Cytisine as a smoking cessation aid: Preliminary observations with a modified therapeutic scheme in real life.

Introduction: Cigarette smoke accounts for over 90,000 deaths each year in Italy. Tobacco dependence treatment guidelines suggest adopting an integrated pharmacological-behavioral model of intervention. Cytisine is a partial agonist of nicotinic receptors.

Cytisine Therapy Improved Smoking Cessation in the Randomized Screening and Multiple Intervention on Lung Epidemics Lung Cancer Screening Trial.

Introduction: Cytisine, a partial agonist-binding nicotine acetylcholine receptor, is a promising cessation intervention. We conducted a single-center, randomized, controlled trial (RCT) in Italy to assess the efficacy and tolerability of cytisine as a smoking cessation therapy among lung cancer screening participants.

Methods: From July 2019 to March 2020, the Screening and Multiple Intervention on Lung Epidemics RCT enrolled 869 current heavy tobacco users in a low-dose computed tomography screening program, with a randomized comparison of pharmacologic intervention with cytisine plus counseling (N = 470) versus counseling alone (N = 399).
