Question

DOC for smoking cessation?

• A. Acamprosate
• B. Varenicline
• C. Thalidomide
• D. Tryptophan

Answer 1

The Correct Option is B

In the field of pharmacology, particularly concerning treatments for smoking cessation, several medications are available, each targeting different mechanisms to help individuals quit smoking. Among the options provided, we must determine the drug of choice (DOC) specifically for aiding smoking cessation.

Let's evaluate the options one by one:

• Acamprosate: Primarily used for maintaining sobriety in alcohol-dependent patients. It is not typically used for smoking cessation.
• Varenicline: This medication is specifically designed to assist with smoking cessation. It works by partially stimulating nicotine receptors in the brain and blocking nicotine, which reduces cravings and withdrawal symptoms.
• Thalidomide: An immunomodulatory drug, used for conditions like leprosy and multiple myeloma, not smoking cessation.
• Tryptophan: An amino acid involved in serotonin production; it does not have a role in quitting smoking.

Given the explanations above, the correct answer for the drug of choice used in smoking cessation is: Varenicline.
