Ibandronic acid is a highly active nitrogen-containing bisphosphonate that selectively acts on bone tissue and specifically inhibits osteoclast activity and has no direct effect on bone formation. The drug does not affect the process of osteoclast pool replenishment. In women during menopause, it reduces the increased rate of bone turnover to premenopausal levels, which leads to a progressive increase in bone mass and a decrease in the frequency of fractures.
