[Treatment with indobufen of platelet hyperaggregation in a group of patients with vascular diseases]

Twenty-five patients with enhanced spontaneous platelet aggregation and impaired arterial or venous circulation syndromes have been treated by indobufen. Each of them received, by oral administration, 200 mg of the drug twice a day for periods of time from fifty one to hundred eleven days. This treatment normalized, in all the cases, the platelet aggregation. In eight patients of the group, three hours after the last drug administration, the average of the maximum platelet aggregation curves deflections, induced by ADP, epinephrine, ristocetin and collagen, resulted significantly reduced, while, in seven other patients, twelve hours after the last drug administration, only the aggregation curves induced by ADP and epinephrine resulted significantly inhibited. Most on the patients with arterial impairment syndromes noticed some improvements of their symptoms. Also the patients with light subjective post-phlebitic symptoms declared to feel better. The drug has been well tolerated. Therefore, its use is recommendable whenever it is advisable to get a full antiplatelet effect whose the prompt reversion might be required.
