Abstract
Abstract Glucose polymers having an average chain length of 3 - 8 units are added to an electrolyte solution which normally has a saline taste in an amount to substantially disguise the saline taste of the electrolyte solution. Preferably, the polymer is added in an amount in the range of 15% to 50% by weight and the electrolyte solution contains the usual chloride salts of calcium, magnesium and potassium with the solution having a pH in the range of 3 - 6.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
49 words
A process for disguising saline taste in a pharmaceutical electrolyte solution comprising intermixing with a pharmaceutical electrolyte solution a glucose polymer having an average short-chain length of 3-8 units, in an effective amount to substantially disguise the saline taste of said pharmaceutical electrolyte solution without substantial adverse gastrointestinal effects.
Claim 2
Dependent Claim
49 words
A process for disguising saline taste in a pharmaceutical electrolyte solution comprising intermixing with a pharmaceutical electrolyte solution a glucose polymer having an average short-chain length of 3-8 units, in an effective amount to substantially disguise the saline taste of said pharmaceutical electrolyte solution without substantial adverse gastrointestinal effects.
Claim 3
Dependent Claim
19 words
The process as defined in claim 1 wherein said average chain length of said glucose polymer is 5 units.
Claim 4
Dependent Claim
30 words
The process as defined in claim 1 wherein said glucose polymer is added in an amount of at least 15% by weight based on the total weight of said solution.
Claim 5
Dependent Claim
25 words
The process as defined in claim 1 wherein said pharmaceutical electrolyte solution is composed of at least the chloride salts of calcium, magnesium and potassium.
Claim 6
Dependent Claim
27 words
The process as defined in claim 1 wherein said glucose polymer is dissolved in an aqueous solution and heated prior to intermixing with said pharmaceutical electrolyte solution.
Claim 7
Dependent Claim
22 words
The process as defined in claim 1 wherein the pH of said solution is adjusted to a range of 3 - 6.
Claim 8
Dependent Claim
49 words
A pharmaceutical electrolyte solution having a disguised saline taste comprising a pharmaceutical electrolyte solution and a glucose polymer having an average shortchain length of 3-8 units, said glucose polymer present in an effective amount to substantially disguise the saline taste of said electrolyte solution without substantial adverse gastrointestinal effects.
Claim 9
Dependent Claim
49 words
A pharmaceutical electrolyte solution having a disguised saline taste comprising a pharmaceutical electrolyte solution and a glucose polymer having an average shortchain length of 3-8 units, said glucose polymer present in an effective amount to substantially disguise the saline taste of said electrolyte solution without substantial adverse gastrointestinal effects.
Claim 10
Dependent Claim
19 words
The composition as defined in claim 7 wherein the average chain length of said glucose polymer is 5 units.
Claim 11
Dependent Claim
30 words
The composition as defined in claim 7 wherein said glucose polymer is present in an amount of at least 15% by weight based on the total weight of said solution.
Claim 12
Dependent Claim
25 words
The composition as defined in claim 7 wherein said pharmaceutical electrolyte solution is composed of at least the chloride salts of calcium, magnesium and potassium.
Claim 13
Dependent Claim
20 words
The composition as defined in claim 7 wherein said solution has a pH in the range of 3 - 6.
