The correct answer is A.
The Beers criteria were first drawn up in 1991 and were last updated by an expert panel of the American Geriatrics Society in 2015. The criteria consist of a list of recommendations regarding potentially inappropriate medication use and use of alternative medications in older adults aged 65 and over.
This group is at increased risk for adverse effects from medications (especially neurological adverse effects). The rationale of the guidelines is to decrease unnecessary prescriptions, with the goal of decreasing polypharmacy, drug-drug interactions, and drug reactions.
