Why the study?
Whether fentanyl can directly negate or reduce the inhibitory effect of P2Y12 receptor antagonists on platelet function had not been established.
Does fentanyl directly activate platelets, potentiate ADP response, or diminish sensitivity to prasugrel metabolite in healthy volunteer blood in vitro?
Population
Blood from healthy volunteers (19 women and 12 men; mean age 40 ± 13 years)
Comparison
Fentanyl at therapeutic and supratherapeutic concentrations under various experimental conditions
Design
In vitro laboratory study

No direct fentanyl effect on platelet activation or prasugrel metabolite sensitivity in vitro; leaves open absorption delay as sole mechanism for clinical P2Y12 interactions.
Does fentanyl directly activate platelets, potentiate ADP response, or diminish sensitivity to prasugrel metabolite in healthy volunteer blood in vitro?
Fentanyl does not directly impair platelet responsiveness to prasugrel metabolite in vitro, suggesting that delayed P2Y12 inhibitor effects in PCI patients are likely due to impaired intestinal absorption rather than direct platelet interactions.
