The financial and social cost of hypertension and osteoporosis, clinically silent diseases, are determined by the consequences, such as a vascular disease and fractures. The relationship between these illnesses has not been clearly established, although many alterations in extracellular metabolism of calcium, which could determine the level of bone mineral density (BMD) in these patients, have been associated to hypertension. Despite these alterations, the lack of studies relating these two important diseases is surprising, and hypertension is not identified as a risk factor for osteoporosis. Interestingly, there is a lack of information of the long-term effects of antihypertensive treatment on bone mineral density, although 50 % of the hypertensive population is made up of postmenopausal women. Most studies analyzed the effects of thiazides and, to a lesser degree, the effects of calcium antagonist. The purpose of this review is evaluate the effect of the antihypertensive therapeutic group (diuretics, β-blockers, calcium antagonists, angiotensin converting enzyme) on the bone mineral density (BMD) and osteoporotic fracture.
