Nicotine is also metabolized in the kidneys and lungs. It identified more than 20 metabolites of nicotine, which are inferior to him in activity.

Communication nicotine blood plasma is less than 5%. Therefore disturbances nicotine binding while the use of other drugs or changes in the concentration of plasma proteins in various diseases should not have a significant effect on the kinetics of nicotine. The primary metabolite of nicotine in plasma - cotinine - has a T1 / 2 of 15-20 hours and its concentration exceeds that of nicotine by 10 times. Urine cotinine derived mainly (15% of the dose) and trans-3-hydroxy-cotinine (45% of dose). From 10 to 30% of the dose of nicotine is excreted in the urine in unchanged form.

The progressive deterioration of renal function is accompanied by a reduction in total clearance of nicotine. It does not change the pharmacokinetics in patients with cirrhosis of the liver with slightly pronounced liver function impairment (5 points on a scale Child-Pugh) and reduced in patients with liver cirrhosis with moderate hepatic dysfunction (7 points on a scale Child-Pugh). Smokers with concomitant chronic renal failure treated with hemodialysis, marked increase in nicotine concentration in the blood plasma. In elderly patients, there was a slight reduction in total clearance of nicotine, that does not require dose adjustment.
