Applications A metabolite of Flunitrazepam (F500700). References Asai, H., et al.: J. Pharmacol. Exp. Ther., 277, 1004 (1996), Kilicarslan, T., et al.: Drug Metab. Dispos., 29, 460 (2001), Tanaka, E., et al.: J. Toxicol. Clin. Toxicol., 40, 69 (2002),

Applications A new benzodiazepine derivative as a new anti-anxiety drug. Ethyl Loflazepate and its metabolite were compared with those of Diazepam (D416855), Nitrazepam (N490140) and Lorazepam (L469850). The anticonflict effect of Ethyl Loflazepate was slightly more potent than that of Diazepam and much more potent than that of Lorazepam. Controlled substance. References Cano J.P., et al.: J.

Applications Labelled Flurazepam (F500800). Flurazepam is used as an sedative, hypnotic. This is a controlled substance (depressant). References Sternbach, L.H., et al.: J. Med.

Applications A metabolite of Midazolam (M343000).

Applications Flubromazolam is an analog of flubromazepam (F418600). Flubromazepam is a designer benzodiazepine drug structurally related to Phenazepam (P295300); a drug used in the treatment of neurological disorders such as epilepsy, alcohol withdrawal and insomnia. Phenazepam (P295300) can also be used as a premedication before surgery as it augments the effects of anesthetics and reduces anxiety. References Moosmann, B., et al.: J.
