[Effect of acetylsalicyclic and nicotinic acids and complamin on the formation of a prostacyclin-like substance by the aortic wall].
Experiments on Wistar rats have shown that single oral administration of acetylsalicylic (300 mg/kg), nicotinic (3 mg/kg) acids and complamin (2 mg/kg) inhibits platelet aggregation. It has been established that acetylsalicylic acid inhibits, as an antiaggregation agent, platelet aggregation and synthesis of a prostacycline-like substance by the aortal wall, and decreases its antiaggregation activity. Nicotinic acid and complamin inhibit platelet aggregation but do not lower antiaggregation activity of the aortal wall. Therefore, these latter drugs compare very favorably with acetylsalicylic acid as antiaggregation agents.
