Dosis 100 mg atau 80 mg ASA selama ini merupakan dosis yang dianggap efektif untuk menginhibisi aggregasi trombosit. Walaupun begitu ada laporan yang menyebutkan dosis dibawah 80 mg juga cukup efektif untuk menekan aggregasi trombosit. Oleh karena itu penelitian ini ditujukan untuk membandingkan efek 50 mg dibandingkan 100 mg ASA. 18 sukareawan normal direkrut, aggregasi trombosit diukur sebelum dan setelah makan ASA; 3 hari setelah makan ASA; dan setelah washout 1 minggu darah diambil untuk test aggregasi trombosit setelah 3 hari makan 100 mg ASA. Tidak terlihat perbedaan yang bermakna pada aggregasi maksimum (Tmax) antara 50 mg(mean 28.33 + 13.62) dan 100 mg ASA (mean 14.9 + 14.04 ) (p> 0.05). Lag phase dan slope dari 50 mg dan 100 mg didapatkan perbedaan bermakna.(p< 0.05).
Kesimpulan : Tidak dijumpai perbedaan pada inhibisi aggregasi trombosit antara 50 dan 100 mg ASA. Dari hasil lag phase dan slope terlihat 100 mg ASA memberikan reaksi yang lebih cepat/ sensitif bagi inhibisi aggregasi trombosit, dan mungkin baik untuk digunakan sebagai loading dose. 100 mg and 80 mg of ASA have been known as the most effective dose for inhibiting platelet aggregation. There is evidence to suggest that ASA of less than 80 mg is still sufficient to inhibiting aggregation. Aim of this study is to investigate whether 50 mg ASA is as effective as 100 mg ASA. 18 normal volunteers were recruited, and the aggregation was measured before the patients take ASA; 3 days after taking 50 mg ASA; and after one week washed-out time, 3 days later after taking 100 mg ASA. The aggregation was tested: there was no statistical difference in the maximum aggregation (Tmax) between ASA; mean 28.33 + 13.62, and 14.9 +
Conclution: 14.04 (p> 0.05). Lag phase and slope showed significant difference between 50 mg and 100 mg (p< 0.05), which 100 mg showed a quick inbilition.
There was no difference in the inhibition of platelet aggregation between 50 mg and 100 mg ASA. From the results of the lag phase and the slope, it is avident that 100 mg ASA demonstrate a quick and sensitive response. In the inhibition of platelet aggregation, and it is likely that 100 mg is good for loading does
