The Efficacy and Safety of Pregabalin and Crisugabalin in Patients With Fibromyalgia
Sponsor: Beijing Tiantan Hospital
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.

Pregabalin
For the pregabalin group, treatment will be initiated at a dosage of 150 mg daily, administered into 2 or 3 divided doses. After 3 to 7 days, the dose will be titrated to 300 mg per day, with subsequent incremental increases of 150 mg daily permitted at 3-day to 7-day intervals based on therapeutic response and tolerability, up to a maximum dose of 450 mg daily.
Crisugabalin
For the crisugabalin group, therapy will begin at 20 mg twice daily, with a maximum allowable dose of 40 mg twice daily.
