Comparison of antiplatelet activity of microencapsulated aspirin 162.5 mg (Caspac XL), with enteric coated aspirin 75 mg and 150 mg in patients with atherosclerosis

Abstract

The results show good inhibition of thromboxane B2 synthesis and subsequent platelet activity by all preparations of aspirin, although both microencapsulated aspirin 162.5 mg and aspirin EC 150 mg are slightly more effective than aspirin EC 75 mg. A randomised trial is now required to determine whether microencapsulated aspirin is associated with fewer gastric side-effects.
