The term "potentially inappropriate medications" (PIM) refers to drugs thatare used among elderly patientsand should be avoided due to a significant risk of adverse reactions. Due to its high prevalence and related adverse effects including ADRs, morbidity, usage of healthcare services, and increased expenditures, the prescribing of inappropriate medication has become a major public health solicitude. Several PIM screening tools are anticipated to lower adverse drug reactions and promote rational drug use. The American Geriatrics Society (AGS) beers criteria, a Screening tool to alert to the right treatment (START), and a Screening tool for older people’s prescription (STOPP) are the criteria implemented to detect the PIMs. This study primarily focuses on the tools used in evaluating the PIM and the detailed information regarding the criteria.
