Best Antipsychotic for Geriatric Patients with Lower Risk of EPS

Comparison of Antipsychotics for Geriatric Patients

The American Academy of Family Physicians recommends Quetiapine as the preferred antipsychotic for geriatric patients when minimizing extrapyramidal symptoms (EPS) is a priority, with a recommended starting dose of 25mg (immediate release) orally 1
Aripiprazole is described as "less likely to cause EPS" but requires careful dosing (starting at 5mg) and has more potential drug interactions 1
Olanzapine (starting at 2.5-5mg) may cause drowsiness and orthostatic hypotension but has generally good tolerability in elderly patients, according to the American Academy of Family Physicians 2, 1
Risperidone has an "increased risk of EPS if dose exceeds 6mg/24h" and should be started at very low doses (0.25-0.5mg) in elderly patients, as recommended by the American Academy of Family Physicians 1, 3

From lowest to highest EPS risk in elderly patients, the hierarchy is: Quetiapine, Aripiprazole, Olanzapine, Risperidone, and Typical antipsychotics, with Quetiapine having the lowest risk of EPS among commonly used antipsychotics 1
Olanzapine has a moderate EPS risk, according to the American Academy of Family Physicians 2, 3
Risperidone has the highest EPS risk among atypicals, especially at doses >2mg, as reported by the American Academy of Family Physicians 2
Typical antipsychotics have the highest overall risk of EPS, according to the American Academy of Family Physicians 3

The recommended starting dose of Quetiapine is 25mg (immediate release) orally, every 12 hours if scheduled dosing is required, as recommended by the American Academy of Family Physicians 1
Dose reduction is required in elderly patients and those with hepatic impairment, according to the American Academy of Family Physicians 1
The maximum recommended dose of Quetiapine is generally 200mg twice daily, though lower doses are often effective in elderly patients 1

The American Academy of Family Physicians recommends monitoring for orthostatic hypotension, especially during initial dose titration, when using Quetiapine 1
Avoid combining Quetiapine with benzodiazepines when possible, as this increases sedation risk, as reported by the American Academy of Family Physicians 1

Elderly patients (>75 years) are less likely to respond to antipsychotics and more likely to experience side effects, making sulpiride a suitable option due to its lower incidence of extrapyramidal symptoms (EPS) 4

Typical antipsychotics should generally be avoided in elderly patients due to significant, often severe side effects involving the cholinergic, cardiovascular, and extrapyramidal systems, according to the American Academy of Family Physicians 5
Elderly patients have an inherent risk of developing irreversible tardive dyskinesia (up to 50% after 2 years of continuous use of typical antipsychotics), as reported by the American Academy of Family Physicians 5

Antipsychotics should be used at the lowest effective dose for the shortest possible duration in elderly patients, as recommended by the American Geriatrics Society 4
Behavioral interventions should be tried before pharmacological treatment whenever possible, according to the American Geriatrics Society 4
Daily evaluation with in-person examination is recommended when using any antipsychotic in elderly patients, as suggested by the American Geriatrics Society 4

Avoid medications that induce delirium in older adults, including anticholinergics, benzodiazepines, and sedative-hypnotics, as advised by the American Geriatrics Society 6, 7
