title: Interactions between sodium salicylate and acetyl salicylic acid evaluated using ADP induced platelet aggregation and bleeding time.
abstract: 1 g acetyl salicylic acid orally significantly enhanced the initial rate of platelet aggregation induced by 1 mumol/l and 2.5 mumol/l ADP. Sodium salicylate was without effects on the platelet aggregation and specifically it did not prevent acetylsalicylic acid from inhibiting the secondary aggregation. Sodium salicylate was without effect on the bleeding time and did not inhibit the prolongation induced by acetyl salicylic acid. Our study does not lend support to the concept of an important interaction in vivo between acetyl salicylic acid and its first metabolite salicylate in man.
