Trends in polypharmacy and potential drug-drug interactions across educational groups in elderly patients in Sweden for the period 1992 2002

Abstract

This study indicates that the use of drugs, polypharmacy and potential DDIs have increased during 1992 to 2002 among the elderly. These changes were most prominent among the less educated women. Polypharmacy and potential DDIs represent potential health hazards for the elderly. Therefore, the trends of increasing polypharmacy and drug-drug interactions deserve attention and the mechanisms behind should be investigated further.
