Patent ID: 7994155

Claim:
A method of treating a condition of osteoporosis or bone fracture, which comprises administering an effective amount therefor of cyclic tetrasaccharide represented by cyclo {→6)-α-D-glucopyranosyl-(1→3)-α-D-glucopyranosyl-(1→6)-α-D-glucopyranosyl-(1→3)-α-D-glucopyranosyl-(1→} and/or a saccharide derivative thereof together with a calcium compound, said saccharide derivative being a member selected from the group consisting of saccharides (I) where one or more of the same or different glycosyl residues are bound to said cyclic tetrasaccharide; saccharides (II) where one or more of the same or different glycosyl residues selected from the group consisting of α-D-glucopyranosyl residue, β-D-galactopyranosyl residue, and β-D-chitosaminyl residue have been transferred to one or more hydroxyl groups of the saccharides (I); and saccharides (III) where one or more of the same or different glycolyl residues selected from the group consisting of α-D-glucopyranosyl residue, β-D-galactopyranosyl residue, and β-D-chitosaminyl residue have been transferred to the α-D-glucopyranosyl residue, β-D-galactopyranosyl residue, and β-D-chitosaminyl residue of said saccharides (II), wherein and whereby the mineral absorption of said calcium compound is accelerated.
