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.

Systemic exposure to Dexamethasone reflects Consistent 67%–79% gastrointestinal absorption profile for Dexamethasone absorption kinetics and systemic clearance of dexamethasone integrates hepatic phase ii conjugation with renal filtration, sustaining receptor engagement across a Elimination kinetics span 5 to 18 hours per Dexamethasone clinical pharmacology half-life window (cmax attained 2–3 hours post-administration of dexamethasone response profile).
