Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
133 words
A method for the treatment of anxiety in a human or animal subject suffering from or susceptible to anxiety which comprises administering to the human or animal subject an effective amount for the treatment of anxiety in said subject of a compound of formula (II) ##STR6## wherein R 1 and R 2 independently represent hydrogen, halogen, C 1-4 alkoxy, hydroxy, amino, C 1-4 alkylamino, di(C 1-4 )alkylamino, mercapto or C 1-4 alkylthio; R 3 represents hydrogen, C 1-4 alkyl, C 3-5 alkenyl, aryl or aralkyl; R 4 represents hydrogen, C 1-7 alkyl, C 3-5 alkenyl or aralkyl; n is 2 or 3; the free valence is attached to either fused ring and the azabicyclic ring is in either the exo or endo configuration; or an acid addition salt or quaternary ammonium salt thereof.
