LUSEDRA vs SCOPOLAMINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
LUSEDRA (valbenazine) is a selective vesicular monoamine transporter 2 (VMAT2) inhibitor. It reduces presynaptic dopamine release by inhibiting VMAT2, thereby reducing dopamine neurotransmission in the striatum.
Scopolamine is a competitive antagonist of muscarinic acetylcholine receptors (M1, M2, M3, M4, M5), blocking the action of acetylcholine at these receptors in the central nervous system and periphery.
5 mg orally once daily.
1.5 mg transdermal patch applied to postauricular skin every 72 hours; for prevention of motion sickness, apply 4-5 hours before exposure. Alternatively, 0.3-0.65 mg intramuscularly or intravenously every 6-8 hours as needed; or 0.4-0.8 mg subcutaneously. Oral dose: 0.4-0.8 mg every 6-8 hours as needed.

8-12 hours (terminal, prolonged in renal impairment; dose adjustment needed if CrCl <30 mL/min).
Terminal elimination half-life is approximately 2–4 hours in adults; in elderly or hepatic impairment, half-life may be prolonged.
Primarily renal (70-80% as unchanged drug); 20-30% via biliary/fecal.
Renal excretion of unchanged drug and metabolites accounts for approximately 50% of elimination; biliary/fecal excretion accounts for the remainder.
