Use of antipsychotics in elderly patients with dementia: do atypical and conventional agents have a similar safety profile?

Pharmacological treatment of dementia addresses two main clinical features of the disease: cognitive deterioration with predominantly memory loss and behavioural and psychological symptoms (BPSD). While cholinesterase inhibitors are recommended in an attempt to delay memory loss and disability, what should be considered the most appropriate pharmacological treatment for BPSD has remained questionable. Antipsychotic medications, conventional and atypical agents, have been increasingly utilized in clinical practice but only a small number of clinical studies have investigated their relative cost-benefit ratio. This review focuses on the safety of atypical and conventional antipsychotics when used in patients with BPSD. Overall, atypical and conventional antipsychotics are associated with a similarly increased risk for all-cause mortality and cerebrovascular events. Relative to atypical agents users, patients being treated with conventional antipsychotics have an increased incidence of cardiac arrhythmias and extrapyramidal symptoms. Conversely, users of atypical antipsychotics are exposed to an increased risk of venous thromboembolism and aspiration pneumonia. Also, metabolic effects (i.e. increased risk of diabetes, weight gain) have consistently been documented in clinical studies with atypical antipsychotics, although this effect tends to be attenuated with advancing age and in elderly patients with dementia. Antipsychotics, both conventional and atypical, should be used with caution only when nonpharmacologic approaches have failed to adequately control BPSD. More effective interventions are necessary to improve postmarket drug safety in vulnerable populations

Risk of ischemic stroke associated with antidepressant drug use in elderly persons

Competing hypotheses have been formulated about a possible association between selective serotonin reuptake inhibitors (SSRIs) and ischemic stroke. However, the relationship between antidepressant drug use and ischemic stroke is still unclear. The aim of the study was to assess the association between the use of different types of antidepressants and the risk of ischemic stroke in elderly outpatients. A population-based, nested, case-control study was conducted in persons 65 years and older in the Integrated Primary Care Information database (1996-2005). Cases were all patients with a validated first ischemic stroke. Controls were matched on year of birth, sex, and index date. Exposure to antidepressants was divided in current, past, and nonuse and further categorized by type (SSRI, tricyclic, and other antidepressants), dose, and duration. Conditional logistic regression was used to compare the risk of ischemic stroke between users of antidepressants and nonusers. Overall, 996 incident ischemic strokes were identified. Current use of SSRIs was associated with a significantly increased risk as compared with nonuse (odds ratio, 1.55; 95% confidence interval, 1.07-2.25) in elderly patients, particularly when used for less than six months. No associations were observed for current use of tricyclic and other antidepressant drugs. To summarize, compared with nonuse, only SSRI use seems to be associated with an increased risk of ischemic stroke in elderly patients, particularly as a short-term effect

Association of community-acquired pneumonia with antipsychotic drug use in elderly patients: a nested case-control study

According to safety alerts from the U.S. Food and Drug Administration, pneumonia is one of the most frequently reported causes of death in elderly patients with dementia who are treated with antipsychotic drugs. However, epidemiologic evidence of the association between antipsychotic drug use and pneumonia is limited
