Objective-Osteoporosis is increasingly common worldwide and there is growing concern that the long-term use of antipsychotic medications increases the risk of this disorder. In this review we consider whether antipsychotics may contribute to the development of osteoporosis through reductions in bone mineral density (BMD), discuss the possible mechanisms involved and consider the clinical implications of such a relationship. Methods-We searched the literature for studies in this area published between 1966 and 2010 using the Medline and PubMed databases and the following search terms: (schizophrenia OR antipsychotic OR neuroleptic) AND (osteoporosis OR hyperprolactinaemia OR bone mineral density).Results-The available data indicates that statistically significant reductions in bone mineral density are frequently seen in patients prescribed antipsychotic medications and suggests that there is a higher incidence of clinically significant reductions compared with the normal population.Conclusions-Clinicians should be aware for the potential negative effects of antipsychotic medications on bone mineral density, particularly in patients with additional risk factors for osteoporosis. Recommendations regarding routine monitoring of bone mineral density for patients prescribed antipsychotic medications cannot be made on the basis of existing evidence and more research is required. Is antipsychotic treatment linked to low bone mineral density and osteoporosis? A review of the evidence and the clinical implications
