The effects of three conventional antiplatelet regimes, dipyridamole 3 × 75 mg/day (D), sulfinpyrazone 4 × 200 mg/day (S), acetylsalicylic acid 3 × 330 mg/day combined with dipyridamole 3 × 75 mg/day (ASA + D), and very low dose acetysalicylic acid 100 mg/day (ASA) on platelet function were studied in man following 4 days of treatment. D and S slightly increased mean minimal ADP concentration for irreversible aggregation (n.s.), S reduced aggregation and thromboxane (TXB2) formation on low dose collagen (2P 0.05), ASA and ASA + D increased platelet count (2P 0.05), increased bleeding time (n.s. for ASA, 2P 0.05 for ASA + D), abolished irreversible aggregation on ADP, suppressed TXB2 formation on all (2P 0.001) and aggregation on lower concentrations of collagen (2P 0.01) and abolished aggregation and TXB2 formation on arachidonic acid (2P 0.001). Very low dose ASA suppresses platelet aggregation and TXB2 formation on several stimuli of possible physiologic significance. In the light of a recently proposed critical belance of vascular antiaggregatory prostacyclin and platelet proaggregatory TXA2 very low dose ASA might offer advantages over conventional dosage of ASA and should be evaluated in thromboembolic disorders. 相似文献

Summary Enteric-coated formulations of acetylsalicylic acid (ASA) should be advantageous in prophylaxis after stroke because they cause fewer gastrointestinal side effects. However, the absorption of unchanged ASA and the effectiveness of these formulations have been questioned, which prompted the present investigation. Fourteen elderly stroke patients on long-term medication with enteric-coated ASA 1.5 g daily and four patients on placebo were studied. When tested with arachidonic acid platelet aggregation was completely inhibited in all ASA subjects whereas it was normal in the controls. Plasma samples, drawn every 1/2 h for 6 h after tablet intake, were analyzed by HPLC. The presence of ASA was short lasting with a mean peak concentration of 55 µmol/l reached after 2–3.5 h. Salicylic acid (SA) appeared later, having a mean peak value of 591 µmol/l after 2.5–6 h. Thus, absorption of ASA as well as inhibition of platelet aggregation were confirmed during long-term medication with enteric-coated ASA. 相似文献

摘要: 目的 比较双重抗血小板聚集和单用药物治疗超敏 C 反应蛋白 (hs-CRP) <2 mg/L 的心绞痛患者的效果差异。方法 选取因心绞痛 6~48 h 内就诊于我院且 hs-CRP<2 mg/L 的患者 96 例, 采用随机数字表法分为阿司匹林组和联合治疗组, 每组 48 例。阿司匹林组患者口服拜阿司匹林 100 mg/d, 联合治疗组患者口服拜阿司匹林 10 mg/d 并加硫酸氢氯吡格雷片 75 mg/d, 治疗后 30 d 时对患者进行疗效评定, 并通过随访对患者 6 个月内出现复合终点事件的情况进行统计。结果 阿司匹林组总效率 [81.25% (39/48)] 与联合治疗组 [85.42% (41/48)] 差异无统计学意义 (χ2 =0.300, P>0.05)。2 组患者治疗后的复合终点事件差异均无统计学意义 (P > 0.05)。结论 对于 hs-CRP< mg/L 的心绞痛患者, 即心血管事件风险相对较小的患者, 单一与双重抗血小板聚集治疗方案的效果无明显差异。 相似文献

Summary We have studied the antiaggregatory effect of fenflumizole, a new non-steroidal antiinflammatory imidazole derivative, in ten patients with unstable angina pectoris.We have measured the aggregation induced by arachidonic acid (AA), ADP, and collagen, and serum or plasma concentrations of -thromboglobulin (-TG), platelet factor 4 (PF-4), thromboxane B2 (TXB2), and fenflumizole before, during, and after treatment with fenflumizole in two different regimens either as 10 mg b.i.d. for four days followed by 10 mg daily for six days (Group I,n=5), or as 20 mg b.i.d. for four days followed by 20 mg daily for six days (Group II,n=5).The threshold concentration of AA-induced platelet aggregation increased in both groups by the first day of treatment, the mean increase being significantly higher in Group II than in Group I. There was close correlation between serum fenflumizole and the threshold concentration of AA-induced platelet aggregation (r=0.95).A significant fall in TXB2 occurred in both groups. In group I TXB2 concentrations subsequently increased to initial values during treatment, whereas it remained significantly reduced in Group II. There were no significant changes in collagen and ADP aggregation, and -TG and PF-4 concentrations remained unchanged during and after the administration of fenflumizole. 相似文献

Summary The effect of 6 weeks of nifedipine 30–60 mg/d on platelet aggregation and lipid parameters has been studied.A diminution in ADP-, adrenaline- and collagen-induced aggregation was observed. In the case of adrenaline-and collagen-stimulated aggregation the decrease was statistically significant. It was found that platelets which aggregated markedly during the placebo treatment were most strongly inhibited by nifedipine. The changes in lipid parameters were not significantly correlated with changes in aggregation.This report is a part of a project realized within the frames of the government programme of studies of the side-effects of hypotensive drugs given for 1 year. 相似文献

Summary In 14 patients with coronary heart disease the effect of long-term treatment (mean 16 months, range 12–33) with alprenolol on platelet function and fibrinolytic activity was studied. While on the beta-blocker and two weeks after gradula withdrawal of it, the patients performed a bicycle-ergometer test and blood samples were obtained before and following exercise. Pre-exercise fibrinolytic activity, assessed by the euglobulin clot lysis time, was 183±27 min (mean ± SEM) while on alprenolol as compared to 111±18 min (p<0.01) after its withdrawal. Activation of fibrinolysis following exercise was not significantly influenced by alprenolol. In patients treated with alprenolol, the pre-exercise threshold level of ADP, producing platelet aggregation was 3.3 µM (geometric mean) and 5.1 µM after stopping treatment (p0.05). In patients receiving the beta-blocker, the ADP- threshold value dropped from 3.3 µM before exercise to 2.3 µM immediately after exercise (not significant). The corresponding values after withdrawal of alprenolol were 5.1 µM and 2.7 µM (p0.02). Adrenaline — stimulated aggregation was not significantly influenced by alprenolol. Serotonin release from platelets following maximal ADP- and adrenaline stimuli was not significantly changed by exercise in patients on beta-blockade. After stopping treatment, ADP-induced serotonin release was 22±4.1% before and 15±4.7% after exercise (p<0.02). The corresponding values using the adrenaline stimulus were 29±5.7% and 17±4.7% (p<0.05). It is suggested that during physical stress alprenolol may protect platelets against aggregatory stimuli. 相似文献
