Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
A method of treatment of depression which comprises administering to a human or animal subject suffering from depression an effective amount for the treatment of depression of a compound of formula (1): ##STR12## wherein R 1 and R 2 independently represent hydrogen, halogen, C 1-4 alkyl, 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.
Claim 2
Independent Claim
123 words
A method of treatment of depression which comprises administering to a human or animal subject suffering from depression an effective amount for the treatment of depression of a compound of formula (1): ##STR12## wherein R 1 and R 2 independently represent hydrogen, halogen, C 1-4 alkyl, 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.
Claim 3
Dependent Claim
25 words
A method according to claim 1 wherein the compound of formula (i) is (3 α-tropanyl)-1H-indole-3-carboxylic acid ester or a physiologically acceptable salt or solvate thereof.
Claim 4
Dependent Claim
69 words
A method according to claim 1 in which the compound is a compound of formula (i) wherein R 1 and R 2 indpendently represent hydrogen, halogen or C 1-4 alkyl; R 3 represents hydrogen or C C 1-4 alkyl; R 4 represents hydrogen, C 1-7 alkyl or aralkyl; the carbonyl group is attached to the 3-position of the indole ring, and the azabicyclic ring is in the endo configuration.
Claim 5
Dependent Claim
30 words
A method according to claim 1, wherein said compound of formula (i) is administered in a dose of 0.5 μg to 20 mg from 1 to 4 times per day.
Claim 6
Dependent Claim
30 words
A method according to claim 1 wherein said compound of formula (i) is administered in a dose of 0.05 mg to 10 mg from 1 to 4 times per day.
