Abstract: The present invention relates to pharmaceutical compositions, kits and methods comprising combinations of (?)-cis-6-phenyl-5-[4-(2-pyrrolidin-1-yl-ethoxy)-phenyl]-5,6,7,8-tetrahydro-naphthalene-2-ol or nontoxic pharmacologically acceptable acid addition salts thereof and estrogens. The present invention also relates to pharmaceutical compositions, kits and methods comprising combinations of (?)-cis-6-phenyl-5-[4-(2-pyrrolidin-1-yl-ethoxy)-phenyl]-5,6,7,8-tetrahydro-naphthalene-2-ol or nontoxic pharmacologically acceptable acid addition salts thereof, estrogens and progestins.

Abstract: Disclosed are methods for screening compounds to identify therapeutic candidates for modulating bone mass and/or bone mineral density, as well as methods for treating skeletal disorders characterized by decreased bone mass and/or bone mineral density. The methods are based upon the identification and use of agonists of the P2X7 receptor.

Abstract: This invention is directed to methods of treating conditions which present with low bone mass, particularly osteoporosis, frailty, an osteoporotic fracture, a bone defect, childhood idiopathic bone loss, alveolar bone loss, mandibular bone loss, bone fracture, osteotomy, bone loss associated with periodontitis, or prosthetic ingrowth comprising administering prostaglandin agonists which are EP4 receptor selective prostaglandin agonists. This invention is especially directed to those methods wherein the EP4 receptor selective agonist is a compound of Formula I: wherein the variables are as defined in the specification.

Abstract: This invention relates to methods for treating bone loss in a mammal by administering to the mammal a therapeutically effective amount of leptin or a leptin mimetic. This invention also relates to methods for treating bone fracture, enhancing bone healing following facial reconstruction, maxillary reconstruction or madibular reconstruction, enhancing long bone extension, enhancing the healing rate of a bone graft, enhancing prosthetic growth and inducing vertebral synostosis by administering a therapeutically effective amount of leptin or a leptin mimetic. This invention further relates to methods and compositions comprising leptin or a leptin mimetic and estrogen, a selective estrogen receptor modulator or a bisphonate for treating the above-recited diseases and conditions.

Abstract: This invention is directed to methods and pharmaceutical compositions comprising prostaglandin agonists which are userful to prevent bone loss, restore or augment bone mass and to enhance bone healing including the treatment of conditions which present with low bone mass, such as osteoporosis, and/or bone defects in vertebrates, and particularly mammals, including humans. This invention specifically relates to methods and pharmaceutical compositions comprising combinations of EP2 receptor selective agonists and EP4 receptor selective agonists and to methods and pharmaceutical compositions comprising agents which are agonists for both the EP2 receptor and the EP4 receptor.
