Background: Polypharmacy, the concurrent use of multiple medications by an individual, presents challenges in medication management, patient safety, and healthcare outcomes, particularly among older adults. In Saudi Arabia, the prevalence of polypharmacy is increasing due to the aging population and the burden of chronic diseases. Understanding healthcare providers' awareness and practices regarding medication switching is crucial for optimizing medication use and improving patient outcomes. Study Aim: This systematic review aims to synthesize and analyze existing literature on healthcare providers' awareness of medication switching for polypharmacy patients in Saudi Arabia. The study focuses on pharmacists and physicians, exploring their knowledge, attitudes, and practices related to medication management, deprescribing, pharmacovigilance, and Medication Therapy Management (MTM) services. Methodology: A systematic search was conducted across major databases, including PubMed, Scopus, and Google Scholar, using predefined search terms related to polypharmacy, medication switching, healthcare providers' awareness, and Saudi Arabia. Eligible studies were selected based on inclusion criteria, including study design, setting, participants, and relevance to the study aim. Data extraction and synthesis were performed to analyze key findings and themes related to healthcare providers' awareness of medication switching. Results: Six eligible studies were included in the systematic review, encompassing survey-based investigations, cross-sectional studies, and qualitative studies conducted in various healthcare settings across Saudi Arabia. The findings revealed gaps in pharmacists' and physicians' knowledge regarding Potentially Inappropriate Medications (PIMs), Drug-Drug Interactions (DDIs), pharmacovigilance practices, and deprescribing strategies. Recommendations for improving pharmacists' education, enhancing pharmacovigilance practices, and promoting collaborative care models were highlighted. Conclusion: Healthcare providers in Saudi Arabia demonstrate varying levels of awareness and practices regarding medication switching for polypharmacy patients. There is a need for targeted educational interventions, standardized pharmacovigilance practices, and collaborative efforts among healthcare providers to optimize medication use, reduce polypharmacy-related risks, and improve patient outcomes.
