Mineralocorticoid agonist
Mineralocorticoid receptor agonist
- ↑ renal sodium/water retention and potassium excretion → ↑ volume and BP
- Exploited therapeutically in orthostatic hypotension and adrenal insufficiency
- Sodium retention and potassium loss
- Fludrocortisone for adrenal insufficiency and orthostatic hypotension
Drugs with this mechanism (4)
- Aldosterone — Endogenous mineralocorticoid driving sodium retention and potassium loss.
- Fludrocortisone — Potent mineralocorticoid for adrenal insufficiency and orthostatic hypotension.
- Hydrocortisone — Cortisol given as a drug; physiologic replacement and topical steroid.
