Implication

Indobufen inhibits platelet function ex vivo in volunteers; hypothesis-generating for antithrombotic effects, requiring clinical outcome trials.

Structured PICO

Does indobufen inhibit platelet aggregation, the release reaction, and thromboxane B2 production in normal volunteers?

P
Population
8 normal volunteers evaluated for ex vivo effects of indobufen 2 hours after a 200 mg oral dose.
I
Intervention
Indobufen (in vitro: 10 microM and 100 microM; ex vivo: 200 mg oral single dose)
O
Outcome
Platelet aggregation, the release reaction, and thromboxane B2 (TxB2) productionsurrogate

Indobufen effectively inhibits platelet aggregation and the release reaction by blocking the platelet arachidonate pathway.

Cite This Study

Cattaneo et al. (2009) studied Healthy volunteers (n=8). Indobufen was evaluated on Platelet aggregation, release reaction and thromboxane B2 production. Indobufen (200 mg) completely inhibited secondary platelet aggregation, the release reaction, and thromboxane B2 production ex vivo in 8 normal volunteers.
