Start Date

Study Type

INTERVENTIONAL

Conditions

Pain Fibromyalgia Pregabalin

Summary

Fibromyalgia (FM) is a chronic pain syndrome characterized by widespread pain, fatigue, and emotional disorders. Its onset is related to factors such as central sensitization and imbalance of neurotransmitters. The current mainstream treatments include pregabalin, but the efficacy of pregabalin is limited, with only 25%-40% pain relief rate, and adverse reactions are common. crisugabalin, a new highly selective α2δ ligand, has shown potential in animal models or preliminary clinical trials, but there is insufficient evidence for its application in FM. This study aims to explore the effectiveness and safety of pregabalin or crisugabalin in treating FM, with the aim of providing a better treatment option for FM patients.
