WebMay 5, 2014 · It is possible to relate the half-peak potential (E p/2, where the current is half of the peak current) to the polarographic half-wave potential, E 1/2 E p/2 = E 1/2 ± 29mV/n (8) (The sign is positive for a reduction process.) For multielectron-transfer (reversible) processes, the cyclic voltammogram consists of several ... WebFeb 25, 2024 · Elimination Half-life: The half-life of warfarin is generally 20 to 60 hours (mean: 40 hours). However, it is highly variable among individuals. Time to peak (plasma concentration): approximately 4 hours. Excretion: Warfarin is primarily eliminated as metabolites by glomerular filtration in the kidney (92% via urine).
