ABSTRACT
BACKGROUND: Older patients with alcohol use disorder are at particular risk of developing adverse drug reactions due to multimorbidity, polypharmacy, and altered organ function.
OBJECTIVES: In this study, we investigated the frequency and characteristics of potentially serious alcohol-medication interactions, potentially inappropriate medications (PIMs) for older adults, and potential drug-drug interactions (pDDIs) in a population of older patients with alcohol use disorder over a 10-year period.
DESIGN: Retrospective monocentric cohort study.
METHODS: Prescribed medications were screened for potentially serious alcohol-medication interactions, PIMs, and pDDIs using the POSAMINO (POtentially Serious Alcohol-Medication INteractions in Older adults) criteria, the PRISCUS 2.0 list, the FORTA (Fit fOR The Aged) classification, and the drug interaction program AiDKlinik®.
RESULTS: We enrolled 114 patients aged ⩾65 years with alcohol use disorder, who were treated in an addiction unit of a university hospital in Germany. About 80.7% of the study population had at least one potentially serious alcohol-medication interaction. Potentially serious alcohol-medication interactions most commonly affected the cardiovascular (57.7%) and the central nervous system (32.3%). A total of 71.1% of the study population received at least one prescription of a FORTA C or D drug, compared with 42.1% who received at least one PIM prescription according to the PRISCUS 2.0 list. A total of 113 moderate and 72 severe pDDIs were identified in the study population.
CONCLUSION: Older patients with alcohol use disorders are frequently exposed to potentially serious alcohol-medication interactions, PIMs, and pDDIs. Improvements in the quality of prescribing should primarily target the use of cardiovascular and psychotropic drugs.
