Summary

This trial aims to study whether or not anti-convulsants or anti-depressants are more effective for treating chronic pain, as well as to build a model to help predict which medication may work better for individual patients based on clinical characteristics.

Who is the study for?
This trial is for adults over 18 with chronic pain lasting more than 3 months, who could be treated with anti-convulsants or anti-depressants. Patients must have a balanced chance of benefiting from either medication as judged by their doctor. Those with conditions that prevent the use of these drugs or who refuse to participate are excluded.
What is being tested?
The study compares the effectiveness of two common chronic pain treatments: anti-convulsant and anti-depressant medications. It involves randomly assigning patients to one treatment group during clinic visits using an open-source system called CHOIR, which tracks patient outcomes.
What are the potential side effects?
Potential side effects from the medications may include dizziness, drowsiness, nausea, weight changes, mood swings, and possible drug interactions. The specific side effects can vary based on individual health conditions and the type of medication prescribed.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Anti-depressant medicationExperimental Treatment1 Intervention
The participants will be randomized to receiving an anti-depressant medication. Then using a patient centered approach, the participant and their treating pain provider will choose one medication within the class. Participants will continue the medications for at least 6 months provided that they can tolerate the side effects, consider the treatment effective, and are willing to continue the treatment. We are studying two classes of medications and specific names of medications do not apply.
Group II: Anti-convulsant medicationExperimental Treatment1 Intervention
The participants will be randomized to receiving an anti-convulsant medication. Then using a patient centered approach, the participant and their treating pain provider will choose one medication within the class. Participants will continue the medications for at least 6 months provided that they can tolerate the side effects, consider the treatment effective, and are willing to continue the treatment. We are studying two classes of medications and specific names of medications do not apply.
