[Oxprenol and platelet aggregation (author's transl)].

The effect on the platelet aggregation of the administration of 6 mg of oxprenolol has been studied in patients suffering from coronary artery disease. Four samples were collected: a control one, at the end, 1 and 5 hours after the end of the infusion. The aggregation has been induced both by ADP and adrenaline. The results are exposed and some pathogenetic hypotesis are suggested.
