Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lithium modulates neurotransmitter activity in the central nervous system, including inhibition of inositol monophosphatase, leading to reduced phosphoinositide signaling; alters G-protein coupled receptor signaling; and inhibits glycogen synthase kinase-3 (GSK-3). It also affects ion transport, including sodium and potassium, and stabilizes neuronal excitability.
Lithium modulates neurotransmitter receptors, second messenger systems, and ion transport pathways; it inhibits inositol monophosphatase, leading to reduced inositol triphosphate and altered neuronal signaling; also affects glycogen synthase kinase-3 (GSK-3) activity and enhances neuroprotective pathways.
300-600 mg orally 2-3 times daily for acute mania; 600-1200 mg/day in divided doses for maintenance. Titrate to serum lithium level 0.8-1.2 mEq/L (acute) or 0.6-1.2 mEq/L (maintenance).
300-600 mg orally 2-3 times daily, titrated to serum lithium levels of 0.6-1.2 mEq/L.

Terminal elimination half-life 18-36 hours in young adults, up to 48-72 hours in elderly or with renal impairment; steady state reached in 5-7 days.
18-24 hours (terminal); prolonged in elderly, renal impairment, or dehydration; shorter in younger patients (12-14 hours); requires monitoring for narrow therapeutic index
Primarily renal excretion (>95% as unchanged lithium); less than 5% excreted in feces via bile.
Renal: >95% as unchanged drug; <1% fecal via bile; minor sweat/saliva
