Zoledronic Acid is used for treatment of hypercalcemia of malignancy, for the treatment of bone metastasis associated with malignancies such as prostate and breast cancer, for the prevention of and treatment of osteoporosis and for the treatment of Paget's disease. Administration of Zoledronic Acid is complicated by what is described as “post-dosing syndrome” (PDS) and osteonecrosis of the jaw (ONJ). Inflammation may be the cause of these side effects, which could be decreased by the co-administration of steroids. This application is a method of use patent for the co-administration of steroids (oral, IV, IM, rectal, or by inhalation) with Zoledronic Acid and a composition of matter patent for mixing Methyl Prednisolone with Zoledronic Acid for infusion.

[Problem] To provide a compound which may be used in treating diseases in which a calcium sensing receptor (CaSR) is concerned, particularly hyperparathyroidism.

[Means for Resolution] It was found that novel pyrrolidine derivatives which are characterized by the possession of aminomethyl group substituted with arylalkyl group or the like, or salts thereof, have excellent CaSR agonistic regulatory activity and also have excellent selectivity with CYP2D6 inhibitory activity having a possibility of causing drug interaction. Based on the above, these novel pyrrolidine derivatives are useful as therapeutic agents for treating diseases in which CaSR is concerned (hyperparathyroidism, renal osteodystrophy, hypercalcemia and the like).

The invention relates to a process for treating unwanted moderately saline waters for producing waters acceptable for treating soil, such as for irrigation. The treated water is also suitable for human and livestock consumption. The process includes passing moderately saline waters having 0.05% or more by weight and less than 1.00% by weight of the salts of Na, K, Ca, Mg, Fe, Cl, SO₄, or CO₃ or combinations thereof through an ion exchange resin. The ion exchange resin is pre-treated to be saturated with multivalent cations. Preferred multivalent cations include calcium (Ca²+) or magnesium (Mg²+) ions, or combinations thereof. After passing through the ion exchange resin, the effluent has decreased sodium cations and increased calcium and/or magnesium cations compared to the pre-treated moderately saline water. As the moderately saline waters passes through the ion exchange resin, the sodium content of the resin rises as the multivalent cation content lowers until the resin is unacceptable for further water treatment in accordance with the present invention. To regenerate the ion exchange resin, the resin is flushed with a brine solution having more than 1.00% by weight of the salts of Na, K, Ca, Mg, Fe, Cl, SO4, or CO3. Preferably, the brine is particularly high in calcium and/or magnesium content and low in sodium. The brine solution is flushed through the ion exchange resin until the ion exchange resin is sufficiently saturated with multivalent cations to again process moderately saline water having high sodium content.

The invention relates to novel methods of using 2α-methyl-19-nor-20(S)-1α,25-dihydroxyvitamin D₃ or 2-methylene-19-nor-20(S)-1,25-dihydroxyvitamin D₃ to prevent Type 1 diabetes in a subject at risk of developing Type 1 diabetes without causing hypercalcemia in the subject.

The present invention relates to a pharmaceutical composition for the treatment of metabolic bone disease and the method of preparation thereof, and more particularly, to an improved pharmaceutical composition for the therapeutic treatment of metabolic disease and the method of preparation thereof, wherein said composition is prepared as a composite pharmaceutical agent which comprises calcitriol; which reduces the rate of spine fractures and increases bone density; alendronate, a bone resorption inhibitor, as two main active ingredients in an optimal mixing ratio to exert the greatest synergistic therapeutic effect; and adequate amount of other additives such as a resorption fortifier of alendronate. Thereof, the pharmaceutical composition according to the present invention can inhibit hypercalcemia caused when administered by calcitriol alone, compensate the inhibitory activity of bone remodeling caused by alendronate due to the presence of calcitriol, and improve drug compliance associated with the usual difficulty in administration as well as a side effect in esophagus, thus effectively preventing the occurence of osteoporosis.

Inhibitors of bone calcium resorption are administered to allow high doses of vitamin D compounds or mimetics to be given with the intent of treating non-calcium related diseases such as cancer, psoriasis, and autoimmune disease without the dangers of calcification of kidney, heart, and aorta. Inhibitors of bone calcium resorption include the bis-phosphonates, OPG (osteoprotegerin) or the soluble RANKL (receptor activator of NF-κB ligand) receptor known as sRANK (soluble RANK which is the protein expressed by the NF-κB gene), and function to block the availability of calcium from bone thereby preventing hypercalcemia and the resulting calcification of soft tissues. Thus, high doses of 1α,25-dihydroxyvitamin D₃ (1,25-(OH)₂D₃), its analogs, prodrugs, or mimetics can be utilized with minimal risk to a patient. Specifically, alendronate is shown to block the bone calcium mobilization activity of both 1,25-(OH)₂D₃ and its very potent analog, 2-methylene -19-nor-(20S)-1α,25-dihydroxyvitamin D_3.

The invention provides specific binding members (e.g., antibodies or antigen-binding fragments thereof) which bind to RANKL originating from multiple species. An epitope recognized by the specific binding members can be selected from surface exposed loop domains that bind to and activate its cognate receptor, RANK (Receptor Activator of NFkB), on the surface of osteoclast precursors and other cell types. The invention provides peptides for generating such anti-RANKL antibodies, including murine sequences, other non-human sequences and cross-reactive peptides. The specific binding members are useful in the diagnosis and treatment of lytic bone diseases, including osteoporosis, rheumatoid arthritis, bone metastasis and hypercalcemia of malignancy, glucocorticoid-induced bone loss, a periodontal disease or condition, a cancer and Juvenile Paget's Disease. The binding members can also be used in therapy in combination with chemotherapeutics or anti-cancer agents and/or with other antibodies or antigen-binding fragments thereof.
