Shortage of medicine containing SODIUM CELLULOSE PHOSPHATE

Dear Madame, Sir,

I am desperately searching for a medicine that contains SODIUM CELLULOSE PHOSPHATE. Recently CALCISORB (3M Pharmaceuticals), CALCIBIND and ANACALCIT (Belmac Laboratories Spain) have been used, but production has been interrupted. The medicine has been used to treat kidney stones caused by hypercalcuria.Can you please advise if such medicine is available in the market even with another commercial name, or if you are aware of any replacement?

Thank you in advance
