title: [The effects of ticlopidine and nifedipine on platelet aggregation in patients with obliterating arteriopathy of the lower limbs].
abstract: This paper evaluates the antiaggregant action of ticlopidine and nifedipine in patients with obliterate arteriopathy in inferior limbs of arteriosclerotic etiology (OAIL). They were established 4 study groups: control, with health volunteers without treatment (N = 10); patients treated with placebo (n = 11); patients treated with 500 mg/day of ticlopidine (n = 12) and treated with 30 mg/day of nifedipine (n = 12). The last 3 groups the treatment duration was 30 days. It was studied the platelet aggregatory activity against ADP and collagen, before drug administration and at 15 and 30 days post-treatment. Our results suggest that: Platelet aggregation is increased in patients with AOMI compared with that observed in the control group. Ticlopidine inhibits platelet aggregation induced by ADP, but not that induced by collagen. Nifedipine doesn't produce any effect on platelet aggregation.
