A 45-year-old chronic smoker is being counselled for smoking cessation therapy. Which of the following statements regarding nicotine replacement and pharmacotherapy is correct?

Appeared in: INI-CET EXAM -2026

Explanation

Nicotine is an alkaline substance that is absorbed through the mucous membranes of the mouth when using products like gum or lozenges.
The absorption is pH-dependent and is most efficient in an alkaline environment.
Consuming acidic beverages like coffee, juice, or soft drinks lowers the pH in the mouth.
This acidic environment causes the nicotine to become ionized, which significantly reduces its absorption through the buccal mucosa.
Therefore, patients should be advised to avoid eating or drinking (especially acidic items) for 15 minutes before and during the use of nicotine gum to ensure its effectiveness.

Why Other Options Were Wrong

Option B: Studies have shown that the nicotine patch and nicotine gum have comparable efficacy when used as monotherapy. Neither is considered definitively superior to the other.
Option C: Varenicline is generally associated with a higher incidence of certain adverse effects, particularly nausea, which can be significant for many patients. Bupropion's most common side effects are insomnia and dry mouth.
Option D: Varenicline's prominent black box warning was for serious neuropsychiatric events, and this warning was removed by the U.S. FDA in 2016 after further studies. While there is a warning for cardiovascular events in patients with existing cardiovascular disease, the most known warning was for neuropsychiatric effects.

Clinical Relevance

Nursing practice connection: Knowing Pharmacotherapy and patient education for smoking cessation helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
A nurse's primary role in smoking cessation is patient education. This includes teaching the correct method of using NRTs, such as the 'chew and park' technique for nicotine gum, to maximize efficacy and minimize side effects.
It is crucial to assess for contraindications. For example, Bupropion is contraindicated in patients with a history of seizures or eating disorders.
Monitoring for and managing side effects is key to adherence. For Varenicline, advising the patient to take it with food and a full glass of water can mitigate nausea.

How to Approach the Question

First, identify that the question is asking for a correct statement about smoking cessation pharmacology. This requires factual recall.
Read the question stem carefully to understand the context: a chronic smoker being counseled.
Evaluate each option individually based on your knowledge of NRTs, Bupropion, and Varenicline.
For Option A, recall the absorption mechanism of buccal NRTs. Remember that nicotine is alkaline and requires a non-acidic environment.
For Option B, compare the efficacy of different NRT formulations. Recall that monotherapy efficacy is generally similar.
For Option C, compare the side effect profiles of Bupropion and Varenicline.
