Efficacy and Safety of Milnacipran in the Treatment of Fibromyalgia in an Elderly Population

Phase 3
Terminated
Conditions
Fibromyalgia
Interventions
Registration Number
NCT01418651
Lead Sponsor
Banner Health
Brief Summary

Participants will undertake a 12-week, open-label study of milnacipran in a well-characterized cohort of patients with fibromyalgia syndrome (FMS) who are 65 years and older to investigate the short-term efficacy and safety of this drug in the elderly population. The investigators hypothesize that milnacipran will be effective in treating fibromyalgia syndrome (FMS), and will be prove to be safe when patients are selected for the absence of pre-existing blood pressure abnormalities and other serious medical conditions.
