      abstract = {Free drug samples are widely used promotional tools in pharmaceutical marketing. Pharmaceutical companies distribute samples to physicians with the objective of increasing product familiarity, improving brand recognition, and influencing prescribing decisions. Although free samples may offer temporary benefits to patients by reducing immediate medication costs and enabling treatment initiation, concerns remain regarding their impact on rational prescribing, healthcare expenditure, patient safety, and medical ethics. This review paper examines the influence of free drug samples on physician prescription behavior through analysis of published literature, empirical studies, ethical discussions, and healthcare policy perspectives. The review highlights how free samples affect physician decision-making, increase preference for branded medications, reduce generic prescribing, and strengthen physician–pharmaceutical industry relationships. The paper also discusses the economic, ethical, and regulatory implications associated with sample distribution. Findings from multiple studies indicate that free samples significantly alter prescribing patterns, often favoring expensive branded medicines over cost-effective alternatives. Greater awareness, ethical guidelines, and transparent pharmaceutical marketing regulations are essential to ensure rational prescribing practices and patient-centered healthcare delivery. },
