Antiplatelet drugs in the elderly: prescriptions often inappropriate and reduced tolerance by associated diseases and drugs

To assess the conditions of prescriptions and tolerance of antiplatelet drugs (APD) in the elderly and to detail the parameters that influence the tolerance of these drugs.

description To assess the conditions of prescriptions and tolerance of antiplatelet drugs (APD) in the elderly and to detail the parameters that influence the tolerance of these drugs. Prospective survey in a Department of Geriatric Medicine. Two hundred nineteen patients 70 years and older treated with one or two APD prior to admission were included during 7 months in 2008. We recorded the type of APD, associated diseases, main associated or co‐prescribed drugs which could interact with APD and the bleeding adverse events including cutaneous bleeding. The mean age of the 219 patients was 84.5 ± 6.7 years (70–101 years), women 59.4%. Among patients 64.8% received aspirin (mainly 75 mg), 28.3% received clopidogrel and 6.8% received their combination; 16.9% of prescriptions were off‐label; 51.6% of patients had an associated disease and/or an associated drug which could have increased risk of bleeding event. Among the patients who received a gastric‐protective drug, the prescription followed the recommendations of the French Health Authority in 38.9%. We recorded bleeding events in 24.2% of patients at admission and in 18.3% of patients during the hospitalization. Bleeding events were significantly more frequent in patients treated with aspirin than clopidogrel (40.8 vs. 24.2%, P
