Prednisone affects hormone levels in the body which is made up in part by the endocrine system housing the adrenal glands. Adrenal suppression, which is the inability to produce adequate amounts of the bodies natural steroid hormones. This helps in the production aldosterone which regulates sodium conservation, potassium secretion, and water retention. The effects on the adrenal function is very minor.
suppression
The disease is called as 'Addison's disease'. In developing countries, you get this disease very commonly, as a result of injudicious use of corticosteroids by quacks, leading to suppression of hypothalamo-pituitory-adrenal axis.
The central portion of the adrenal gland is known as the adrenal medulla. The function of the adrenal medulla is to secrete epinephrine into the body.
Evocative means to cause a specific response (evoke); it's used to describe various tests intended to cause production of hormones or other secretions. Suppression agents do the opposite (or suppress) the produciton of hormones or other secretions. These types of lab tests are used when a physician suspects that the patient is suffering from adrenal gland insufficiency.
The adrenal cortex, where aldosterone is produced, is part of the adrenal gland.
