Study Notes
Adrenal Gland Function
-
The adrenal gland is an endocrine gland with different zones in the cortex that produce different steroids.
-
The hypothalamic-pituitary system controls hydrocortisone secretion through corticotropin releasing factor (CRF) and adrenocorticotropic hormone (ACTH).
-
Aldosterone secretion is primarily regulated by the renin-angiotensin system.
Addison's Disease and Pharmacotherapy
-
If the adrenal cortex fails (Addison's disease), replacement therapy with adrenocortical steroids is possible.
-
The primary medical use of adrenocortical steroids is for their anti-inflammatory and immunosuppressive effects.
-
These effects are seen only when the drug doses are much higher than needed for normal hormone replacement.
Metabolic Effects
-
Adrenocortical steroids have various metabolic effects that are crucial for normal body function.
-
However, at high doses (used for treatment), these can become adverse effects.
