Clinical Trials

Several clinical trials spanning Phase 2 through Phase 4 evaluate the efficacy of Milnacipran in chronic pain conditions, primarily focusing on osteoarthritis and fibromyalgia, including primary fibromyalgia. Sponsored by diverse industry, academic, and governmental organizations—such as Forest Laboratories, Cypress Bioscience, Eli Lilly and Company, Banner Health, University of California San Diego, and the US Department of Veterans Affairs—the study portfolio includes both completed and terminated trials.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Milnacipran selectively inhibits the norepinephrine transporter (NET) and serotonin transporter (SERT) with IC50 values of 77 nM and 420 nM, respectively, thereby preventing monoamine reuptake and elevating extracellular concentrations of norepinephrine and serotonin. This sustained neurotransmitter elevation enhances descending inhibitory pain pathways within the central nervous system, providing the mechanism by which it alleviates chronic pain in clinical conditions such as fibromyalgia and osteoarthritis.

Appendix RUO and cGMP Quality Standards
