Abstract

The present invention discloses glucose polymer-based solutions and methods for their preparation, which solutions can be used in medical treatments such as dialysis treatments. The glucose polymer-based solution preferably comprises a first solution containing icodextrin having a pH in the range of about 1.5 to about 5.0 and a buffer solution in the pH range of from about 7.0 to about 12.0, constructed and arranged to allow the glucose polymer-based solution to Mixed before infusing into patient. The glucose polymer-based solutions of the present invention can be prepared at physiological pH with minimal glucose degradation products.

Description

Background of the invention [0001] The present invention relates generally to medical treatments. More specifically, the present invention relates to fluids or solutions for use in dialysis therapy. [0002] Due to disease or injury or other causes, the kidney system can fail. In renal failure of any cause, several physiological disturbances are present. In the setting of renal failure, the excretion of water, minerals (eg Na, K, Cl, Ca, P, Mg, SO4) and the daily metabolic load of fixed ions is no longer possible to balance. In renal failure, toxic end products of nitrogen metabolism (such as urea, creatinine, uric acid, etc.) may accumulate in the blood and tissues. [0003] Dialysis is a method designed to separate elements in a solution by diffusing a solution through a semipermeable membrane through a concentration gradient (solute diffusion transfer). Examples of dialysis methods include hemodialysis, peritoneal dialysis and hemofiltration. [0004] Hemodialysis trea...
