Association between inherited CYP2D6/2C19 phenotypes and anticholinergic measures in elderly patients using anticholinergic drugs

Background: To compare measures of anticholinergic activity between metabolic phenotypes of the polymorphic enzymes cytochrome P450 2D6 (CYP2D6) and CYP2C19 in the elderly patients exposed to anticholinergic agents.; Methods: Long-term nursing home patients (n = 80) with an anticholinergic drug scale (ADS) score ≥3 were recruited from 22 nursing homes in Norway. Based on pharmacogenetic […]

Cognitive effects of reducing anticholinergic drug burden in a frail elderly population: a randomized controlled trial

Background: Observational studies report a relationship between anticholinergic drug scale (ADS) score and cognitive function. This study investigated whether a reduced ADS score improved cognitive function in a frail elderly population.; Methods: This randomized, controlled, single-blinded trial, recruited long-term residents with an ADS score of greater than or equal to 3 from 22 nursing homes […]
