Among Drugs Used to Calm Agitated Dementia Patients, Newer Drugs Seem Safer Than Older <\/p>\n
Feb. 23, 2012 -- The FDA has warned that treatment with antipsychotic drugs increases the risk of death among elderly patients with dementia, and now a new study confirms that some drugs are riskier than others. <\/p>\n
Compared to patients treated with the newer second-generation antipsychotic drug Risperdal (risperidone), patients who took the older, first-generation drug Haldol (haloperidol) had twice the risk of death. <\/p>\n
The study is by far the largest ever to examine death risk associated with antipsychotic drug use in patients with dementia. The drugs are often used to calm down dementia patients who can become agitated, sometimes to the point of violence. <\/p>\n
Researchers from Harvard Medical School reviewed data on more than 75,400 elderly residents of nursing homes in 45 states across the U.S. <\/p>\n
They conclude that certain antipsychotic medications may differ in the risk of death among the elderly with dementia. <\/p>\n
The study appears today in the journal BMJ. <\/p>\n
\u201cHaloperidol is not used as much as it once was in these patients, but it is still used,\u201d says researcher and Harvard Medical School instructor Krista Huybrechts, PhD. \u201cIt is clear that this drug carries an increased risk for death in elderly patients with dementia and should not be used.\u201d <\/p>\n
FDA Warning Prompted Study <\/p>\n
In 2005, the FDA warned that second-generation antipsychotic drugs, also known as atypical antipsychotics, were associated with an increased risk of death in older patients with Alzheimer\u2019s disease and other age-related dementias. <\/p>\n
In 2008, the warning was expanded to include conventional, first-generation antipsychotic drugs. <\/p>\n
Despite the safety concerns, both first- and second-generation antipsychotics are still prescribed for the treatment of agitated elderly dementia patients when non-medical interventions have failed, geriatrician Gisele Wolf-Klein, MD, tells WebMD. <\/p>\n
Wolf-Klein is director of geriatric education at the North Shore-LIJ Health System in New Hyde Park, N.Y. <\/p>\n
\u201cThere is a perception that nursing homes are putting patients on these drugs to keep them quiet, but that isn\u2019t the case,\u201d she says. \u201cWhen we prescribe these medications it is usually as a last resort.\u201d <\/p>\n
Death Risk Lowest in Seroquel Users <\/p>\n
The Harvard Study included elderly new users of antipsychotic drugs residing in nursing homes across the U.S. between 2001 and 2005. The antipsychotics evaluated in the study were Abilify, Geodon, Haldol, Risperdal, Seroquel, and Zyprexa. <\/p>\n
Among the major findings: <\/p>\n
Compared to Risperdal users, Haldol users were twice as likely to die from non-cancer-related causes during a six-month observation period, with the largest number of deaths occurring during the first 40 days of treatment. Users of the second-generation drug Seroquel (quetiapine) had a slightly lower risk for death than users of Risperdal. The death rate among users of Abilify (aripiprazole), Zyprexa (olanzapine), and Geodon (ziprasidone) was similar to that of patients who took Risperdal. <\/p>\n
The study is the first to suggest that Seroquel carries a lower risk for death than other second-generation antipsychotic drugs, and Huybrechts says more study is needed to confirm the finding. <\/p>\n<\/p>\n
