Abstract (en)

[origin: WO9854186A1] The invention is a salt of the CNS-depressant trans-5- chloro-2,3,3a,12b-tetrahydro-2- methyl-1H-dibenz[2,3:6,7] oxepino[4,5-c]pyrrole and a salt-forming agent, the latter being an aromatic sulphonic acid. The disclosed salt, preferably the besylate, has favourable properties. Thus it has the required insolubility and crytallinity in order to be suitable for use in depot injection preparations.
