Prevalence of Polypharmacy Among Patients with Chronic Liver Disease-A Narrative Literature Review.

Managing the therapy of patients with chronic liver diseases and comorbidities presents significant challenges for physicians and pharmacists, particularly regarding drug-induced liver damage and polypharmacy. Given the liver's central role in drug detoxification, polypharmacy in liver disease requires special attention. The aim of the review was to assess the prevalence of polypharmacy among patients with chronic liver diseases. A literature search focused on randomized controlled trials, database reviews, and medical records. Review of PubMed, SCOPUS, and ScienceDirect databases identified 2578 manuscripts, however only 11 studies met the inclusion criteria. The results of studies showed that the prevalence of polypharmacy among patients with chronic liver disease can exceed 50%, and can lead to high prevalence of MRP and pDDI among those patients. Findings reveal a critical link between polypharmacy and adverse outcomes in chronic liver diseases, including cirrhosis, hepatitis, and non-alcoholic fatty liver disease. Individualized treatment plans, considering factors such as age, gender, comorbidities, and liver disease severity are essential. The interventions focused on mitigating MRP and reducing pDDI need to be implemented in order to reduce the potential harm of polypharmacy.
