Antibacterial Activity of Ticagrelor in Conventional Antiplatelet Dosages Against Antibiotic-Resistant Gram-Positive Bacteria

JAMA Cardiol. 2019 Jun 1;4(6):596-599. doi: 10.1001/jamacardio.2019.1189.

Abstract

This study uses in vitro assays and a mouse model to investigate antibacterial properties of ticagrelor to follow up findings from 2 clinical trials that showed patients taking ticagrelor for cardiovascular disease had a lower risk of infection-related death and improved lung function compared with patients treated with clopidogrel.
