  • Patent number: 4820870
    Abstract: The invention provides a novel acidic alkali citrate having the formula K.sub.6 Na.sub.6 H.sub.3 (C.sub.6 0.sub.7 H.sub.5).sub.5 . 2-4 H.sub.2 O made by dissolving either(a) trisodium citrate.times.2 H.sub.2 O, tripotassium citrate.times.1 H.sub.2 O, and citric acid in a mole ratio of 2:2:1 in 3 to 5 times the quantity by weight of boiling demineralized water, based on the weight of the citric acid and maintaining the solution at a temperature not lower than 60.degree. C.; or(b) citric acid at 90.degree. C. while stirring in .01 to 1 times its weight of demineralized water and then adding sodium carbonate and potassium carbonate to give a mole ratio of 3:3:5 of sodium carbonate: potassium carbonate:citric acid,and quick drying the homogeneous solution obtained. Therapeutic agents for the treatment of urolithiasis and removal, or preventing recurrence, of urine stones comprising said acidic alkali citrate are provided.

  • Patent number: 4400535
    Abstract: The invention provides a novel acidic alkali citrate having the formula K.sub.6 Na.sub.6 H.sub.3 (C.sub.6 O.sub.7 H.sub.5).sub.5.2-4 H.sub.2 O made by dissolving either(a) trisodium citrate.times.2 H.sub.2 O, tripotassium citrate.times.1 H.sub.2 O, and citric acid in a mole ratio of 2:2:1 in 3 to 5 times the quantity by weight of boiling dimineralized water, based on the weight of the citric acid and maintaining the solution at a temperature not lower than 60.degree. C.; or(b) citric acid at 90.degree. C. while stirring in 0.1 to 1 times its weight of demineralized water and then adding sodium carbonate and potassium carbonate to give a mole ratio of 3:3:5 of sodium carbonate:potassium carbonate:citric acid,and quick drying the homogeneous solution obtained. Therapeutic agents for the treatment of urolithiasis and removal, or preventing recurrence, of urine stones comprising said acidic alkali citrate are provided.
