CYP2A6 Polymorphisms May Strengthen Individualized Treatment for Nicotine Dependence
Each CYP2A6 gene variant metabolizes nicotine differently depending on its enzymatic activities. The normal nicotine metabolizer CYP2A6(*)1A is associated with high scores of nicotine dependence (5-10) on the Fagerström Test for Nicotine Dependence (FTND) scale because it encodes for enzymes that catalyze nicotine 100%. Slow nicotine metabolizers (i.e., CYP2A6(*)1H, CYP2A6(*)4A, CYP2A6(*)9, and...

متن کاملCYP2A6 gene polymorphisms impact to nicotine metabolism
Nicotine is a major addictive compound in tobacco cigarette smoke. After being absorbed by the lung nicotine is rapidly metabolized and mainly inactivated to cotinine by hepatic cytochrome P450 2A6 (CYP2A6) enzyme. Genetic polymorphisms in CYP2A6 may play a role in smoking behavior and nicotine dependence. CYP2A6*1A is the wild type of the CYP2A6 gene which is associated with normal or extensiv...
متن کاملGenetic polymorphisms in the cytochrome P450 2A6 (CYP2A6) gene: implications for interindividual differences in nicotine metabolism.
During the last couple of years, cytochrome P450 2A6 (CYP2A6; coumarin 7-hydroxylase) has received a lot of attention because it has been shown that it is the principle human nicotine C-oxidase. This enzyme also activates a number of structurally unrelated precarcinogens including many nitrosamines and aflatoxin B1, and metabolizes certain clinically used drugs. There is a pronounced interindiv...
متن کاملAre differences in guidelines for the treatment of nicotine dependence and non-nicotine dependence justified?
Despite the many similarities between nicotine dependence and other drug dependences, national guidelines for their treatment differ in several respects. The recent national guideline for the treatment of nicotine dependence has (i) less emphasis on detailed assessment; (ii) less emphasis on treatment of psychiatric comorbidity; (iii) less acceptance of reduction of use as an initial treatment ...
