High doses of corticosteroids can cause cushing’s syndrome-with moon face, striae, and acne; it is usually reversible on withdrawal of treatment. In children, administration of corticosteroids may result in suppression of growth.
Warnings & Precautions
Particular care is required when considering the use of systemic corticosteroids in patients with recent myocardial infarction, hypothyroidism, osteoporosis, hypertension or congestive heart failure, diabetes mellitus, history of active tuberculosis, glaucoma (or a family history of glaucoma), previous corticosteroid-induced myopathy, liver failure, renal insufficiency, epilepsy and peptic ulcer.
Pharmacology & Mechanism of Action
Corticosteroids bind to the glucocorticoid receptor, inhibiting pro-inflammatory signals, and promoting anti-inflammatory signals. Betamethasone phosphate has a short duration of action as it is rapidly hydrolyzed to betamethasone. Corticosteroids have a wide therapeutic window as patients may require doses that are multiples of what the body naturally produces. Patients taking corticosteroids should be counselled regarding the risk of hypothalamic-pituitary-adrenal axis suppression and increased susceptibility to infections.
