[Assessment of drug therapy in psychiatric elderly patients based on the AGS Beers criteria.].

The study objective was to analyze the frequency of prescription of potentially inappropriate medications (PIMs) to elderly patients treated in a psychiatric in-patient setting. This study was carried out using AGS Beers criteria, an anti-polypharmacy tool developed under the auspices of the American Geriatric Association. The study indicates a high frequency of use of PIMs from the following pharmacological groups: benzodiazepine derivatives, non-steroidal anti-inflammatory drugs (long-term use), as well as drugs with significant anticholinergic potential. The AGS Beers criteria can help optimize the treatment for older psychiatric patients and increase the safety of pharmacotherapy.
