Ingredientes Farmacéuticos Activos Potencialmente Inapropiados en Adultos Mayores: Lista IFAsPIAM: Panel de Consenso Argentino.

Objectives: To perform a list agreed by Argentinean experts and adapted to the local context containing potentially inappropriate (PI) medications in old people (OP) usingthe Delphi consensus technique optimized for this subject.
Methods: A preliminary list of potentially inappropriate medications (PIM) was drawn up based on foreign PIM lists and a selective search in the scientific literature. The iterative Delphi process was used to submit the active pharmaceutical ingredients (APIs) of the preliminary PIM list to the panel of Argentinean experts. The analysis of theanswers to determine the arrival to the consensus was carried out applying three criteria specially defined for this purpose.
Results: After two Delphi rounds, it was not reached agreement about 12 APIs. The List of explicit criteria for PIAPIs for use in OP (IFAsPIAM List) was finally constituted by 128 APIs corresponding to 9 groups of the ATC classification system to which they were organized. In addition to each API, information justifying the unfavorable benefit/risk profile and therapeutic alternatives or recommendations/precautions was recorded. The group with the most PI APIs was N (NervousSystem) (60; 47%) followed by groups C (Cardiovascular) and M (Musculoskeletal).
Conclusion: This study presents the first Latin American list of PIM in OP developed using an expert consensus technique. The IFAs PIAM List would contribute to the rational use of drugs in elderly population, constituting a valuable tool in Argentinean public health.
