Abstract

Fibromyalgia (FM) is a chronic complex musculoskeletal disorder characterized by widespread musculoskeletal pain accompanied by fatigue, sleep disturbance, memory defects and mood changes. Fisetin, a plant flavonoid polyphenol, has been reported to possess potent antioxidant, antinociceptive and neuroprotective activities. The present study aimed to evaluate the efficacy of fisetin against reserpine‑induced FM (RIF) in rats. RIF was induced in male Wistar rats (180‑220 gm) using reserpine (1 mg/kg; subcutaneous; once daily for 3 consecutive days) and the rats were treated with fisetin (5, 10 and 25 mg/kg) for 21 days. Various behavioral, biochemical and molecular parameters were evaluated. Administration of reserpine induced allodynia, hyperalgesia and depression, which were significantly ameliorated (P<0.05) by fisetin (10 and 25 mg/kg), as reflected by an increase in paw and tail withdrawal latency, increased paw withdrawal threshold, and decreased immobility time. Reserpine led to decreased biogenic amine levels [5‑hydroxytryptamine (5‑HT), noradrenaline (NA) and dopamine (DA)] and increased the ratio to their metabolite 3,4‑dihydroxyphenylacetic acid. 5‑hydroxyindoleacetic acid in the spinal cord, thalamus and prefrontal cortex was significantly decreased (P<0.05) by fisetin. Immunohistological analysis of brain tissue revealed that fisetin significantly inhibited (P<0.05) reserpine‑induced depletion of 5‑HT. It also significantly inhibited (P<0.05) elevated oxido‑nitrosative stress and reactive oxygen species (ROS) levels, as analyzed by flow cytometry in RIF rats. Fisetin exerts its antinociceptive and anti‑depressive potential via modulation of decreased levels of biogenic amines (5‑HT, NA and DA), elevated oxido‑nitrosative stress and ROS to ameliorate allodynia, hyperalgesia, and depression in experimental RIF.
