticoid therapy as early as possible in moderate to severe pneumocystis pneumonia.
Not known whether patients with mild pneumocystis pneumonia (arterial oxygen pressure >70 mm Hg or arterial-alveolar gradient <35 mm Hg on room air) will have clinically important benefit with adjunctive glucocorticoid therapy.
Oral prednisone or parenteral methylprednisolone generally is preferred.
Loeffler’s Syndrome
Symptomatic relief of acute manifestations of symptomatic Loeffler’s syndrome not manageable by other means.
Berylliosis
Symptomatic relief of acute manifestations of berylliosis.
Aspiration Pneumonitis
Symptomatic relief of acute manifestations of aspiration pneumonitis.
Anthrax
Adjunct to anti-infective therapy in the treatment of anthrax in an attempt to ameliorate toxin-mediated effects associated with Bacillus anthracis infections.
For cutaneous anthrax if there are signs of systemic involvement or extensive edema involving the neck and thoracic region, anthrax meningitis, and inhalational anthrax that occurs as the result of exposure to anthrax spores in the context of biologic warfare or bioterrorism if extensive edema, respiratory compromise, or meningitis is present.
Hematologic Disorders
Management of acquired (autoimmune) hemolytic anemia, pure red cell aplasia, idiopathic thrombocytopenic purpura (ITP), secondary thrombocytopenia, erythroblastopenia, or congenital (erythroid) hypoplastic anemia.
High or even massive dosages decrease bleeding tendencies and normalize blood counts; does not affect the course or duration of hematologic disorders.
Glucocorticoids, immune globulin IV (IGIV), or splenectomy are first-line therapies for moderate to severe ITP, depending on the extent of bleeding involved.
May not affect or prevent renal complications in Henoch-Schoenlein purpura.
Insufficient evidence of effectiveness in aplastic anemia in children, but widely used.
Shock
Although IV glucocorticoids may be life-saving in shock secondary to adrenocortical insufficiency (see Adrenocortical Insufficiency under Uses), the value of the drugs in the treatment of shock resulting from other causes is controversial.
Management of shock should be based on specific treatment of the primary cause and secondary abnormalities, and glucocorticoids, if used, should be regarded only as adjunctive supportive treatment.
Value in adjunctive treatment of septic shock is particularly controversial. Conflicting evidence regarding effects of high-dose regimens on morbidity and mortality in septic shock. In a clinical study, methylprednisolone was ineffective in the treatment of sepsis syndrome and septic shock, and may increase the risk of mortality in certain patients (i.e., patients with increased Scr or those who develop secondary infections after treatment).
Pericarditis
To reduce the pain, fever, and inflammation of pericarditis, including that associated with MI.
Glucocorticoids can provide effective symptomatic relief, but aspirin considered the treatment of choice for post-MI pericarditis because of greater evidence establishing benefit.
Important to distinguish between pain caused by pericarditis and that caused by ischemia since management will differ.
Consider possibility that cardiac rupture may account for recurrent pain since use of glucocorticoids may be a risk factor in its development.
Glucocorticoids may cause thinning of developing scar and myocardial rupture.
Management of tuberculous pericarditis. (See Advanced Pulmonary and Extrapulmonary Tuberculosis under Uses.)
GI Diseases
Short-term palliative therapy for acute exacerbations and systemic complications of ulcerative colitis, regional enteritis (Crohn’s disease), and celiac disease.
Do not use if a probability of impending perforation, abscess, or other pyogenic infection.
Rarely indicated for maintenance therapy in chronic GI diseases (e.g., ulcerative colitis, celiac disease) since does not prevent relapses and may produce severe adverse reactions with long-term administration.
Occasionally, low dosages, in conjunction with other supportive therapy, may be useful for disease unresponsive to the usual therapy indicated for chronic conditions.
Management of mildly to moderately active and moderately to severely active Crohn’s disease .
Parenteral glucocorticoids recommended for patients with severe fulminant Crohn’s disease. Once patients respond to parenteral therapy, they should gradually be switched to an equivalent regimen of an oral glucocorticoid.
Some experts state that glucocorticoids should not be used for the management of mildly to moderately active Crohn’s disease because of the high incidence of adverse effects and their use should be reserved for patients with moderately to severely active disease.
Glucocorticoids should not be used for maintenance therapy of chronic GI diseases (e.g., ulcerative colitis, Crohn’s disease) because they usually do not prevent relapses and the drugs may produce severe adverse effects with long-term administration.
Glucocorticoids have been used in the management of moderately to severely active Crohn’s disease and in mild esophageal or gastroduodenal Crohn’s disease in pediatric patients.
Neoplastic Diseases
Alone or as a component of various chemotherapeutic regimens in the palliative treatment of neoplastic diseases of the lymphatic system (e.g., leukemias and lymphomas in adults and acute leukemias in children).
