Mental disorders including anxiety and depression are common comorbidities in fibromyalgia patients, and exert a profound impact on their quality of life. Mirogabalin, a novel ligand for the αδ-subunit of voltage-gated calcium channels, shows analgesic effects in fibromyalgia and neuropathic pain models. To provide additional information regarding its potential utility for treating chronic pain, we examined its anxiolytic-like effects in rats repeatedly injected with acidic saline intramuscularly (Sluka model), as an experimental fibromyalgia model.
