DEXONE 1.5 vs EXSERVAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist that suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
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.
1.5 mg orally once daily
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 approximately 3-4 hours (dexamethasone), with clinical effects persisting 36-54 hours due to glucocorticoid receptor-mediated actions.
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 (primarily as metabolites, ~60%), biliary/fecal (~30%), with <5% excreted unchanged.
Primarily renal excretion as unchanged drug: 80% excreted unchanged in urine; approximately 20% as metabolites; biliary/fecal <5%.
