Which of the following substances is classified as a Schedule IV drug?

Diazepam is classified as a Schedule IV drug because it has a lower potential for abuse compared to substances in higher schedules, while still possessing acceptable medical uses. Scheduled drugs are categorized based on their potential for abuse, medical utility, and safety profile, with Schedule I representing the highest potential for abuse and no accepted medical use, and Schedule V having the lowest potential.

Diazepam, a benzodiazepine, is commonly prescribed for conditions such as anxiety, insomnia, and muscle spasms, making it a valuable medication for clinicians when used appropriately. While it can lead to physical dependence and has a risk of abuse, this risk is significantly lower than that associated with Schedule I, II, or III substances, which include more potent opioids and stimulants. Understanding these classifications is crucial for managing medications safely and effectively in the clinical setting.
