ABSTRACT Our objective was to study the association between fracture risk and the use of anxiolytics and sedatives (benzodiazepines, etc.), neuroleptics and antidepressants.
This was a case control study. All cases consisted of subjects who had sustained a fracture during the year 2000 (n=124,655). For each case, three controls (n=373,962) matched for age and gender were randomly drawn from the background population. Exposure was defined as the use of neuroleptics, antidepressants and anxiolytics/sedatives, psychiatric disease (manic depressive states, schizophrenia, other psychoses), and other confounders. The effect of dose was examined as a defined daily dose per day (DDD/day). The values referred to are confounder-adjusted.
For anxiolytics and sedatives, there was a small increase in overall fracture risk (OR: around 1.1) even with limited doses (<0.1 DDD/day). No dose-response relationship was observed for anxiolytics and sedatives. For neuroleptics, a limited increase in overall fracture risk was observed (OR: around 1.2 from <0.05 DDD/day with no dose-response relationship). For antidepressants, a dose-response relationship was observed for fracture risk (OR: increasing from 1.15, 95% CI: 1.11-1.19 at <0.15 DDD/day to 1.40, 95% CI: 1.35-1.46 for >or=0.75 DDD/day). The risk of fracture was higher with selective serotonin re-uptake inhibitors than with tricyclic antidepressants.
Small increases in fracture risk were seen with the use of anxiolytics and sedatives and neuroleptics without a dose-response relationship. The increase may be linked to an increased risk of falls. For antidepressants, a dose-response relationship was found, with a higher fracture risk for selective serotonin re-uptake inhibitors.

    ABSTRACT: Serotonin plays a potential role in bone metabolism, but the nature and extent of this relationship is unclear and human studies directly addressing the skeletal effect of circulating serotonin are rare.

    ABSTRACT: Objective The aim of the study is to explore the incidence and the risks associated with major osteoporotic fractures, all-cause mortality with osteoporotic fractures and the effect of the psychiatric drug exposure in patients with schizophrenia during a 10-year follow-up period. Methods Two nationwide cohorts were selected from the Taiwan National Health Insurance Research Database (NHIRD) consisting of 30,335 patients with schizophrenia (age ≥ 40 years) and 121,340 age- and sex-matched control participants without schizophrenia. The psychiatric proportion of days covered (PDC) is an indicator of the intensity of drug exposure in patients with schizophrenia. The incidence and risk factors of major osteoporotic fractures were calculated for both cohorts. Additionally, the patient survival rate after major osteoporotic fractures was also calculated. Results During a 10-year follow-up period, 1677 (5.53%) schizophrenia and 4257 (3.51%) control subjects had major osteoporotic fractures (P < 0.001). The schizophrenia patients with a PDC > 0.1 showed a significantly higher incidence of major osteoporotic fractures than did the non-schizophrenia controls; however, those with a psychiatric PDC ≤ 0.1 did not. After adjustment, the psychiatric PDC was significantly and independently associated with the risk of major osteoporotic fractures except some medical morbidities but the schizophrenia diagnosis was not. In addition, among all 5934 patients with major osteoporotic fracture, the adjusted mortality hazard ratio for psychiatric PDC was 1.92 (95% CI = 1.63–2.26). Conclusions Patients with schizophrenia are at a higher risk for major osteoporotic fractures than the general population and also have a higher mortality rate due to major osteoporotic fractures. These findings may be caused by psychiatric drug use rather than schizophrenia, which suggests that directions can be taken in future studies.
