title: Hyperprolactinemia and bone mineral density: the potential impact of antipsychotic agents.
abstract: The prevalence of schizophrenia is about 1% worldwide. Individuals with schizophrenia are at increased risk for osteoporosis and fractures for several reasons, including poor diet, lack of exercise, cigarette smoking, and polydipsia. Some antipsychotic medications may further increase the risk of fractures by causing dizziness, orthostatic hypotension, and falls. Studies in women with hyperprolactinemia resulting from pituitary tumors have demonstrated high rates of osteoporosis believed to result from hypoestrogenism. Similarly, hyperprolactinemia in men results in hypogonadism and bone loss. Preliminary surveys have indicated that schizophrenia patients also may have elevated rates of osteoporosis and pathological fractures, possibly resulting in part from the long-term administration of antipsychotic agents that produce hyperprolactinemia and secondarily lower estrogen and testosterone levels. This potential complication of treatment with certain antipsychotic agents requires careful study and could represent a serious public health problem.
