The Analgesic Efficacy and Safety of Mirogabalin in Patients With Herpes Zoster

Herpes zoster (HZ) is characterized by a painful dermatomal rash and significantly affects quality of life, with acute pain increasing the risk of postherpetic neuralgia. Although early antiviral therapy limits viral replication, its analgesic effect is insufficient, and many patients experience inadequate relief despite stepwise use of non-opioids and opioids. Gabapentinoids such as gabapentin and pregabalin are recommended adjuncts, but their efficacy in acute HZ is inconsistent and often accompanied by adverse effects that limit tolerability. Mirogabalin, a newer gabapentinoid approved for peripheral neuropathic pain, has higher affinity and slower dissociation from the α2δ-1 subunit, suggesting stronger analgesia with fewer central side effects. However, its role in managing acute HZ pain remains unknown. We therefore hypothesize that adding mirogabalin to conventional therapy will provide superior pain relief compared with standard treatment alone, and propose a prospective, randomized, controlled, open-label, blinded-endpoint trial to evaluate this.

The Efficacy and Safety of Pregabalin and Mirogabalin in Patients With Fibromyalgia

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. Mirogabalin, 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 mirogabalin in treating FM, with the aim of providing a better treatment option for FM patients.

Comparison of the Efficacy and Safety of Mirogabalin and Duloxetine in Chemotherapy-induced Peripheral Neuropathy in a Randomized Controlled Trial: a Quality of Life Study in Cancer Survivors

To conduct a two-arm, parallel, prospective, randomized controlled, open-label trial to compare the efficacy of the novel drug mirogabalin with the conventional treatment duloxetine in reducing pain associated with chemotherapy-induced peripheral neuropathy (CIPN). There will be a difference in pain reduction after 4 weeks of treatment between the mirogabalin group and the duloxetine group in patients with chemotherapy-induced peripheral neuropathy (CIPN). Participants will: * Take drug duloxetine or a mirogabalin every day for 4 weeks. * Visit the clinic once every 2 weeks for checkups and tests
