BACKGROUND: The simultaneous use of dementia medications and anticholinergic medications occurs frequently. Cholinesterase inhibitors and anticholinergic medications likely counteract one another, potentially exposing patients to medications with decreased benefit, more adverse effects, and higher cost of care. We identified the rate of concurrent prescriptions of cholinesterase inhibitors/memantine with anticholinergics in an urban hospital setting with a large Asian and Pacific Islander population.
METHODS: This study is a retrospective review of patients hospitalized from 1 January 2006 to 31 December 2010 at a general hospital who simultaneously received US Food and Drug Administration-approved dementia medications (galantamine, rivastigmine, donepezil, and/or memantine) and anticholinergics.
RESULTS: Overall, 304 patients receiving cholinesterase inhibitors/memantine also received anticholinergics. Of these patients, 64.1% were given high-potency anticholinergic medications, and 35.9% received medium-potency medications. Indications for the use of anticholinergic medication were urological (17.8%), gastrointestinal excluding nausea (32.6%), nausea (10.2%), psychiatric (7.9%), and other (31.6%). Asian patients received the combination of cholinesterase inhibitors/memantine and anticholinergics less frequently than Native Hawaiian or Caucasian patients (8.4% vs 12.2% and 13.3%, respectively; χ2 = 16.04, degrees of freedom = 2, P < 0.0003).
CONCLUSIONS: Simultaneous prescribing of cholinesterase inhibitors, memantine, and anticholinergic medications was significantly less common than in previous studies, with some ethnic variability. The less frequent occurrence of concurrent medications in the Asian population may be because of variations in the rate of indications or in tolerability for anticholinergic medications among the population.
