Study Notes
Glucocorticoids
- Glucocorticoids, such as hydrocortisone and prednisone, have powerful effects on the body.
- They work by altering receptors, impacting gene expression.
- This leads to reduced inflammation suppression of the immune response, and regulation of metabolism.
Mineralocorticoids
- Mineralocorticoids, like fludrocortisone, primarily affect the kidneys.
- They act on mineralocorticoid receptors to increase sodium and water retention.
- They also promote potassium excretion.
Adrenal Androgens
- DHEA is an adrenal androgen.
- It's a precursor to sex hormones.
- It also has modest androgenic properties.
ACTH
- Cosyntropin is a synthetic form of ACTH.
- It stimulates the adrenal cortex to produce cortisol.
Corticosteroid Inhibitors
- Metyrapone inhibits enzymes in adrenal steroidogenesis.
- This use is for managing Cushing syndrome and adrenal tumours.
Aldosterone Antagonists
- Spironolactone blocks aldosterone receptors.
- This reduces sodium and water retention, aiding in blood pressure control.
