How DIVALPROEX SODIUM Works

Divalproex sodium functions by dissociating into the valproate ion within the gastrointestinal tract. While the exact therapeutic mechanisms have not been definitively established, the drug's activity in treating epilepsy is believed to be related to its effect on brain chemistry. Specifically, it is suggested that valproate works by increasing the concentrations of gamma-aminobutyric acid (GABA), which is an inhibitory neurotransmitter in the brain.

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
