Abstract: The invention relates to a method of prevention or treatment of a condition such as magnesium deficiency or deficit or abnormality, creatine or creatine phosphate (phosphocreatine) deficiency or abnormality, parathyroid hormone (PTH) excess or abnormality, sodium deficiency or abnormality, potassium deficiency or abnormality, antidiuretic hormone excess or abnormality or a condition characterised by abnormal levels of parathyroid hormone related protein (PTHrP). In the method, a therapeutic quantity of a neutral to mildly alkaline solution of a magnesium salt comprising bicarbonate ions is administered to the patient.

Abstract: A method and an apparatus for preparing a substantially clear aqueous solution containing magnesium bicarbonate are disclosed. One method of preparing a substantially clear aqueous solution containing magnesium bicarbonate, includes contacting, with species resulting from the dissolution of carbon dioxide in water, an aqueous suspension of magnesium carbonate, at suitable conditions of pressure and temperature, so as to obtain an aqueous solution of magnesium bicarbonate and controlling the pH of the said solution so that, after reaction of the said species with the magnesium carbonate, the final pH falls within a range of from about 8.0 to about 8.8.

Abstract: An aqueous neutral to mildly alkaline metal bicarbonate solution is disclosed. The solution comprises metal bicarbonate dissolved in the solution, the metal bicarbonate comprising bicarbonate anions and metal cations. In addition there is a pH adjusting agent in the solution in an amount whereby the solution is at a neutral to mildly alkaline pH. Also disclosed is a process of preparing an aqueous neutral to mildly alkaline metal bicarbonate solution comprising bicarbonate anions and metal cations. The process comprises reacting a compound selected from the group consisting of metal carbonate, metal carbonate hydroxide, metal oxide, metal hydroxide and any mixture thereof with an effective concentration of a pH adjusting agent to produce the aqueous neutral to mildly alkaline metal bicarbonate solution, wherein the pH adjusting agent is present in an amount whereby the solution is at a neutral to mildly alkaline pH.
