The invention relates to 1,5-dihydropyrrol-2-ones of Formula 1 which contain an aryl radical in the 1-position and a secondary amine radical in the 4-position, to a process for making and for a process to treat various forms of epilepsies and of states of anxiety and tension.

4-amino-1-aryl-1,5-dihydropyrrol-2-ones and process for making

The invention relates to the use of 2-amino-4-(4-fluorobenzylamino)-1-ethoxycarbonylaminobenzene of formula I ##STR1## or its pharmaceutically utilizable salts, for the prophylaxis and treatment of neuropathic pain.

Use of retigabine for the treatment of neuropathic pain

The invention relates to pyrazolo[3,4d]pyrimidin-4(5H)-ones and pyrazolo[3,4-d]pyrimidine-4(5H)-thiones and their tautomers and pharmaceutically acceptable salts, which contain a benzyl radical in the 2-position, processes for their preparation and their use as medicaments, in particular for the treatment of epilepsies of various forms and of allergic/asthmatic diseases.

Anticonvulsive and antiallergic/antiasthmatic

A process for the treatment of anxiety and tension, which comprises administering to a patient in need therefor an anxiolytically effective amount of a compound of the formula ##STR1## wherein X is hydrogen, a C.sub.1-4 alkyl, C.sub.1-4 alkoxy, trifluoromethyl residue, or halogen; R.sup.1 and R.sup.2 are independently of each other a C.sub.1-4 alkyl, cycloalkyl, C.sub.2-4 hydroxyalkyl, or heteroalkyl residue, or R.sup.1 and R.sup.2 together form a C.sub.2-6 alkylene residue in which one --CH.sub.2 -- group can be replaced by oxygen, nitrogen or sulfur; n is 0 or 1, and m is 0 or a cardinal number from 1-5, or a pharmaceutically acceptable salt of the compound.

For a process for treatment of anxiety and tension

The use of the compound I ##STR1## or its pharmaceutically utilizable salts for the propylaxis and treatment of the squelae of chronic reduced cerebral blood supply, in particular of stroke, and for the treatment of nuerodegenerative disorders is claimed.

Use of 2-4-amino-4-(4-fluorobenzylamino) (-1-ethoxy-carbonylaminobenzene

The use of the compound I ##STR1## or its pharmaceutically utilizable salts for the propylaxis and treatment of the sequel of chronic reduced cerebral blood supply, in particular of stroke, and for the treatment of neurodegenerative disorders is claimed.
