DEFLAZACORT vs HALDRONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Deflazacort is a glucocorticoid prodrug that is metabolized to its active form, 21-desacetyldeflazacort. It binds to glucocorticoid receptors, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating cytokine production.
Glucocorticoid receptor agonist; suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene transcription.
6-90 mg orally once daily; initial dose typically 6-30 mg/day, maintenance as lowest effective dose; taper gradually upon discontinuation.
Oral: Initial dose 50-100 mg twice daily; maintenance 25-50 mg twice daily. Maximum 200 mg/day.

Terminal half-life of the active metabolite Δ6-deflazacort is 1.1–1.9 hours; parent drug half-life is approximately 1–2 hours. Clinical glucocorticoid effect persists for 12–24 hours due to receptor binding.
Terminal elimination half-life: 2.6-3.8 hours. Clinical context: Short half-life requires multiple daily dosing; no significant accumulation with regular dosing.
Renal (approximately 70% as metabolites, <5% unchanged); biliary/fecal (approximately 30%)
Renal: 20-30% as unchanged drug; biliary/fecal: 70-80% as metabolites and unchanged drug.
