1. A container system for peritoneal dialysis (PD) solutions, comprising:
- a first compartment containing a PD osmotic agent,a second compartment containing a PD buffer agent,wherein the first and second compartments are coupled, any of directly or indirectly, to support fluid transfer therebetween, andwherein the PD buffer agent comprises lactate and has a concentration of about 3-fold to about 15-fold higher than Normal PD buffer agent,such that a PD solution that results from a mixing of the PD osmotic agent and the PD buffer agent would have reduced glucose degradation products relative to PD solutions produced from any of a conventional two-bag and a dual chamber PD solution container system.

Abstract
The invention provides container systems, kits and methods for peritoneal dialysis (PD) solutions. Such a system, for example, includes a first compartment that contains a PD osmotic agent and a second compartment that contains a PD buffer agent. The compartments maintain their respective contents separately from one another for purposes of transport, storage and/or sterilization. However, the compartments are fluidly couplable, so that their respective contents can be combined with one another, e.g., following sterilization of the agents and prior to their introduction into the patient'"'"'s abdomen.

17. A container system for peritoneal dialysis (PD) solutions, comprising:
-
a first compartment containing a PD osmotic agent, a second compartment containing a PD buffer agent comprising lactate, wherein the first and second compartments are coupled for fluid transfer therebetween, wherein a ratio of a volumetric capacity of the first compartment to a volumetric capacity of the second compartment is in the range of about 20;
1 to about 200;
1,such that a PD solution that results from mixing of the PD osmotic agent and the PD buffer agent would have reduced glucose degradation products relative to PD solutions produced from any of a conventional two-bag and a dual chamber PD solution container system. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method for producing a peritoneal dialysis (PD) solution with reduced glucose degradation products (GDPs), comprising:
-
sterilizing a PD osmotic agent, sterilizing a PD buffer agent, where the PD buffer agent comprises lactate and has a concentration of about 3-fold to about 15-fold higher than Normal PD buffer agent, combining the sterilized PD osmotic agent with the sterilized PD buffer agent, thereby producing a PD solution with reduced GDPs relative to PD solutions produced from any of a conventional two-bag and a dual chamber PD solution container system. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37)

38. A container system for peritoneal dialysis (PD) solutions, comprising:
-
a first compartment containing a PD osmotic agent, a second compartment containing a PD buffer agent that comprises lactate, wherein the first and second compartments are coupled for fluid transfer therebetween, a volumetric capacity of the first compartment is in a range of about 1 liter to about 5 liters, and a volumetric capacity of the second compartment is in a range of about 5 milliliters to about 50 milliliters, and such that a PD solution that results from a mixing of the PD osmotic agent and the PD buffer agent has reduced glucose degradation products relative to PD solutions produced from any of a conventional two-bag and a dual chamber PD solution. - View Dependent Claims (39)
