Several lines of evidence have demonstrated that the local bone tissue renin-angiotensin system (RAS) is directly involved in bone metabolism and influences the bone health. This review aimed to assess the role of RAS in bone metabolism and comparative effectiveness of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) in reducing the bone fractures. In summary, the clinical trials, in vivo studies, and functional - pharmacological experiments suggested that the RAS regulates bone marrow metabolism and influences the bone health. Hence, it warrants further investigation on the role of ACEIs and ARBs in reducing risk fractures.
