Effect of nicotine on 35% CO 2 -induced anxiety: A study in healthy volunteers

Panic disorder and cigarette smoking co-occur at a rate that exceeds what would be expected by chance. Theoretically, cigarette smoking may (a) attenuate panicky symptoms via cognitive factors or pharmacological action, (b) contribute to the development of panic disorder, or (c) share an etiological...

Zusammenfassung:Panic disorder and cigarette smoking co-occur at a rate that exceeds what would be expected by chance. Theoretically, cigarette smoking may (a) attenuate panicky symptoms via cognitive factors or pharmacological action, (b) contribute to the development of panic disorder, or (c) share an etiological vulnerability with panic. The present study was aimed at testing whether nicotine has a direct influence on laboratory-elicited panic. In a placebo-controlled, double-blind, randomized, cross-over study, 33 healthy nonsmokers underwent a 35% CO2 challenge after transdermal administration of a nicotine patch on one test day and a placebo patch on another test day. Physiological measures (blood pressure, heart rate) and rating scale scores (Panic Symptom List [PSL], Visual Analog Scale of Anxiety, State-Trait Anxiety Inventory) were assessed. Compared with the placebo condition, nicotine increased diastolic blood pressure (p
