From: Smoking and antidepressants pharmacokinetics: a systematic review

Study	Drug	Country	N total/N smokers	Age	Men (%)	Main findings	Study limitations
Lundmarck et al. [12]	Fluoxetine	Sweden	291/138	43	39	No significant correlation between serum levels of FLX and smoking habits was found	Possibility of interactions with other medications
Koelch et al. [13]	Fluoxetine	Germany	65/13	14.6	37.0	Serum concentrations of the active moiety and NORFLX were significantly correlated with smoking status	Possibility of interactions with other medications
						Serum levels of the active moiety of FLX were 44% lower in smokers than in nonsmokers	Due to the ethnic polymorphism of CYP2D6 [6], the current results are not transferable to races other than Caucasians
						No significant correlation between serum levels of FLX and smoking habits was found	Population younger than 19
Lundmarck et al. [14]	Sertraline	Sweden	319/89	54.4	31	Smokers had significantly lower concentration-to-dose (C/D) mean ratios of serum sertraline and its main metabolite desmethylsertraline than nonsmokers	Possibility of interactions with other medications
Taurines et al. [15]	Sertraline	Germany	85/5	14.8	45.1	No significant correlation between serum levels of Sertraline and smoking habits was found	Possibility of interactions with other medications
							No standardization of timing of blood withdrawal and length of treatment as well as patient compliance
							Low number of subjects taking high doses of sertraline
							Population younger than 19
Reis et al. [16]	Escitalopram	Sweden	130/31	51	32	No significant correlation between serum levels of Escitalopram and smoking habits was found	76% of the patients took one or more drugs in addition to escitalopram
Reis et al. [17]	Citalopram	Sweden	19/10	<21	18.8	No significant correlation between serum levels of Citalopram and smoking habits was found	Possibility of interactions with other medications
Reis et al. [17]	Citalopram	Sweden	19/10	<21	18.8		Population younger than 21
Spigset et al. [18]	Fluvoxamine	Sweden	24/12	36.7	58.3	Cmax, and AUC were significantly lower in the smokers than in the nonsmokers	Only 50 mg/day of FLV was tested

Carrillo et al. [19]	Fluvoxamine	Sweden	14/6	33.9	50	Among extensive metabolizers (CYP1A2 e CYP 2D6) there was no difference in FLV kinetics between smokers and nonsmokers	Only 50 mg/day of FLV was tested
							Small sample size
							Limited to extensive metabolizers
