Table 5 presents the ORs for hip/femur fracture see more according to the pharmacological profile of the antipsychotic in current use. The use of antipsychotics with high prolactin-raising properties LDN-193189 ic50 (i.e., most conventional antipsychotics and risperidone >4 mg/day) was associated with an increased risk of hip/femur fracture (ORadj 1.75 [95% CI 1.48, 2.08]), whereas antipsychotics with low prolactin-raising properties (i.e., most atypical antipsychotics including risperidone ≤4 mg/day) were not associated with an increased risk of fracture (ORadj 0.91 [95% CI 0.45, 1.85)]. After comparison of both groups, no significant difference was observed. Analysis stratifying current use according to the EPS properties of the antipsychotics suggested a trend towards increased risk with increasing EPS (ORadj 1.55 [95% CI 1.18, 2.04] for low EPS and ORadj 1.97 [95% CI 1.49, 2.61] for high EPS), but this trend did not reach statistical significance. There was no apparent association between the degree of potential orthostatic hypotensive or sedative side effects and
the risk of hip/femur fracture.
