Smoking Cessation Agents: Pharmacology Made Easy & Clinically Relevant
Smoking cessation requires a multifactorial approach to achieve the desired quit rates for the patients we serve. Learning the pharmacology in a way that explains not only the how, but more importantly, the why is essential to this success.

This This Is Why pharmacology review examines the evidence-based pharmacologic and behavioral strategies for smoking cessation. The episode explores how combining medication with behavioral interventions can substantially improve abstinence rates and long-term success.
The review begins with the clinical relevance of smoking cessation, outlines the 5 A’s (Ask, Advise, Assess, Assist, Arrange) and 5 R’s (Relevance, Risks, Rewards, Roadblocks, Repeat), and then analyzes first-line pharmacologic options—bupropion, nicotine replacement therapy (NRT), and varenicline—alongside alternative agents such as nortriptyline and clonidine. Each therapy is discussed in terms of mechanism, dosing, timing in relation to quit date, advantages, disadvantages, contraindications, and monitoring requirements.
