Stomach Meds May Impair Cognition

pillsA common class of medication used to block stomach acid may be associated with cognitive impairment in older African-American adults.

A new study finds that long-term use of medication such as Axid, Pepcid, Tagamet and Zantac may increase the risk for showing signs of cognitive impairment by 2.5 times.

The medications are called histamine2 receptor antagonists (H2A) and are among the most popular medications prescribed in the United States.

More than 16 million prescriptions were dispensed in 2005 and several of these medications are also available over-the-counter to treat ulcers, acid reflux and other gastrointestinal disorders.

The is study published in the August issue of the Journal of the American Geriatrics Society.

These acid blockers, including ranitidine and famotidine, are among the most popular medications prescribed in the United States. More than 16 million prescriptions were dispensed in 2005 and several of these medications are also available over-the-counter.

The five-year observational study included 1,558 cognitively normal African-Americans aged 65 and older. After controlling for other possible factors, nearly 18 percent of H2A users studied exhibited signs of cognitive impairment.

“Taking these medications continuously appears to put older African-Americans at greater risk for the development of cognitive impairment,” said Malaz Boustani, M.D., MPH, assistant professor of medicine at the IU School of Medicine and a Regenstrief research scientist.

Dr. Boustani is lead author of the study. “We need to study this further to determine how acid blockers might be causing or creating this effect and if it occurs only in African-Americans.”
