Loxoprofen patch for relieving shingles pain

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with herpes zoster and moderate-to-severe pain will receive either conventional therapy alone or conventional therapy plus a loxoprofen sodium patch applied to the affected skin. Pain severity using a numeric rating scale and safety labs will be tracked over the treatment period to compare analgesic effect and adverse events. The trial enrolls patients with rash onset within 90 days and excludes those with disseminated or ocular herpes zoster or prior patch use. The approach aims to provide localized NSAID analgesia with lower systemic exposure than oral medications.
