Ipriflavone (INN, JAN; brand name Yambolap) is a synthetic isoflavone which may be used to inhibit bone resorption,^[2] maintain bone density and to prevent osteoporosis in postmenopausal women.^[1] It is not used to treat osteoporosis. It slows down the action of the osteoclasts (bone-eroding cells), possibly allowing the osteoblasts (bone-building cells) to build up bone mass.

A clinical trial reported in 2001 that it was not effective in prevention or treatment of osteoporosis.^[3]

A double-blind study reveals that ipriflavone might be effective on reducing tinnitus on otosclerosis sufferers.^[4]

Ipriflavone has been described as a phytoestrogen.^[5] However, this is incorrect, as the drug does not bind to or activate the estrogen receptor and shows no estrogenic effects in postmenopausal women.^[6]^[7] The drug prevents bone loss via mechanisms that are distinct from those of estrogens.^[5]
