Which of the following drugs is classified as a Schedule II drug?

Cocaine is classified as a Schedule II drug due to its high potential for abuse, which can lead to severe psychological or physical dependence. Schedule II drugs are substances that are accepted for medical use in the United States but also carry a significant risk for addiction and misuse. Cocaine has recognized medical applications, such as in certain surgical procedures as a local anesthetic, but due to its potential for abuse, it is tightly regulated.

In contrast, acetaminophen, loratadine, and ibuprofen do not fall under the Schedule II category. Acetaminophen is a widely used over-the-counter pain reliever and fever reducer. Loratadine is an antihistamine used to treat allergies, and ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) used for pain and inflammation. Neither of these drugs presents the same level of abuse risk as cocaine, which is why they are classified differently.
