Summary
Selective serotonin reuptake inhibitors (SSRIs) increase fracture risk in older adults, with higher doses posing a greater danger. Lithium may offer protection against fractures, unlike other psychotropic medications.
Area of Science:
- Gerontology
- Psychopharmacology
- Epidemiology
Background:
- Psychotropic medications like SSRIs, benzodiazepines, and antipsychotics are linked to increased fracture risk in the elderly.
- Previous research indicates a potential association, but the magnitude and dose-response relationship require further clarification.
Purpose of the Study:
- To quantify the fracture risk associated with various psychotropic medications in older adults.
- To investigate the existence of a dose-effect relationship between psychotropic drug use and osteoporotic fractures.
Main Methods:
- A population-based study utilizing administrative databases in Manitoba (1996-2004).
- Inclusion of individuals aged 50 years and older, comparing osteoporotic fracture cases (n=15,792) with matched controls (n=47,289).
- Analysis of exposure to antidepressants (SSRIs vs. other monoamines), antipsychotics, lithium, and benzodiazepines.
Main Results:
- Selective serotonin reuptake inhibitors (SSRIs) showed the highest odds of osteoporotic fractures (OR=1.45).
- Other monoamine antidepressants (OR=1.15) and benzodiazepines (OR=1.10) were also associated with increased fracture risk.
- A dose-effect relationship was observed for SSRIs and benzodiazepines; lithium demonstrated a protective effect (OR=0.63).
Conclusions:
- SSRIs present a significant fracture risk in the elderly, potentially dose-dependent.
- Lithium appears to be protective against fractures in this population.
- Findings offer crucial insights for prescribing psychotropic medications in older adults to mitigate fracture risk.

01:24Drug Toxicity: Risk factors
Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...
01:15Drug Dosing: Geriatric Patients
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
01:27Pharmacodynamics in Geriatric Patients: Effects of Age
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
01:28Drug Therapy
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

01:29Psychological and Sociocultural Causes of Schizophrenia
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...
01:28Psychosis and Antipsychotic Drugs: Overview
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic symptoms in all...
