Individuals in low‐income countries (“LICs”) often lack access to appropriate medicines. The multi‐disciplinary nature of this problem requires a holistic approach. Whereas, other writings on the topic tend to focus on one or a small number of issues, often from the perspective of a single discipline, this paper seeks to consider the major issues from a multi‐disciplinary perspective. It first considers mechanisms for improving the availability of medicines in LICs, through grants, prizes, treaties, advance market commitments, priority review and product development partnerships to incentivize and fund R&D for neglected diseases. The paper then assesses mechanisms for improving affordability of medicines in LICs, such as differential pricing mechanisms, monopsonies, patent law flexibilities and human rights obligations. Next, the paper reviews mechanisms for improving the efficacy of medicines in LICs, including authentication, criminalization, international and national enforcement and communication and education. Finally, the paper examines mechanisms for improving the obtainability of medicines in LICs, through low‐cost intervention, task‐shifting, efficient regulation, grass‐roots service provision and education. The paper concludes by identifying areas warranting further research.
