Polycyclic aromatic hydrocarbons (PAHs) -- products of incomplete combustion -- are some of the major lung carcinogens found in tobacco … Tobacco smoke interacts with medications through pharmacokinetic (PK) and pharmacodynamic (PD) mechanisms. Drugs that are significantly metabolized by CYP1A2 (major substrates) are more likely to be impacted by changes in tobacco smoking compared with minor substrates. PURPOSE The mechanisms for drug interactions with smoking and clinically significant pharmacokinetic and pharmacodynamic drug interactions with smoking are reviewed. �ׯ����H���fN�r*Rh5�ӂ�����y�q�7�*g�=Q�B�L�`^H8zR��J( C�����n����w�n�v Zevin S, Benowitz NL. Tobacco smokers who take medications and hormones that are metabolized by CYP1A2 enzymes should be closely monitored because dosage adjustments may be necessary when they start or stop smoking cigarettes. Drug Interactions with Smoking Cessation Medications and Tobacco Smoke* Bupropion NRT Varenicline Tobacco smoke Acetaminophen May require decrease in dose upon smoking cessation Adrenergic agonists (e.g., prazosin) May require decrease in dose upon smoking cessation Adrenergic antagonists (e.g., phenylephrine) Interference of effects of one drug by the comedications or tobacco smoke is termed “Drug interaction”. Drugs for which induced metabolism because of cigarette smoking may have clinical consequence include theophylline, caffeine, tacrine, imipramine, haloperidol, pentazocine, propranolol, flecainide and estradiol. The amount of tobacco smoking needed to have an effect has not been established, and the assumption is that any smoker is susceptible to the same degree of interaction. The mechanism involved in most interactions between cigarette smoking and drugs involves the induction of metabolism. "̻�;�s�1���{�c�#�)���/�<0 q�[r�2�-9o�p����l�.
