Diethylpropion is classified under which controlled substance schedule?

Diethylpropion is classified under Schedule IV of the controlled substances. This classification is based on its potential for abuse relative to other substances. Schedule IV substances are considered to have a lower potential for abuse compared to those in Schedule II and III but can still lead to limited physical or psychological dependence.

Diethylpropion is primarily used as an appetite suppressant in the treatment of obesity and has been evaluated for its potential for misuse. The scheduling under Schedule IV allows for some degree of control, ensuring that diethylpropion is dispensed and used in a manner that mitigates risks associated with its abuse while still allowing for therapeutic use.

In contrast, substances in higher schedules, such as Schedule II, have a higher potential for abuse and addiction, which is not characteristic of diethylpropion. The classification rationale reflects both the pharmacological properties of the drug and the regulatory intent to manage its use safely.
