CORTICOSTEROIDS Flashcards
What should be considered when starting oral corticosteroids?
- Age: children and older adults are more susceptible to adverse effects
- Medical history: Contraindicated with untreated systemic infection. Use cautiously in patients with other conditions
- Medication= check for interactions
- Immunisation= If patient is not up to date with vaccines, they need this before treatment
How are corticosteroids compared?
Potencies are compared by their glucocorticoid effects
Note you need both glucocorticoid and mineralocorticoid activity for benefit
What are mineralocorticoids
Class of corticosteroids
Produced in the adrenal cortex
Regulate sodium reabsorption and potassium excretion
Which corticosteroids are short acting?
Cortisone
Hydrocortisone
Which corticosteroids are intermediate acting?
Prednisolone
Prednisone
Methylprednisolone
Which corticosteroids are long acting?
Betamethasone
Dexamethasone
Why are Prednisolone and Prednisone used for long term disease?
Both drugs are glucocorticoids, mimicking cortisol to regulate inflammation and immune responses.
Long half life - suitable for daily dosing
What are glucocorticoids ?
Class of corticosteroids
Secreted by the adrenal gland
CORTISOL is most important example= regulates immune system and regulates cellular metabolism
What can high levels of cortisol cause
Insulin resistance and production of new glucose
When should a corticosteroid dose be given (Preferably)
Dose in the MORNING
Minimises suppressive action on cortisol secretion
Give some long term risks of corticosteroid therapy
HYPERTENSION due to fluid retention
ADRENAL SUPPRESSION
ADRENAL INSUFFICIENCY
INCREASED SUSCEPTIBILITY TO INFECTIONS: immunosuppression
PSYCHIATRIC RISKS - Depression, suicidal thoughts
