Benzodiazepines are often the drug of choice for managing anxiety and insomnia. Which statement best explains why?
1. Benzodiazepines are the most effective.
2. Benzodiazepines have the lowest risk of dependency and tolerance.
3. Benzodiazepines are most likely to be covered under insurance premiums.
4. Benzodiazepines are the most affordable.
Correct Answer: 2
Rationale: Benzodiazepines have a lower risk of dependency and tolerance than do other drugs used for anxiety and insomnia (such as the barbiturates). They are not necessarily more effective, affordable, or likely to be covered under insurance premiums. Although economics is an important factor in pharmacology, drug safety is essential for widespread use.
