Abstract: The primary aim of this research is to address the issue of pharmaceutical leftover medication. Within the pharmaceutical industry, the reverse supply chain (RSC) plays a pivotal role in enhancing profitability. RSC specifically focuses on the management of unused or leftover medications in the market, which can become hazardous once they expire. In this study, we present a comprehensive methodology for developing a research paper that introduces a theoretical model. This model is constructed through a synthesis of literature review findings, expert opinions, and the formulation of a mathematical framework. Our results yield a well-defined theoretical model designed to address the disposal of leftover medicines. In this context, we propose a new penalty ratio that involves consumer contributions, varying according to the extent of expired medication overstocking by the consumer. This mathematical model represents an enhancement of a previously proposed third-party logistics coordination model.

Keywords: pharmaceutical industries; supply chain; stochastic linear programming; drug recall.
