WARNING
INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED
PSYCHOSIS — ELDERLY
PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS TREATED WITH ANTIPSYCHOTIC
DRUGS ARE AT AN
INCREASED RISK OF DEATH. ANALYSES OF SEVENTEEN PLACEBO-CONTROLLED
TRIALS (MODAL DURATION OF
10 WEEKS), LARGELY IN PATIENTS TAKING ATYPICAL ANTIPSYCHOTIC DRUGS,
REVEALED A RISK OF DEATH IN
DRUG-TREATED PATIENTS OF BETWEEN 1.6 TO 1.7 TIMES THE RISK OF DEATH IN
PLACEBO-TREATED
PATIENTS. OVER THE COURSE OF A TYPICAL 10 WEEK CONTROLLED TRIAL, THE
RATE OF DEATH IN DRUG-
TREATED PATIENTS WAS ABOUT 4.5%, COMPARED TO A RATE OF ABOUT 2.6% IN
THE PLACEBO GROUP.
ALTHOUGH THE CAUSES OF DEATH WERE VARIED, MOST OF THE DEATHS APPEARED
TO BE EITHER
CARDIOVASCULAR (E.G., HEART FAILURE, SUDDEN DEATH) OR INFECTIOUS
(E.G., PNEUMONIA) IN NATURE.
OBSERVATIONAL STUDIES SUGGEST THAT, SIMILAR TO ATYPICAL ANTIPSYCHOTIC
DRUGS, TREATMENT WITH
CONVENTIONAL ANTIPSYCHOTIC DRUGS MAY INCREASE MORTALITY. THE EXTENT TO
WHICH THE FINDINGS
OF INCREASED MORTALITY IN OBSERVATIONAL STUDIES MAY BE ATTRIBUTED TO
THE ANTIPSYCHOTIC DRUG
AS OPPOSED TO SOME CHARACTERISTIC(S) OF THE PATIENTS IS NOT CLEAR.
HALOPERIDOL INJECTION IS NOT
APPROVED FOR THE TREATMENT OF PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS
(SEE WARNINGS).
