SYLEVIA vs TOVALT ODT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexmedetomidine is a selective alpha-2 adrenergic receptor agonist, producing sedation, analgesia, and anxiolysis by reducing norepinephrine release in the locus coeruleus.
Tovalt ODT (selegiline) is a selective, irreversible inhibitor of monoamine oxidase type B (MAO-B). At therapeutic doses, it inhibits MAO-B more selectively than MAO-A, leading to increased levels of dopamine in the brain.
Adults: 400 mg orally once daily.
20 mg sublingually as needed for BTP, with a minimum interval of 2 hours between doses; maximum 4 doses per day.

Terminal elimination half-life is 27-33 hours in adults with normal renal function. Clinical context: Requires dose adjustment in renal impairment (creatinine clearance <30 mL/min reduces clearance by 50%).
Terminal elimination half-life approximately 40–60 hours after multiple dosing; clinical context: reaches steady-state after 2–3 weeks.
Renal excretion accounts for approximately 70% of the administered dose as unchanged drug, with biliary/fecal elimination contributing 20-30% (primarily as metabolites).
Primarily hepatic metabolism; 70–80% as inactive metabolites in urine, <5% unchanged in urine, 20–30% fecal.
