Effects of ipriflavone on bone mass and calcium metabolism in postmenopausal osteoporosis.
Recently it has been demonstrated that ipriflavone (IP), an isoflavone derivative, is able to increase bone mass in patients with established postmenopausal osteoporosis (PMO). Here we present a preliminary report of a 2-year multicenter, double-blind, placebo-controlled clinical study performed in order to evaluate the efficacy and tolerability of IP in PMO. A large number of patients with PMO, referred to 12 Italian centers, was randomly divided into 2 groups and treated with oral IP (600 mg/day) or placebo (Pl). All patients received an oral Ca supplement (1 g/day). One hundred and twenty six patients completed 1 year of the study. Bone mineral density (BMD) of the distal radius, measure…
Ipriflavone prevents radial bone loss in postmenopausal women with low bone mass over 2 years.
Two hundred and fifty-five postmenopausal women with distal forearm bone mineral density (BMD) 1 SD below the mean value for normal age-matched postmenopausal subjects were randomly allocated to a 2-year treatment with oral ipriflavone (200 mg t.i.d.) or a matched placebo, according to a double-masked, parallel-group design. All patients also received a 1 g/day calcium supplement. Distal radius BMD and bone metabolism markers were measured at baseline, and every 6 months. Blood haematology and chemistry and physical parameters were monitored at the same time. One hundred and ninety-six patients completed 2 years of treatment. BMD changes from baseline were analysed according to valid comple…
