简要总结
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.

结局指标
主要结局
the average numeric rating scale score over the past 24 hours, rated each morning upon awakening and average over 7 days at week 4
时间窗: At week 4 after experimental drug medication
The numeric rating scale (NRS) score is a way to quantify the degree of subjective feelings such as pain using numbers. Generally, 0 represents no pain, and 10 represents the most severe pain. A higher score indicates more severe pain.
次要结局
- The worst numeric rating scale score(at weeks 1, 2, 4, 8, and 12 after experimental drug medication)
- Proportion of Patients Achieving Pain Reduction(at weeks 1, 2, 4, 8, and 12 after experimental drug medication)
- Proportion of patients developing postherpetic neuralgia(at week 12 after experimental drug medication)
- The type of analgesics and average weekly consumption per analgesics(at weeks 4, 8, and 12 after experimental drug medication)
- The 12-item Short-Form Health Survey (SF-12) score(at weeks 4, 8, and 12 after experimental drug medication)
- The Medical Outcomes Study Sleep Scale (MOS)(at weeks 4, 8, and 12 after experimental drug medication)
- Adverse events(Through study completion, an average of 12 weeks)