Treatment of breast cancer; glucocorticoids alone not as effective as other agents (e.g., cytotoxic agents, hormones, antiestrogens) and should be reserved for unresponsive disease.
Glucocorticoids alone or as a component of various combination chemotherapeutic regimens for palliative treatment of advanced, symptomatic (i.e., painful) hormone-refractory prostate cancer.
Cancer Chemotherapy-induced Nausea and Vomiting
Prevention of nausea and vomiting associated with emetogenic cancer chemotherapy.
Cerebral Edema
To decrease cerebral edema associated with brain tumors and neurosurgery.
Cerebral edema associated with pseudotumor cerebri may also benefit, but efficacy of glucocorticoids is controversial and remains to be established.
Edema resulting from brain abscesses is less responsive than that resulting from brain tumors.
Pharmacologic management of cerebral edema is not a substitute for careful neurosurgical evaluation and definitive management such as neurosurgery or other specific therapy.
Head Injury
Efficacy of glucocorticoid therapy is not established in patients with head injury; such therapy can be detrimental and is associated with a substantial increase in risk of death. Use to improve outcome or reduce intracranial pressure not recommended in patients with head injury.
Cerebral Malaria
Glucocorticoids are not effective and can have detrimental effects in the management of cerebral malaria caused by Plasmodium falciparum; no longer recommended for this condition.
Acute Spinal Cord Injury
Some evidence indicates that large IV doses of glucocorticoids (i.e., methylprednisolone) can improve motor and sensory function in patients with acute spinal cord injury when treatment is initiated promptly following injury (within 8 hours). It is not known whether improvement in neurologic function with such therapy will routinely lead to specific improvements in disability.
Low Back Pain
Has been used epidurally (alone or combined with a local anesthetic and/or an opiate analgesic) for symptomatic relief of low back pain.
Although use remains controversial and convincing evidence of efficacy is lacking, most experts consider such therapy an option for short-term relief of acute, subacute, or chronic radicular pain in patients with low back pain and radiculopathy associated with disk disease or herniation or spinal stenosis when more conservative therapies (e.g., rest, analgesics, physical therapy) fail and as a means of potentially avoiding surgery. (See Nervous System Effects under Cautions.)
Limited evidence suggests that therapeutic facet joint and intradiscal glucocorticoid injections are minimally effective or ineffective in the treatment of low back pain, although facet joint injections may be useful in some patients with facet arthropathy. Inclusion of a glucocorticoid in trigger point injections does not appear to be beneficial.
Sacroiliac joint injections performed using fluoroscopic guidance may provide temporary pain relief in some patients when the principal source of spinal pain is the sacroiliac joint.
Oral glucocorticoids have been used; however, they do not appear to be effective and evidence supporting such use is lacking.
Bacterial Meningitis
Limited data in animals suggest that dexamethasone may be superior to methylprednisolone in reversing certain CSF abnormalities (e.g., intracranial hypertension, elevated lactate concentrations) associated with bacterial meningitis, and experience is insufficient to allow recommendation of glucocorticoids other than dexamethasone for adjunctive therapy in bacterial meningitis.
Short-term IV adjunctive therapy with dexamethasone is preferred.
Multiple Sclerosis
Glucocorticoids are drugs of choice for the management of acute relapses of multiple sclerosis and have replaced corticotropin as the therapy of choice because of a more rapid onset of action, more consistent effects, and fewer adverse effects.
Anti-inflammatory and immunomodulating effects accelerate neurologic recovery by restoring the blood-brain barrier, reducing edema, and possibly improving axonal conduction.
Shortens the duration of relapse and accelerates recovery; remains to be established whether the overall degree of recovery improves or the long-term course is altered.
Myasthenia Gravis
Management of myasthenia gravis, usually when there is an inadequate response to anticholinesterase therapy.
Parenterally for the treatment of myasthenic crisis.
Organ Transplants
In massive dosage, used concomitantly with other immunosuppressive drugs to prevent rejection of transplanted organs.
Incidence of secondary infections is high with immunosuppressive drugs; limit to clinicians experienced in their use.
Trichinosis
Treatment of trichinosis with neurologic or myocardial involvement.
Nephrotic Syndrome and Lupus Nephritis
Treatment of idiopathic nephrotic syndrome without uremia.
Can induce diuresis and remission of proteinuria in nephrotic syndrome secondary to lupus erythematosus or primary renal disease, especially when there is minimal renal histologic change.
Treatment of lupus nephritis.
Carpal Tunnel Syndrome
Local injection of glucocorticoids (e.g., methylprednisolone, betamethasone) into the tissue near the carpal tunnel has been used in a limited number of patients to relieve symptoms (e.g., pain, edema, sensory deficit) of carpal tunnel syndrome.
