摘要:1-(Lower)alkyl-4-(substituted)aminoalkylcarbonyl-1,4,9,10-tetrahydropy razolo[4,3-b][1,5]benzodiazepin-10-ones are useful, e.g., to protect warm blooded animals against the formation of gastric ulcers. They are active ingredients in otherwise conventional medicament compositions administered enterally or parenterally in standard dosage forms. Their synthesis, their novel intermediates and their acid-addition salts are described.
