Antipsychotic Drugs: A New Risk Factor for Osteoporosis in Young Women With Schizophrenia?

O'Keane, Veronica, Meaney, Anna Maria·2005·Journal of Clinical Psychopharmacology

Abstract

Schizophrenic illness is associated with high rates of osteoporosis, the etiology of which remains obscure, but which may be at least partly explained by the prolactin-raising properties of antipsychotic medication. Conventional antipsychotics all cause hyperprolactinemia, whereas a limited number of atypical antipsychotic drugs do not. To investigate this further, we designed a cross-sectional comparison study between groups taking either prolactin-raising or prolactin-sparing antipsychotic medication. Participants were required to be premenopausal women with a diagnosis of schizophrenia, and to have received exclusively either prolactin-raising (n = 26), or olanzapine (n = 12) antipsychotic medication. Half of the subjects in the prolactin-raising group were being treated with conventional (n = 13), and half with newer "atypical," antipsychotic drugs (n = 13). Subjects had lumbar spine and hip bone mineral density (BMD) evaluated by a dual-energy x-ray absorptiometer (DEXA) scan. A blood sample was taken to measure prolactin and sex hormone axis measures. The results demonstrated that the group taking prolactin-raising medication had higher rates of bone pathology, compared with the olanzapine group. High prolactin levels were related to measures of hypogonadism and low BMD values. Within the prolactin-raising group, those taking newer atypical compounds had higher levels of prolactin, lower levels of sex hormones, and lower BMD values than the group taking conventional antipsychotic medication. These findings suggest that the high rates of osteoporosis associated with schizophrenia may result from hypogonadism secondary to antipsychotic-induced hyperprolactinemia, and that the prolactin-raising profile of antipsychotic drugs should be considered when choosing an antipsychotic drug.

  • Some studies found a relationship between the use of prolactin-raising medication and low bone mineral density in patients with chronic schizophrenia, while others failed to find a relationship between prolactin, antipsychotics and osteoporosis.

    “Some studies (490-493) found a relationship between the use of prolactin-raising medication and low BMD in patients with chronic schizophrenia, while others (474,489,494-498) failed to find a relationship between prolactin, AP and osteoporosis.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
