Adverse Reactions
Adrenal suppression, anaphylactoid reactions, immunosuppression, acute myopathy, Kaposi's sarcoma, psychiatric disturbances (e.g. depression, euphoria, insomnia, mood swings, personality changes), increased susceptibility and severity of infections, impaired healing, HTN, Na and fluid retention, CV collapse (high dose), peptic ulcer, cataract subcapsular, skin atrophy, acne, muscular weakness, growth retardation, decreased blood K; dermal/subdermal skin depression at inj site. Topical: Itching, burning erythema, vesiculation; rarely, folliculitis, hypertrichosis, perioral dermatitis, skin discolouration, allergic skin reactions.
Drug Interactions
Loss of corticosteroid-induced adrenal suppression w/ aminoglutethimide. Risk of hypokalaemia w/ K-depleting agents (e.g. amphotericin B, diuretics). Decreased clearance w/ macrolide antibiotics. May decrease serum levels of isoniazid. Increased clearance w/ cholestyramine. Risk of convulsions w/ ciclosporin. Increased risk of arrhythmias w/ digitalis glycosides. Decreased metabolism w/ oestrogens, including OCs. Enhanced metabolism w/ CYP3A4 inducers (e.g. rifampicin, barbiturates). Increased plasma concentrations w/ CYP3A4 inhibitors (e.g. ketoconazole, erythromycin). Risk of GI effects w/ aspirin or other NSAIDs. May increase the anticoagulant effect of warfarin. May reduce the therapeutic effect of antidiabetics.
Potentially Fatal: May diminish response to live or live, attenuated vaccines.
Lab Interference
May suppress reactions to skin test.
Action
Methylprednisolone binds to and activates intracellular glucocorticoid receptors. Activated glucocorticoid receptors bind to promoter regions of DNA (which may activate or suppress transcription) and activate transcription factors resulting in inactivation of genes through deacetylation of histones.
Onset: Peak effect: 1-2 hr (oral); 4-8 days (IM); 1 wk (intra-articular).
Duration: 30-36 hr (oral); 1-4 wk (IM); 1-5 wk (intra-articular).
Absorption: Rapidly absorbed (oral); absorbed from joints over a wk but is more slowly absorbed following deep IM inj (as acetate); rapidly absorbed after IM inj (Na succinate ester). Time to peak plasma concentration: 2 hr (Na succinate ester).
Distribution: Fairly rapidly distributed (oral). Crosses the placenta. Volume of distribution: 0.7-1.5 L/kg.
Excretion: Plasma half-life: ≥3.5 hr.
Storage
Intra-articular: Store between 20-25°C. Intralesional: Store between 20-25°C. Intramuscular: Store between 20-25°C. Intravenous: Store between 20-25°C. Oral: Store between 20-25°C. Topical/Cutaneous: Store between 20-25°C.
