New pharmaceutical composition based on valproic acid and one of the pharmaceutically acceptable salts thereof, obtained by a new galenic preparation process which makes it possible to improve and simplify the galenic production, this composition also containing excipients which favorably modify its kinetics and its bioavailability.

Pharmaceutical composition based on valproic acid and a process for

Valproic acid preparations

This invention relates to new thieno [3,2-c] pyridine derivatives having the formula: ##STR1## in which: Y represents the OH group or an OR group in which R is a straight or branched lower alkyl radical, or Y represents a group ##STR2## in which R.sub.1 and R.sub.2 are each independently of each other, hydrogen or a straight or branched lower alkyl group; or R.sub.1 and R.sub.2 form together and with the nitrogen atom to which they are attached a heterocycle which may include a second heteroatom such as oxygen or nitrogen, wherein the latter may be substituted by a lower alkyl or benzyl radical which may be substituted; and X represents hydrogen, a halogen or a lower alkyl radical; and their addition salts with pharmaceutically acceptable mineral or organic acids if Y represents the group OR or ##STR3## or with mineral bases if Y represents OH, as well as the two enantiomers or their mixture. The invention also relates to the preparation process of new thieno [3,2-c] pyridine derivatives and to their therapeutic application as blood-platelet aggregation inhibiting agents and antithrombotics.
