Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Tolterodine is a competitive muscarinic receptor antagonist. It blocks acetylcholine binding at muscarinic receptors (M1–M5), reducing detrusor muscle contraction and bladder pressure, thereby increasing bladder capacity and decreasing urinary frequency.
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.
4 mg orally once daily; may be reduced to 2 mg once daily based on tolerability.
5 mg orally once daily.

Terminal elimination half-life is approximately 7 hours (range 5-10 hours) for the extended-release formulation, allowing once-daily dosing.
8-12 hours (terminal, prolonged in renal impairment; dose adjustment needed if CrCl <30 mL/min).
Approximately 77% eliminated in urine (primarily as metabolites, <1% unchanged) and 17% in feces.
Primarily renal (70-80% as unchanged drug); 20-30% via biliary/fecal.
