Definitions
- the present invention relates to a new polymorph of clopidogrel hydrogen sulfate or (+) - (S) - ⁇ - (2-chlorophenyl) -4,5,6,7-tetrahydrothieno [3,2-c] pyridinyl- hydrogen sulfate 5-methyl acetate and a process for its preparation. More particularly, the invention relates to the preparation of this polymorph called Form 2 and to the isolation of this compound in this new crystalline form, as well as to the pharmaceutical compositions containing it.
- Clopidogrel hydrogen sulfate is an antithrombotic agent which was first described in EP 281459.
- the synthetic process claimed in this patent allows the preparation of clopidogrel hydrogen sulfate which will be called Form 1. It has now been discovered that clopidogrel hydrogen sulfate can exist in different polymorphic crystalline forms which differ from each other by their stability, by their physical properties, by their spectral characteristics and by their process of preparation. Thus one of these new polymorphic forms forms the subject of the present invention, it is described in the present application and will be named Form 2.
- Patent EP 281459 describes enantiomers of tetrahydrothienopyridine derivatives and their pharmaceutically acceptable salts.
- EP 281459 specifically claims clopidogrel hydrogen sulfate, that is to say the dextrorotatory isomer, which has excellent anti-platelet aggregation activity while the levorotatory isomer is less active and less well tolerated.
- Patent EP 281459 filed ten years ago makes no reference to the existence of specific polymorphic forms of clopidogrel hydrogen sulfate.
- EP 281459 allows the preparation of the hydrogen sulfate of the polymorph of clopidogrel Form 1.
- EP 281459 also does not suggest the existence of different polymorphic forms of clopidogrel or of the hydrogen sulfate of clopidogrel.
- the dextrorotatory isomer of clopidogrel is prepared by salification of the racemic compound with an optically active acid such as 10-L-camphosulfonic acid in acetone followed by successive recrystallizations of the salt up to obtaining a product with constant rotary power, then liberation of the dextrorotatory isomer from its salt by a base.
- the synthesis methods described in the prior art only allow the synthesis of clopidogrel hydrogen sulfate Form 1.
- the present invention relates to the polymorphic form called Form 2 of clopidogrel hydrogen sulfate, which like Form 1 of this compound is useful as a drug for the prophylaxis and treatment of thrombosis by acting as an antiplatelet agent.
- Form 2 of clopidogrel hydrogen sulfate which like Form 1 of this compound is useful as a drug for the prophylaxis and treatment of thrombosis by acting as an antiplatelet agent.
- the polymorphic Form 2 of clopidogrel hydrogen sulfate is therefore used as active ingredient for the preparation of a medicament, in combination with at least one pharmaceutically acceptable excipient, in the same indications as Form 1.
- Form 2 a new, very stable crystalline form having a well defined structure, hereinafter referred to as Form 2. More particularly, it has been found that the new crystalline form of clopidogrel hydrogen sulfate, Form 2 is at least as stable as the Form 1 described and that it does not transform spontaneously in Form 1 previously known. In addition, the powder obtained from Form 2 is more compact and much less electrostatic than that obtained from Form 1 and can therefore be more easily subjected to any treatment under the usual conditions of pharmaceutical technique and in particular galenic industrial. It has also been found that Form 2 has a lower solubility than Form 1 resulting from its greater thermodynamic stability.
- FIG. 6 shows the spatial conformation of clopidogrel Form 2 hydrogen sulfate
- FIG. 7 shows the stacking of Clopidogrel Form 2 hydrogen molecules in the crystal mesh. It has been found from crystallographic data that the crystal structure of Form 1 contains two free cations in the crystal of clopidogrel and two free bisulfate anions. The two free cations are of similar conformation. According to the crystallographic data of Form 2, it was found that it contains a free cation in the crystal - anion bisulfate pair.
- the arrangement of the anions is very different from one to the other of the two crystal structures.
- the crystal structure of Form 2, of orthorhombic type is less dense (1, 462 g / cm 3 ) than the crystal structure of Form 1, of monoclinic type, (1, 505 g / cm 3 ).
- the present invention relates to a process for the preparation of Form 2 of clopidogrel hydrogen sulfate, characterized in that:
- camphosulfonate (a) methyl (+) - (S) - ⁇ - (2-chlorophenyl) -4,5,6,7- tetrahydrothieno [3,2-c] pyridinyl-5-acetate camphosulfonate is dissolved in an organic solvent, (b) the camphosulfonic acid is extracted with an alkaline aqueous solution of potassium carbonate and washed with water,
- the present invention relates to a process for the preparation of (+) - (S) clopidogrel hydrogen sulfate Form 2, characterized in that: the hydroacetonic mother liquors resulting from the crystallization of Form 1 of the (+) - (S ) clopidogrel hydrogen sulfate will eventually release crystals of clopidogrel Form 2 after 3 to 6 months.
- hydroacetonic mother liquors resulting from the crystallization of Form 1 of (+) - (S) clopidogrel hydrogen sulphate contain 0.3 to 1% water. They contain up to about 10% clopidogrel hydrogen sulfate, this amount being calculated from the amount of camphosulfonate (+) - (S) - ⁇ - (2-chlorophenyl) -4,5,6,7-tetrahydrothieno [3,2-c] methyl pyridinyl-5-acetate used during the transformation into hydrogen sulphate.
- the present invention relates to another process for the preparation of Form 2 of clopidogrel hydrogen sulfate, characterized in that:
- camphosulfonate (a) methyl (+) - (S) - ⁇ - (2-chlorophenyl) -4,5,6,7- tetrahydrothieno [3,2-c] pyridinyl-5-acetate camphosulfonate is dissolved in an organic solvent, (b) the camphosulfonic acid is extracted with an alkaline aqueous solution of potassium carbonate and washed with water,
- the subject of the present invention is Form 2 of clopidogrel hydrogen sulfate, characterized by the X-ray diffraction profile of the powder given in TABLE I.
- Form 2 is also characterized by a melting point, determined by differential enthalpy analysis (DSC), of 176 ° C and by characteristic absorptions in the infrared and in the near infrared.
- DSC differential enthalpy analysis
- d is the inter-reticular distance and I / Io represents the relative intensity, expressed as a percentage of the most intense line.
- DSC Differential enthalpy analysis
- Form 2 has characteristic absorptions at 2551 cm “1 , 1497 cm “ 1 , 1189 cm “1 and 1029 cm “ 1 which are absent from Form 1.
- the particular structure of the powder in Form 2 was highlighted by an analysis of the single crystal by X-ray diffraction of the powder using an MSC-Rigaka AFC6S diffractometer and the SHELXS-90 and SHELXS-93 software on a SG IRIS Indigo workstation.
- the position of CH hydrogens was generated at a distance of 0.95A.
- the crystallographic data in particular the interplanar distances (a, b, c) the angles ( ⁇ , ⁇ , ⁇ ) and the volume of each unit cell, are indicated in TABLE V.
- the angles are in degrees.
- the estimated standard deviations to the last decimal place are in parentheses.
- the angles are in degrees.
- the estimated standard deviations to the last decimal place are in parentheses.
- the Form 1 crystals are in the form of irregular plates, while the Form 2 crystals are in the form of agglomerates. Thanks to its low electrostaticity compared to that of Form 1, it is therefore particularly suitable for the manufacture of pharmaceutical compositions for the treatment of all diseases in which an antithrombotic is indicated.
