How OXTELLAR XR Works

The pharmacological activity of this drug is primarily exerted through its 10-monohydroxy metabolite (MHD), which blocks voltage-sensitive sodium channels. This action stabilizes hyperexcited neural membranes and inhibits repetitive neuronal firing, which helps prevent the spread of synaptic impulses. Additionally, the drug may contribute to anticonvulsant effects by increasing potassium conductance and modulating high-voltage activated calcium channels.

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
