Drug access refers to the ability of individuals to obtain, afford, and use necessary medications for their health and well-being. This research area focuses on understanding and addressing the barriers that prevent people from accessing essential drugs, such as high costs, lack of insurance coverage, limited availability, and logistical challenges. Researchers in this field seek to identify strategies to improve drug access, such as increasing affordability, expanding insurance coverage, improving distribution systems, and increasing awareness of available resources. By addressing these barriers, researchers aim to ensure that all individuals can access the medications they need to maintain their health and quality of life.
