Finding the right therapeutic approach for a patient does not have to be a challenging task for clinicians specializing in the treatment and management of pain. More often than not, pain management specialists are required to use more than one approach for patients with painful conditions. At the end of the day, it is up to the expert to make the final decision on the most effective treatments for his or her own patient.

Classifying the type of pain a patient is experiencing—sympathetic, neuropathic, visceral, somatic, or nociceptive—is where treatment begins.

If an agent within a drug class does not work, an alternative within the same class may still yield results, Dr. Uritsky told conference attendees. She also reminded the audience that  patients typically will not immediately feel any pain relief. 

“Many of these drugs take time to work. Often painful conditions do not occur overnight; therefore, careful drug selection, dose titration, and a variety of modalities may need to be employed to successfully achieve an acceptable level of pain control,” she said. “Additionally, patients may expect to experience no pain at all, which is often not achievable with available medication therapies.”

Selecting the right medication also depends on how it can complement nonpharmacologic modalities. Even within the same class, there are a variety of agents available for a pain management specialist to choose among.

“Agent selection should be based on patients and drug-related variables that may provide compelling indications,” Dr. Uritsky said. “Also, remember that there are evidence-based guidelines to help guide practitioners in making good therapeutic decisions.”
