Triazolam

Summary
Triazolam, sold under the brand name Halcion among others, is a central nervous system (CNS) depressant tranquilizer of the triazolobenzodiazepine (TBZD) class, which are benzodiazepine (BZD) derivatives. It possesses pharmacological properties similar to those of other benzodiazepines, but it is generally only used as a sedative to treat severe insomnia. In addition to the hypnotic properties, triazolam's amnesic, anxiolytic, sedative, anticonvulsant, and muscle relaxant properties are pronounced as well. Triazolam was initially patented in 1970 and went on sale in the United States in 1982. In 2017, it was the 289th most commonly prescribed medication in the United States, with more than one million prescriptions. Triazolam is usually used for short-term treatment of acute insomnia and circadian rhythm sleep disorders, including jet lag. It is an ideal benzodiazepine for this use because of its fast onset of action and short half-life. It puts a person to sleep for about 1.5 hours, allowing its user to avoid morning drowsiness. Triazolam is also sometimes used as an adjuvant in medical procedures requiring anesthesia or to reduce anxiety during brief events, such as MRI scans and nonsurgical dental procedures. Triazolam is ineffective in maintaining sleep, however, due to its short half-life, with quazepam showing superiority. Triazolam is frequently prescribed as a sleep aid for passengers travelling on short- to medium-duration flights. If this use is contemplated, the user avoiding the consumption of alcoholic beverages is especially important, as is trying a ground-based "rehearsal" of the medication to ensure that the side effects and potency of this medication are understood by the user prior to using it in a relatively more public environment (as disinhibition can be a common side effect, with potentially severe consequences). Triazolam causes anterograde amnesia, which is why so many dentists administer it to patients undergoing even minor dental procedures. This practice is known as sedation dentistry.
