摘要: BACKGROUNDAs rates of polypharmacy rise and medication regimens become more complex, the risk potential cytochrome P450 (CYP)–mediated drug-drug interactions (DDIs) is a growing clinical concern for older adults.objective: To determine prevalence CYP-mediated DDIs in hospitalized adults with analyze relationship between number drugs dispensed probability these this high-risk population.METHODSA prospective 16-week cohort study was conducted among consecutive new patients aged 65 years (>5 drugs) admitted to community hospital. The profiles were analyzed multidrug cytochrome-specific software program. determined, calculated as function medications using multivariate Poisson regression adjusted age sex. Comparative performance program an...
