Zipsor is a non-steroidal anti-inflammatory drug used to provide relief for adults and children 12 years and older who are experiencing mild to moderate acute pain.

How ZIPSOR Works

This drug works by inhibiting the enzymes COX-1 and COX-2, which are involved in the production of prostaglandins. By blocking prostaglandin synthesis, the medication reduces the substances that sensitize nerves and cause inflammation in peripheral tissues. This process results in decreased pain and swelling for the patient.

How We Calculate These Metrics

Trial Activity Stage

Measures the current development activity pattern based on trial phases, status, and trends. Important: This measures R&D activity, not commercial lifecycle.

Trial statuses: "Active" means recruiting or ongoing. "Completed" means reached planned endpoint. "Terminated" means stopped early—often due to safety, efficacy, or business reasons.

  • Growth: High proportion of early-phase trials (Phase 1/2), active development
  • Expansion: Significant Phase 3 activity, approaching or pursuing approvals
  • Mature: Substantial Phase 4 post-marketing studies
  • Stable: Mixed phase distribution, steady development
  • Declining: Low active trial ratio, reduced R&D investment
