  • Publication number: 20010056060
    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.
