December 25, 2017Replacement therapy
The adrenal cortex normally secretes hydrocortisone (cortisol) which has glucocorticoid activity and weak mineralocorticoid activity. It also secretes the mineralocorticoid aldosterone. In deficiency states, physiological replacement is best achieved with a combination of hydrocortisone and the mineralocorticoid fludrocortisone; hydrocortisone alone does not usually provide sufficient mineralocorticoid activity for complete replacement.
FLUDROCORTISONE ACETATE:
Indications: mineralocorticoid replacement in adrenocortical insufficiency. Adrenogenital Disorder, Primary Adrenocortical Insufficiency, Symptomatic Orthostatic Hypotension.
Contraindications: Chronic Heart Failure, Acute Tuberculosis, Cataracts, Diabetes Mellitus, Disease of Liver, Epilepsy, Glaucoma, Hypercortisolism, Hypertension, Hypokalemia, Hypothyroidism, Inactive Tuberculosis, Myasthenia Gravis, Osteoporosis, Peptic Ulcer, Peripheral Edema, Renal Disease.
Dose and Administration: 50–300 micrograms daily; child 5 micrograms/kg daily.
