Biphosphonates: and alternative to estrogen therapy in postmenopausal osteoporosis. Experience with alendronate

The post-menopausal osteoporosis represents an important complication during the climateric period; its clinical, economic and social weight is destined to increase with the aging of the population. The lack of oestrogens is the main etiopathogenetic element; this is the reason why the substitutive therapy during the menopause represents the most appropriate approach. However, the possibility of clinical contra-indications to the oestrogenic treatment, the compliance of the patient not always adequate, the possibility of side-effects, and the doubt about the real opportunity of this treatment in the advanced years, require therapeutic alternatives. Between these, the "inhibitors of the bone reuptake" are actually the more realistic and justified approach knowing the pathogenetic aspect of the disease.
