Which of the following is an example of a Schedule III medication?

The correct choice, testosterone, is classified as a Schedule III medication under the Controlled Substances Act. Schedule III drugs are substances that have a moderate potential for abuse and are recognized for having accepted medical uses in the United States. Testosterone, commonly prescribed for hormone replacement therapy and certain medical conditions, fits this category due to its therapeutic benefits, yet still requires careful oversight due to potential for dependence and misuse.

In contrast, hydrocodone is more strictly regulated and has been moved to Schedule II because of its higher abuse potential. LSD is categorized as a Schedule I substance due to its lack of accepted medical use and high potential for abuse. Diazepam is classified as a Schedule IV medication, indicating lower potential for abuse compared to Schedule III drugs. Each of these classifications helps healthcare professionals regulate prescriptions and manage patient care effectively.
