<p>512,203. Stabilising calcium sodium lactate solutions; medicines. WULFING, G. A. R. VON, and ROSSKOTHEN, E. M. H., (trading as WULFING, J. A.). Sept. 30,1938, No. 28501. Convention date, April 27. [Class 81 (i)] [Also in Group IV] A stable calcium sodium lactate solution, suitable for parenteral injection purposes is obtained by using an alkaline earth-gluconate as a stabiliser. An alkali gluconate is preferably also added and higher concentrations of calcium sodium lactate may be obtained by giving the solution a pH value of 6.2-6.6 as by adding gluconic or lactic acids. The stabilisers may be added in the form of gluconates, or gluconic acid may be added to the solution and neutralised with alkaline earth oxide with or without alkali carbonate. In examples concentrations of 6.5, 7.5 and 8.4 per cent. of calcium sodium lactate are obtained with calcium or strontium gluconate, calcium and sodium gluconates, and calcium and sodium gluconates and lactic acid, respectively.</p> |
