SALT OF A SULFONIC ACID CONTAINING CLOPIDOGREL AND USE THEREOF FOR THE PRODUCTION OF PHARMACEUTICAL FORMULATIONS

摘要

Clopidogrel benzenesulfonate salt (I) which is either at least partly in crystalline form or is produced by precipitation from a solution of clopidogrel in toluene and/or dioxane, is new. Independent claims are also included for: (1) production of (I) by precipitation from a solution of clopidogrel in toluene and/or dioxane; (2) purifying clopidogrel by converting impure clopidogrel or a salt thereof to (I) and optionally releasing clopidogrel base from the isolated (I) and optionally converting it to another salt; (3) particles comprising (I) adsorbed on a solid adsorbent; (4) production of the particles by recovering them from a solvent in which the adsorbent in insoluble and (I) is soluble. ACTIVITY : Anticoagulant; Cerebroprotective; Cardiant. MECHANISM OF ACTION : Platelet aggregation inhibitor.
