The invention further provides pharmaceutical compositions comprising the compounds of formula (I), and methods for treating or preventing diseases, disorders, conditions, or symptoms mediated by an ER which comprise administering to a mammalian subject in need of treatment therewith, an effective amount of a compound of formula (I), or a pharmaceutically acceptable salt, stereoisomer, or prodrug thereof, or a pharmaceutically acceptable salt of the prodrug, or a pharmaceutical composition comprising a compound of formula (I), or a pharmaceutically acceptable salt, stereoisomer, or prodrug thereof, or a pharmaceutically acceptable salt of the prodrug. The invention further provides pharmaceutical compositions comprising combinations of the compounds of formula (I) and one or more of sodium fluoride, estrogen, a bone anabolic agent, a growth hormone or growth hormone secretagogue, a prostaglandin agonist/antagonist, and a parathyroid hormone, and methods of treating or preventing diseases, disorders, conditions, or symptoms mediated by an ER comprising the administration of an effective amount of such combination to a mammalian subject in need of treatment therewith.
