**1. Introduction**

Worldwide, the proportion of people>60 years of age is increasing faster than that of any other age group. Gender disparities, structural changes in the family and social environment, the number of older people living alone, changes in the burden of disease, drug therapy and the risk of disability, among other factors, indicate the importance of assessing the global health care and the specific problems of this population [1].

There are situations that can cause a worsening of the organic functional capacity of the elderly, such as: medications, illnesses, significant life changes, sudden increase in physical demands. Medications whose risk of adverse drug events (ADE) in the elderly or elderly exceeds expectations of clinical benefits compared to more effective, safe and available alternatives are called potentially inappropriate medications [2].

According to the WHO, quality of life is: "the perception that an individual has of his place in existence, in the context of the culture and value system in which he lives and in relation to his objectives, his expectations, his norms, their concerns. It is a very broad concept that is influenced in a complex way by the physical health of the subject, their psychological state, their level of independence, their social relationships, as well as their relationship with the essential elements of their environment " [3–5]. Due to the aforementioned in this work, the relationship that

exists between inappropriate medication and welfare states in the population over 65 years of age is explored.
