Summary

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. Topical NSAIDs offer a promising alternative by delivering localized analgesia with reduced systemic exposure. Therefore, investigators hypothesize that loxoprofen sodium patch may effectively reduce the severity of HZ pain without significantly increasing adverse events.

Conditions

  • Herpes Zoster
  • Pain

Interventions

DRUG

Conventional therapy group

In the conventional therapy group, treatments will include opioids, antiviral drugs and so on.

DRUG

Loxoprofen sodium patch combined with conventional therapy group

In the loxoprofen sodium patch combined with conventional therapy group, apply the loxoprofen patch to the painful point near the herpes lesion. Use one patch per day, twice a day. In addition, the group will contain conventional treatment for HZ, except loxoprofen sodium patch, including opioids, antiviral drugs and so on.
