Which drug is known to be a controlled substance?

Lyrica, known generically as pregabalin, is recognized as a controlled substance due to its potential for abuse and dependence. It is classified as a Schedule V controlled substance in the United States, which indicates that while it has legitimate medical uses—such as for managing neuropathic pain, fibromyalgia, and seizures—it also carries a risk of misuse. The scheduling helps regulate its prescription and distribution to minimize the likelihood of addiction or abuse.

In contrast, the other medications listed—naproxen, alendronate sodium, and pravastatin calcium—are not classified as controlled substances. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID), alendronate sodium is used primarily for the treatment of osteoporosis, and pravastatin calcium is a statin used to lower cholesterol levels. None of these drugs have the same potential for abuse, which is why they are not placed under the same regulatory controls as Lyrica.
