VISIPAQUE 320 (iodixanol)

X-Ray Contrast Activity Trial Activity: Mature
Cardiovascular Approved 1996-03-22

Visipaque 320 is an iso-osmolar, nonionic radiographic contrast agent used to visualize internal structures and blood vessels during diagnostic imaging. It is indicated for intra-arterial procedures (such as angiocardiography, peripheral arteriography, and cerebral arteriography) in adults and pediatric patients of all ages. For intravenous procedures, including CT imaging of the head and body, excretory urography, and coronary CT angiography (CCTA), it is indicated for adults and pediatric patients 12 years of age and older. By enhancing image clarity, it assists in the diagnostic evaluation of vascular and organ-related health concerns.

How VISIPAQUE 320 Works

Iodixanol provides radiographic opacification of blood vessels in the path of flow, allowing for the visualization of internal structures until significant hemodilution occurs. In general body imaging, the agent diffuses from the vascular space into the extravascular space. While it does not cross an intact blood-brain barrier, the agent will accumulate in the interstitial space of the brain in regions where the barrier has been disrupted by pathology.

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
