Background

Nutritional status and eating behaviors play a significant role in the clinical effects of prescription drugs. Foods may alter the effect of drugs by interfering with pharmacokinetic processes. Pharmacodynamic mechanisms also may be involved in drug-food interactions and certain drugs can have significant effects on eating behaviors.

Objectives

This research—the Medication Safety Program—will be conducted in 3 phases. Phase I and II are subcontracted to MHA from MaGee Rehabilitation Hospital (Principle Investigator: Madelyn McGillin,MSN). Phase I will include a complete descriptive epidemiological study of the extent of risk for drug-food interactions among the elderly and will also examine the association of risk for drug-food interactions with clinical outcomes. Phase II of the study will assess the elderly's knowledge of drug-food risks and will also assess patient reports of outcomes associated with drug-food interactions. Phase III of the study will involve development of programs to reduce drug-food risks. The interventions will be targeted to prescribers, pharmacists, and high-risk elderly groups.
