Market Dynamics and Patent Landscape for ATC Class B05 - Blood Substitutes and Perfusion Solutions

Last updated: December 30, 2025

Summary

The ATC classification B05 encompasses blood substitutes and perfusion solutions, critical components in transfusion medicine and clinical perfusion. This report explores the evolving market landscape, driven by clinical needs, regulatory shifts, technological advancements, and patent strategies that shape innovation pathways. It provides an in-depth analysis of current market drivers, competitive dynamics, emerging innovation trends, and the patent environment, equipping stakeholders with a comprehensive understanding to navigate this specialized sector.


What are Blood Substitutes and Perfusion Solutions?

Blood Substitutes are biologically compatible fluids designed to mimic the oxygen-carrying function of erythrocytes in transfusions, thereby reducing reliance on donated blood. Types include:

  • Hemoglobin-based oxygen carriers (HBOCs): Cell-free hemoglobin molecules
  • Perfluorocarbon emulsions (PFCs): Synthetic oxygen carriers

Perfusion Solutions, also within B05, include fluids used during extracorporeal circulation, such as:

  • Crystalloids and colloids
  • Specific solutions like plasma expanders

What Are the Key Market Drivers?

1. Increasing Clinical Demand for Blood Substitutes

  • Blood shortages: Global blood supply variability, especially in low- and middle-income countries.
  • Aging populations: Rising need for transfusions in surgeries and trauma care.
  • Military and emergency scenarios: Need for portable, storable oxygen carriers.

2. Technological Advances

  • Development of next-generation HBOCs with better oxygen delivery, stability, and reduced side effects.
  • Improvements in PFC formulations for higher oxygen affinity and biocompatibility.

3. Regulatory and Ethical Pressures

  • Ethical concerns over blood donation and screening.
  • Stricter safety standards favoring synthetic alternatives.

4. Strategic Collaborations and Investment

  • Major pharma investments and collaborations, e.g., Hemoglobin oxygen carriers by Hemoglobin Technology.
  • Increasing patent filings, indicative of innovation intensity.
