Which type of medication is used specifically for its ability to relieve symptoms?

The correct response is therapeutic agents, as these medications are designed specifically to relieve symptoms associated with various medical conditions. The primary focus of therapeutic agents is to alleviate discomfort and improve the overall quality of life of patients by addressing their symptoms directly. These agents can include a wide variety of medications, such as those for pain relief, managing anxiety, or controlling high blood pressure, among others.

While other options like analgesics and antipyretics can also relieve symptoms—analgesics specifically target pain and antipyretics are used to reduce fever—they fall under narrower categories. Preventive medications, on the other hand, are intended to prevent the onset of a condition or complication rather than relieve existing symptoms. Thus, they do not fit the description of being used specifically for symptom relief in the same broad context as therapeutic agents do.
