Inventor(s): Delbressine; Leonardus Petrus Carla (Nijmegen, NL), Wieringa; Johannes Hubertus (Heesch, NL)
Assignee: Akzo Noble N.V. (Arnhem, NL)
Application Number:08/693,064
Patent Claims: 1. A pharmaceutical composition comprising as a medicinally active compound: trans-5-chloro-2-methyl-2,3,3a, 12b-tetrahydro-1H-dibenz[2,3:6,7]oxepino[4,5-c]pyrrole or a pharmaceutically acceptable salt thereof; wherein the composition is a solid composition and disintegrates within 30 seconds in water at 37.degree. C.

2. The pharmaceutical composition of claim 1, wherein the composition further comprises a pharmaceutically acceptable water-soluble or water-dispersable carrier material.

3. The pharmaceutical composition of claim 2, wherein the carrier material is partially hydrolysed gelatin.

4. A method for treating tension, excitation, anxiety, and psychotic and schizophrenic disorders, comprising administering sublingually or buccally an effective amount of a pharmaceutical composition comprising trans-5-chloro-2-methyl-2,3,3a,12b-tetrahydro-1H-dibenz[2,3:6,7]oxepino[4, 5-c]pyrrole or a pharmaceutically acceptable salt thereof.

5. The pharmaceutical composition of claim 1, wherein the composition disintegrates within 10 seconds in water at 37.degree. C.

6. The composition of claim 1, further comprising one or more pharmaceutically acceptable auxiliaries selected from the group consisting of hydrolyzed dextran, dextrin, mannitol, algenates, polyvinyl alcohol, polyvinyl pyrrolidine and water soluble cellulose derivatives.

7. A pharmaceutical composition comprising trans-5-chloro-2-methyl-2,3,3a,12b-tetrahydro-1H-dibenz[2,3:6,7]oxepino[4, 5-c]pyrrole or a pharmaceutically acceptable salt thereof; and pharmaceutically acceptable auxiliaries, wherein the composition is made by the process of
