- Participants first receive a Ranolazine 500 mg tablet twice daily for 12 weeks, they then receive a Placebo tablet (matching Ranolazine 500 mg tablets) twice daily for 12 weeks. This treatment will be given to participants with either active CD or patients with CD that is in remission but who experience continued symptoms
