LUSEDRA vs TIOTROPIUM BROMIDE
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.
Tiotropium bromide is a long-acting, competitive, and reversible muscarinic receptor antagonist (anticholinergic). It binds preferentially to M3 receptors in the smooth muscle of the bronchi, inhibiting acetylcholine-mediated bronchoconstriction and mucus secretion, leading to prolonged bronchodilation.
5 mg orally once daily.
Inhalation (oral): 18 mcg once daily via HandiHaler; or 2.5 mcg (2 puffs) once daily via Respimat inhaler.

8-12 hours (terminal, prolonged in renal impairment; dose adjustment needed if CrCl <30 mL/min).
Terminal elimination half-life: 5–6 days (inhalation). Longer half-life allows once-daily dosing. Steady-state reached in 2–3 weeks.
Primarily renal (70-80% as unchanged drug); 20-30% via biliary/fecal.
Primarily renal: 14% of dose excreted unchanged in urine; remainder as inactive metabolites via biliary/fecal (70%) and renal (30% total).
