The efficacy of clopidogrel therapy in patients with an acute coronary syndrome (ACS) has been established using the clopidogrel hydrogen sulfate (CHS) formulation. We compared the antiplatelet effectiveness of long-term administration of the original CHS with a generic clopidogrel besylate (CB) salt formulation in 86 patients with a history of an ACS. At 1 month after the episode, patients receiving 75 mg/d CHS were randomized to continue with CHS (n = 41) or to switch to 75 mg/d CB (n = 45). Platelet aggregation, vasodilator-stimulated phosphoprotein (VASP) phosphorylation, P-selectin expression, and platelet-leucocyte conjugates were determined before randomization and at 6 months afterward. No difference in any platelet parameter studied was observed between the 2 groups either before randomization or after 6 months of treatment with CHS or CB. We conclude that there is no difference in the antiplatelet efficacy between CB and CHS during long-term administration in patients with a history of an ACS.
