According to federal law, zaleplon is listed in which of the following controlled substance schedules?

Schedule II substances are defined by a high potential for abuse, leading to severe psychological or physical dependence. Examples include opioids like oxycodone and stimulants like amphetamine. Zaleplon does not meet this criterion, as it has a lower risk of addiction compared to Schedule II drugs.

Schedule III substances are recognized for a moderate potential for abuse, leading to low or moderate physical dependence or high psychological dependence. Examples include anabolic steroids and certain barbiturates. Zaleplon is not classified here because its abuse potential is lower than that of Schedule III substances.

Schedule V substances have the lowest potential for abuse and are typically comprised of preparations that contain limited quantities of certain narcotics. Examples include cough preparations with less than 200 mg of codeine per 100 ml. Zaleplon does not qualify for this schedule, as its potential for abuse is higher than that of Schedule V substances.
