Precautions

Patient w/ heart failure, HTN, DM, GI disease (e.g. diverticulitis, intestinal anastomoses, peptic ulcer, ulcerative colitis), multiple sclerosis, myasthenia gravis, acute MI, cataracts, glaucoma, osteoporosis, history of seizure disorder, thyroid disease. Avoid abrupt withdrawal. Renal and hepatic impairment (including cirrhosis). Childn. Pregnancy and lactation. Monitoring Parameters Monitor BP, blood glucose, electrolytes, growth in childn. Lactation: Drug enters milk; use with caution

Pregnancy-Lactation

Pregnancy category: C Lactation: Drug enters milk; use with caution

Interactions

Decreases effect of anticholinesterases in myasthenia gravis. May decrease the hypoglycaemic effects of antidiabetic agents. Decreases serum concentrations of salicylates. Increased hypokalemic effects of potassium-depleting diuretics (thiazides or furosemide), amphotericin B, bronchodilator therapy with xanthines or beta2 agonists. Increase incidence of GI bleeding and ulceration with NSAIDs. May increase the anticoagulant effects of warfarin. Decreased levels/effects with CYP3A4 inducers (aminoglutethimide, carbamazepine, nafcillin, nevirapine, phenobarbital, phenytoin, and rifamycins). Increased levels/effects with CYP3A4 inhibitors (azole antifungals, clarithromycin, diclofenac, doxycycline, erythromycin, imatinib, isoniazid, nefazodone, nicardipine, propofol, protease inhibitors, quinidine, telithromycin, and verapamil). May decrease the effects of vaccines (dead organism) or increase the risk of vaccinal infection (live organism). Antacids and bile sequestrants may decrease the absorption of corticosteroids, separate admin by 2 hr. Increased risk of myopathy with neuromuscular-blocking agents, tendinopathies with fluoroquinolones.

Ophthalmic Exophthalmoses, glaucoma, increased intraocular pressure, posterior subcapsular cataracts.

Mechanism of Action

Methylprednisolone is a synthetic corticosteroid with mainly glucocorticoid activity and minimal mineralocorticoid properties. It decreases inflammation by suppression of migration of polymorphonuclear leukocytes and reversal of increased capillary permeability.
