Fludrocortisone (Florinef) Pharmacology

On this podcast episode, I cover fludrocortisone. Fludrocortisone is a synthetic corticosteroid with potent mineralocorticoid activity and minimal glucocorticoid effects. It works primarily by promoting sodium reabsorption and potassium excretion in the distal renal tubules, leading to increased water retention and expansion of extracellular fluid volume. This pharmacologic action helps maintain blood pressure and electrolyte balance. Fludrocortisone is most commonly indicated for the treatment of adrenocortical insufficiency, such as Addison’s disease, and for managing orthostatic hypotension by enhancing vascular tone and volume status. Adverse effects are typically related to its mineralocorticoid potency and may include hypertension, edema, hypokalemia, and weight gain. Long-term use can also lead to complications such as heart failure exacerbation, osteoporosis, and mood changes. Because of its sodium-retaining effects, careful monitoring of blood pressure, electrolytes, and signs of fluid overload is recommended during therapy.
