Which schedule includes drugs for anti-diarrheal, antitussive, and analgesic purposes?

The correct choice addresses Schedule V, which encompasses drugs that are commonly used for their therapeutic effects while having a lower potential for abuse compared to drugs in other schedules. Schedule V drugs often include medications that are effective for treating conditions such as diarrhea, cough, and mild pain.

Examples of drugs in this schedule are those that contain low doses of opioids, like codeine, which may be used as an antitussive or for mild analgesic purposes. Additionally, certain formulations for treating diarrhea, such as those containing diphenoxylate, also fall within this category. The regulations surrounding these drugs reflect their accepted medical use and the relatively low risk of addiction when compared to those in higher schedules.

In contrast, other schedules may include substances that have stricter control due to higher abuse potential or no accepted medicinal uses at all.
