Area of Science:

Pharmaceutical Sciences
Biochemistry

Context:

Hemodialysis fluid preparation
Bicarbonate solubility challenges
Mineral precipitation in solutions

Purpose:

To overcome fabrication issues in concentrated bicarbonate hemodialysis solutions
To develop a stable and effective hemodialysis fluid formulation
To prevent calcium, magnesium, and ferric carbonate precipitation

Summary:

A two-solution approach was developed to address sodium bicarbonate's low solubility and prevent carbonate precipitation.
The first solution contains essential elements (excluding bicarbonate), while the second contains bicarbonate and potassium gluconate.
Potassium gluconate complexes iron, preventing ferric carbonate precipitates, ensuring a stable final hemodialysis solution.

Impact:

Enables the production of stable concentrated bicarbonate hemodialysis solutions
Improves the quality and reliability of hemodialysis fluid manufacturing
Provides a pharmaceutical solution to common challenges in dialysis fluid formulation
