Objective: The present study was conducted to evaluate the efficacy of Abana® (a poly-ingredient formulation with natural constituents) on in vitro platelet aggregation and occlusion-induced deep venous thrombosis in rats.
Methods: Anti-platelet property of Abana® was evaluated using ADP (Adenosin 5-diphosphate) and adrenaline-induced platelet aggregation models, and anti-thrombotic activity was evaluated against occlusion-induced deep venous thrombosis model in wistar rats.
Results: Under the in vitro conditions, Abana® (250, 500 and 1000 µg/ml) alleviated ADP and adrenaline-induced platelet aggregation in a dose-dependent manner. Abana® (1000 µg/ml) inhibited ADP and adrenaline-induced platelet aggregation by as much as 50.69% and 64.83% respectively. Furthermore, 6 days pre-treatment with Abana® (250 and 500 mg/kg, p.o.) in an in vivo study showed significant and dose-dependent protection against occlusion-induced deep venous thrombosis in rats.
Conclusion: These findings suggest that Abana®, a polyherbal formulation possesses anti-platelet and anti-thrombotic activities in the experimental models of in vitro platelet aggregation and in vivo deep venous thrombosis in rats.
