WebFeb 2, 2024 · Cotinine is a metabolite of nicotine produced when nicotine is broken down in the body, primarily by the lungs, liver, and kidneys. It remains in the body longer (up to a few days) than nicotine, so it is a more reliable test to detect and measure nicotine exposure.

WebMay 11, 2024 · The median level of cotinine measured in blood serum of nonsmoking women of child-bearing age dropped from 0.21 ng/mL in 1988–1991 to 0.02 ng/mL in 2024–2024, a decrease of 90%. This decreasing trend was statistically significant. Cotinine values for women at the 95th percentile decreased by 46% from 1988–1991 to 2024–2024.
WebCotinine is the major metabolite of nicotine. In the liver, nicotine is rapidly metabolized to cotinine (70–80%) by CYP2A6 and to nornicotine (5%) by CYP2A6 and CYP2B6. With a half-life about 10-fold longer than that of nicotine (15–19 h for cotinine versus 2–3 h for nicotine), cotinine induces plasma concentrations of 1–3 μM in smokers.
