primary metabolic transformation occurs in intestinal microbiota Bacterial trimethylamine (TMA) formation from excess dietary L-carnitine, subsequently oxidized to TMAO in liver Renal excretion: primary elimination route with efficient tubular reabsorption via OCTN2 Urinary excretion increases proportionally with plasma concentrations above renal threshold Plasma half-life: ~15 hours with normal renal function Elimination half-life extended in renal insufficiency These pharmacokinetic characteristics inform research protocol design, particularly regarding administration regimens, tissue sampling timepoints, and expected tissue concentrations in experimental models
Its central mechanism means a longer, more gradual onset is part of its design
