[Examination of the efficacy of clopidogrel-hydrogen-sulphate in patients with cerebrovascular disease]

SZAPÁRY László, FEHÉR Gergely

[INTRODUCTION - On the basis of current guidelines, acetylsalicylic acid plus dipyridamole or clopidogrel monotherapy should be used for the long-term treatment of patients with cerebrovascular disease, whereas acetylsalicylic acid monotherapy is not recommended. The efficiency of recently introduced generic clopidogrels has not been assessed in patients with a history of acute stroke. PATIENTS AND METHODS - 100 patients with a history of acute stroke or transient ischaemic attack were involved in our study. The patients received acetylsalicylic acid monotherapy in the first 48 hours, followed by clopidogrel-hydrogen sulphate (Egitromb®) monotherapy. The efficiency of the therapy was assessed on day 7 and 28 of medical therapy. RESULTS - At the first measurement (day 7) after clopidrogel-hydrogen sulphate treatment, the therapy seemed to be inefficient in 11 patients (11%). A strong, clinically significant correlation was found between blood pressure values, blood glucose and lipid parameters, hsCRP levels and platelet aggregation values. At the second measurement (day 28), an aggressive secondary preventive threapy resulted in the normalisation of the above mentioned parameters, and the efficiency of platelet aggregation inhibtion therapy was also improed, whereas no patients proved to be resistant. No unwanted events or haemorrhagic complications were registered. CONCLUSIONS - On the basis of the result of our study, treatment with clopidogrel- hydrogen sulphate is safe and efficient both clinically and on the basis of optical aggregometry. The significance of an aggressive secondary preventive therapy should be considered as a factor that might influence the efficiency of thrombocyte aggregation inhibitory therapy.]
