ENOXAPARIN SODIUM (PRESERVATIVE FREE) (enoxaparin sodium)

Trial Activity: Declining 14 active trials
Cardiovascular Approved 2010-07-23

Enoxaparin sodium is a low molecular weight heparin (LMWH) indicated for the prophylaxis of deep vein thrombosis (DVT) in patients undergoing abdominal, hip replacement, or knee replacement surgery, as well as medical patients with severely restricted mobility during acute illness. It is also indicated for the inpatient and outpatient treatment of acute DVT (with or without pulmonary embolism) and the management of acute coronary syndromes, including prophylaxis of ischemic complications in unstable angina and non-Q-wave myocardial infarction (NQMI), and the treatment of acute ST-segment elevation myocardial infarction (STEMI).

How ENOXAPARIN SODIUM (PRESERVATIVE FREE) Works

Enoxaparin is a low molecular weight heparin with antithrombotic properties. It acts by increasing the inhibition rate of clotting factors Xa and IIa (thrombin) by activating antithrombin III. Characteristically, enoxaparin exhibits a higher ratio of anti-Factor Xa to anti-Factor IIa activity (approximately 3:1 to 5:1) compared to unfractionated heparin.

ENOXAPARIN SODIUM (PRESERVATIVE FREE) Boxed Warning

SPINAL/EPIDURAL HEMATOMAS Epidural or spinal hematomas may occur in patients who are anticoagulated with low molecular weight heparins (LMWH) or heparinoids and are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures. Factors that can increase the risk of developing epidural or spinal hematomas in these patients include: Use of indwelling epidural catheter...

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
