Method of treatment of calcium disorders using phosphonoalkane-polycarboxylic acids

A method for the treatment of diseases relating to the abnormal deposition or dissolution of difficultly soluble calcium salts in the body of warm-blooded animals which consists of administering orally or parenterally to said warm-blooded animals, a safe but effective amount for said treatment of at least one pharmacologically acceptable phosphonoalkane-polycarboxylic acid derivative being a member selected from the group consisting of

• A. at least one phosphonoalkane-polycarboxylic acid of the formula ##EQU13## wherein R is selected from the group consisting of hydrogen and alkyl having 1 to 3 carbon atoms,
• wherein R.sub.1 is selected from the group consisting of ##EQU14## and whrein R.sub.2 is selected from the group consisting of hydrogen, alkyl having 1 to 3 carbon atoms, and -CH.sub.2 -CHRCOOH, and
• B. a non-toxic pharmacologically acceptable water-soluble salt of (A).
