midazolam and Consciousness, Loss of

midazolam has been researched along with Consciousness, Loss of in 23 studies

Midazolam: A short-acting hypnotic-sedative drug with anxiolytic and amnestic properties. It is used in dentistry, cardiac surgery, endoscopic procedures, as preanesthetic medication, and as an adjunct to local anesthesia. The short duration and cardiorespiratory stability makes it useful in poor-risk, elderly, and cardiac patients. It is water-soluble at pH less than 4 and lipid-soluble at physiological pH.
midazolam : An imidazobenzodiazepine that is 4H-imidazo[1,5-a][1,4]benzodiazepine which is substituted by a methyl, 2-fluorophenyl and chloro groups at positions 1, 6 and 8, respectively.

( Haji, A; Ito, Y; Masuda, A; Shakunaga, K; Shibuya, N; Wakasugi, M, 1995)
