DEFLAZACORT vs EXSERVAN
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.
Exservan (riluzole) is a benzothiazole derivative that modulates glutamatergic neurotransmission. Its mechanism of action involves inhibition of glutamate release, inactivation of voltage-dependent sodium channels, and interference with neurotransmitter binding to excitatory amino acid receptors.
6-90 mg orally once daily; initial dose typically 6-30 mg/day, maintenance as lowest effective dose; taper gradually upon discontinuation.
Adults: 15 mg orally once daily in the morning; increase to 30 mg after 2 weeks if needed. Maximum 30 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 is approximately 3–4 hours in patients with normal renal function; prolonged in renal impairment (up to 8–10 hours in ESRD).
Renal (approximately 70% as metabolites, <5% unchanged); biliary/fecal (approximately 30%)
Primarily renal excretion as unchanged drug: 80% excreted unchanged in urine; approximately 20% as metabolites; biliary/fecal <5%.
