  • Patent number: 8541471
    Abstract: Compounds and pharmaceutical compositions for use in the treatment and/or prophylaxis of cartilage and/or bone conditions and for methods of treating such condition. The compounds are salts of strontium that have a water-solubility of from about 1 g/l to about 100 g/l at room temperature, especially amino acid salts of strontium or dicarboxylic acid salts of strontium. Examples of novel water-soluble strontium salts are e.g. strontium glutamate and strontium alpha-ketoglutarate. The present invention also relates to an improved method for preparing the strontium salt of glutamic acid.

  • Patent number: 8183409
    Abstract: A new method for preparing salts of metal cations and organic acids, especially divalent salts of alkaline earth metal ions from group II of the periodic system and carboxylic acids. The method comprising the use of a high temperature (about 90° or more) and, optionally. high pressure, in order to obtain a higher yield, purity and faster reaction speed than obtained with known synthesis methods. In particular, the present invention relates to the production of strontium salts of carboxylic acids. Novel strontium salts are also provided by the present method.
