In Vitro Interaction Between Ticagrelor and Its Active Metabolite and Their Effects on Salicylic Acid

Asan Medical Center24 enrolled

Overview

This is a in-vitro study to evaluate the pharmacodynamic interaction between ticagrelor and its active metabolite (AR-C124910XX) and their effects on the pharmacodynamics of salicylic acid. The study consist of two parts of in-vitro study as follows; * Part 1 : in-vitro study to evaluate the pharmacodynamic interaction between ticagrelor and its active metabolite. Platelet aggregation tests with the agonist of adenosine diphosphate(ADP) will be assessed on the in-vitro mixtures of blank plasma and randomized paired concentrations of ticagrelor + AR-C124910XX. * Part 2 : in vitro study to evaluate the pharmacodynamic interaction between ticagrelor and its active metabolite. Platelet aggregation tests with the agonist of arachidonic acid will be assessed on the in-vitro mixtures of blank plasma plus randomized paired concentrations of ticagrelor and AR-C124910XX and the invitro mixtures with blank plasma and ticagrelor + AR-C124910XX + salicylic acid.

Outcomes

Primary Outcomes

Platelet aggregation(%) of the in vitro mixtures of blank plasma and drugs of the randomized paired concentrations

Plasma which were collected from healthy volunteers were used to make mixtures of drugs, ticagrelor, AR-C124910XX and salicylic acid. ADP and arachidonic acid were used as the agonists of platelet aggregation.

Time frame: The tolerability of volunteers after blood sampling will be followed for the duration of hospital stay, an expected average of 5 hours.
