Comparison between cytisine and Nicotine Replacement Therapy in smoking cessation among inpatient psychiatric patients

Abstract

Introduction: Smoking is more common among people with mental disorders and is associated with adverse effects. Some compounds, including nicotine and cytisine, have been used in many individuals to increase success in smoking cessation. In this study, the effect of cytisine on the smoking status of patients hospitalized in the psychiatry department was investigated.

Method: Forty-seven patients, hospitalized in the psychiatry ward, motivated to quit smoking, participated in this open-label randomized trial. Thirty patients used nicotine gums 2 mg (Nicolife®) for eight weeks, and the remaining took cytisine pills (Tabex®) according to the manufacturer’s instructions for 25 days. All patients were followed up for six months. The primary outcome was smoking cessation, measured by the mood and physical symptoms scale (MPSS), the AUDIT alcohol consumption questions (AUDIT-C), confirmatory factor analyses, and reliability of the modified cigarette evaluation questionnaire at the end of the 1st week and at 1st, 2nd and 6th months after quit day.

Findings: Only two out of 30 patients (6.66%) in the group taking Nicotine Replacement Therapy (NRT) could quit smoking entirely (no cigarettes after six months). In contrast, three out of 17 patients (17.64%) managed to do so in the cytisine group. The number of cigarettes smoked by the patients in both groups decreased, but the reduction was significant in the cytisine group.

Conclusion: Cytisine is an effective and suitable agent for smoking cessation in patients with psychological problems, with fewer adverse effects and more success rate compared to NRT.
