Which of the following is used in the treatment of narcotic dependence?

Naltrexone is specifically used in the treatment of narcotic dependence because it acts as an opioid antagonist. This means that it binds to the same receptors in the brain that opioids do but without activating them. By blocking these receptors, naltrexone effectively reduces the euphoric effects of opioids and can help individuals who are attempting to abstain from narcotics. It also helps to diminish cravings, making it a valuable component of a comprehensive treatment plan for opioid dependence.

In contrast, stimulants, beta blockers, and glucocorticoids are not used for the treatment of narcotic dependence. Stimulants are typically used to treat conditions like ADHD and narcolepsy, while beta blockers are primarily prescribed for cardiovascular issues, anxiety, and certain types of tremors. Glucocorticoids are anti-inflammatory medications used for a variety of conditions but do not have a role in treating substance use disorders. This highlights naltrexone’s unique role in addressing narcotic dependence through its mechanism of action at the opioid receptors.
