Ipriflavone
Ipriflavone, a synthetic isoflavone derived from natural isoflavones found in soy, red clover, and other food sources, may also be effective in preventing and treating osteoporosis. Although several studies have found that ipriflavone prevents bone loss and increases bone density in menopausal women, other large-scale studies have failed to support these findings. Results from one study suggest that ipriflavone may even cause lymphocytopenia, a condition characterized by abnormally low white blood cell count. Further studies are needed to determine whether ipriflavone is safe and effective for the treatment and/or prevention of osteoporosis.

Ipriflavone Supplementation for Osteoporosis Prevention and Treatment?
 
Question
A patient has inquired about taking a calcium supplement with ipriflavone. Are there any benefits of this combination supplement vs calcium alone vis a vis osteoporosis, and are there any side effects?
Response from Jean-Yves Reginster, MD, PhD

Ipriflavone is a synthetic isoflavone derivative, which has been suggested to be an inhibitor of bone resorption and a stimulator of osteoblast activity in vitro in cell cultures and in vivo in experimental models of osteoporosis. Preliminary studies, mainly performed in Italy and Japan, suggested that ipriflavone (typical dosage 600 mg/day) is able to prevent bone loss, and some data even suggested that ipriflavone may increase bone mass in postmenopausal women. However, reports of lymphocytopenia in women taking ipriflavone generated concerns regarding the safety of this particular compound. In order to investigate the effect of oral ipriflavone in prevention of postmenopausal bone loss and to assess the safety profile of long-term treatment with ipriflavone in postmenopausal osteoporotic women, a prospective, randomized, placebo-controlled 4-year study was conducted in 474 postmenopausal white women with bone mineral densities below the threshold for a diagnosis of osteoporosis, according to World Health Organization classification (ie, a bone mineral density less than 2.5 standard deviations below the young adult mean).[1] The study concluded that ipriflavone, at the daily dose of 600 mg per day, combined with calcium 500 mg per day, had no significant benefit in terms of biochemical markers of bone remodeling, bone mineral density, or fracture incidence. Furthermore, lymphocytopenia occurred in a significant number of women treated with ipriflavone. The study investigators concluded that ipriflavone could not be considered an effective or safe medication in the treatment of osteoporosis. Use of this medication should be discouraged until more data allow reconsideration of this position.

Ipriflavone Supplements

Ipriflavone, a synthetic isoflavone, has shown some promise in its ability to conserve bone in postmenopausal women. Ipriflavone has also been shown to have a protective effect on bone density in pre-menopausal women taking gonadotropin-releasing hormone (GnRH) agonist, a treatment for endometriosis that triggers bone loss.

However, a definitive three-year study of more than 400 postmenopausal women concluded that ipriflavone did not prevent bone loss. Additionally, the compound was linked to lymphocytopenia (a reduction in lymphocytes) in a significant number of study participants. Lymphocytes are a type of white blood cell that helps the body fight infection.
