Quá liều
Symptoms: Nausea, vomiting, hypoglycaemia, Na and water retention, and occasional gastrointestinal bleeding. Management: Symptomatic and supportive treatment. May prevent gastrointestinal bleeding by giving 200-400 mg IV cimetidine 6 hourly or 50 mg IV ranitidine 6 hourly.
Tương tác
Effects may be reduced by barbiturates, phenytoin, rifampicin and ephedrine due to enhanced metabolism. May antagonise the hypotensive and hypoglycaemic effects of antihypertensives and oral antidiabetics, respectively. May increase risk of hypokalaemia with K-depleting diuretics (e.g. thiazides), furosemide, carbenoxolone, amphotericin B. May enhance or reduce response to anticoagulants. May increase the serum levels and risk of toxicity of salicylates if cortisone is withdrawn. Metabolism may be reduced by oestrogens. May increase risk of methotrexate toxicity. Potentially Fatal: May diminish the therapeutic effects of live vaccines.
Tương tác với thức ăn
Increased risk of gastrointestinal ulceration or haemorrhage with alcohol.

Wheal and flare reactions to skin test antigens may be suppressed. May cause false-negative result in nitroblue-tetrazolinium tests for bacterial infections.
Tác dụng
Description: Mechanism of Action: Cortisone, a corticosteroid secreted by the adrenal cortex, exhibits glucocorticoid and some mineralocorticoid activity. It decreases inflammation by inhibiting the migration of polymorphonuclear leukocytes and reversal of increased capillary permeability. Pharmacokinetics: Absorption: Readily absorbed from the gastrointestinal tract. Bioavailability: 43.7% (range: 20-95%). Time to peak plasma concentration: Approx 2 hours. Distribution: Crosses the placenta. Distributed into the skin, muscles, liver, intestines and kidneys. Plasma protein binding: >90%. Metabolism: Rapidly metabolised in the liver via reduction by 11-β-hydroxy-dehydrogenase to its active metabolite, hydrocortisone (cortisol). Excretion: Via urine and faeces. Elimination half-life: Approx 0.5 hours.
