Sodium lactate additive solution is available as a 5-mEq/mL concentrate for injection in 10-mL single-dose vials.3857 Each 10-mL vial contains 5.6 g of sodium lactate anhydrous (50 mEq each of sodium and lactate ion) in water for injection with hydrochloric acid for pH adjustment.3857
pH
The pH of a M solution in water for injection ranges from 6 to 7.3.3857
Osmolarity
The calculated osmolarity of the concentrate is approximately 10,000 mOsm/L.3857
Osmolality
The osmolality was determined to be 11,490 mOsm/kg by freezing-point depression and 10,665 mOsm/kg by vapor pressure.1071
Sodium lactate additive solution is administered by intravenous infusion only after dilution in a larger volume of fluid.3857 The appropriate volume of the concentrate may be added to infusion solutions to provide the desired number of milliequivalents of lactate ion with an equal number of milliequivalents of sodium ion.3857 A M (1.9%) solution may be prepared by diluting 50 mEq of the additive solution in 290 mL of a nonelectrolyte solution or sterile water for injection; the resulting solution is approximately isotonic and contains 167 mEq/L each of lactate and sodium ion in 300 mL.3857
Intact containers of sodium lactate additive solution should be stored at controlled room temperature.3857
