Sir as one year has already passed post angioplasty, a single antiplatelet aspirin 75 mg would be enough and you don't need clopidogrel (as per standard America / European guidelines).  Still if you prefer clopidogrel this a clopidogrel carboxylate preparation is available, however I think the reaction might be due to clopidogrel compound itself rather than its salt.
