Drug Drug Interactions of Aspirin and P2Y12-inhibitors

March 23, 2017 updated by: Eva-Luise Hobl, Medical University of Vienna

Drug Drug Interactions of Antiplatelet Drugs and Morphine

Study Objective: To investigate potential drug-drug interactions (pharmacokinetics and pharmacodynamics) of morphine and antiplatelet drugs (aspirin, clopidogrel, prasugrel, ticagrelor)

Study Overview

Status

Completed

Conditions

Intervention / Treatment

Detailed Description

Rationale: Opiates reduce the intestinal resorption of orally administered drugs such as paracetamol. Because morphine is often injected to relieve pain in patients with myocardial infarction, it is of particular interest if morphine may decrease the rate of absorption of antiplatelet drugs. Results of this study will provide essential information for the use of morphine and antiplatelet drugs in clinical practice, in particular in myocardial infarction.
