Effects of raloxifene on changes in bone density

Raloxifene hydrochloride therapy effectiveness in bone mineral density (BMD) changes compared to calcium and vitamin D3 therapy over a 2-year period. Case-control study: a group of 254 women was prescribed raloxifene (raloxifene hydrochloride) together with calcium and vitamin D3 while other group of 254 women used calcium and vitamin D3 therapy. BMD was measured at the hip, spine and forearm at the beginning and at the end of the 2-year period. Treatment with raloxifene resulted in a 3.7% increase in BMD at the spine in 98% of examinees. A 1.2% BMD increase was shown in 75% of examinees at the hip. A 1.2% decrease in BMD at forearm shown in 93% of examinees using raloxifene. The calcium and vitamin D3 therapy led to an increase in BMD in 58% examinees at the spine, in 56% at the hip and in 38% at the forearm, which was significantly lower than in women using raloxifene. Among women using calcium and vitamin D alone an average BMD decrease of 1.2% was registered on 42% of examinees at the spine, 2.6% decrease on 46% of examinees at the hip and 4.2% decrease on 35% of examinees at the forearm. Treatment with raloxifene resulted in a significant increase in BMD at the spine with odds ratio (OR 5.85, p <0.05) compared with calcium and vitamin D3 alone. There was no statistically proven increase in BMD at either the hip (OR 0.015) or forearm (OR 0.122).
