Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Agonist at glucocorticoid receptors, leading to altered gene expression and suppression of inflammatory mediators.
Unknown. It is a purified fatty acid derivative that may modulate inflammatory responses.
0.5-24 mg/day oral, IV, IM in 2-4 divided doses; anti-inflammatory: 0.75-9 mg/day; multiple myeloma: 40 mg oral/IV once daily on days 1-4, 9-12, 17-20 every 28 days.
2.5 mg subcutaneously once daily.

Terminal elimination half-life is 6-8 hours; in moderate renal impairment (CrCl 30-50 mL/min) extends to 12-15 hours.
Primarily renal (65-80% as unchanged drug); minor biliary/fecal (<10%).
