CLINICAL PHARMACOLOGY
Glucocorticoids, naturally occurring and synthetic, are adrenocortical
steroids that are readily absorbed
from the gastrointestinal tract. Glucocorticoids cause varied
metabolic effects. In addition, they modify
the body’s immune responses to diverse stimuli. Naturally occurring
glucocorticoids (hydrocortisone
and cortisone), which also have sodium-retaining properties, are used
as replacement therapy in
adrenocortical deficiency states. Their synthetic analogs including
dexamethasone are primarily used
for their anti-inflammatory effects in disorders of many organ
systems.
At equipotent anti-inflammatory doses, dexamethasone almost completely
lacks the sodium-retaining
property of hydrocortisone and closely related derivatives of
hydrocortisone.
