Interaction of salicylic acid with adenosine and adenosine triphosphate. Potential mechanism of intensifying acetylsalicylic acid-induced GI blood loss.
Complex formation between salicylic acid and adenosine or adenosine triphosphate in 0.2m phosphate buffer at pH=7 was investigated as a potential factor contributing to the prolongation of acetylsalicylic acid-induced GI blood loss. Spectrophotemetric techniques were used to evalute the complexation. Concerntration dependency of the absorbance decrease was measured at 27 and 37 degrees C. The addition of salicylic acid to either adenosine or adenosine triphosplate solutions appeared also to cause a decrease in surface tension which may play a role in reducing platelet aggregation induced by adenosine diphosphate. The results obtained seem to support the opinion that the mechansim of acetylsalicylic acid-induced GI blood loss is due to a combination of both local and systemic effect.
