Definitions

• Thieno-triazolo-diazepines are known to be anxiolytic, muscle relaxant and anticonvulsant. These are compounds which are attached to the triazole ring, for example by alkyl (DT-OS 2405682), cycloalkyl (DBP 2435041), an oxygen-containing 5- or 6-membered ring (DT-AS 2445430) or a nitrogen or sulfur-containing 5- or 6-membered ring (DT-OS 2460776) are substituted.
• 8-bromo-6- (o-chlorophenyl) -1- [N- (2-hydroxyethyl) piperazinyl] -4H-s-triazolo [3,4c] thieno [2,3e] 1,4-diazepine Salts form and, in this form, have a water solubility of 0.5% which is important for the diazepine substance class.
