Alprazolam (trade name Xanax, available among other generic names) is a short-acting anxiolytic of the benzodiazepine class of psychoactive drugs. Alprazolam, like other benzodiazepines, binds to specific sites on the GABAA gamma-amino-butyric acid receptor.
Alprazolam has a fast onset of action and symptomatic relief. Ninety percent of peak benefits are achieved within the first hour (although onset may begin at 8–25 minutes of ingestion) of using either preparation for panic disorder, and full peak benefits are achieved in 1.5 and 1.6 hours respectively.
Alprazolam is classed as a high-potency benzodiazepine and is a triazolobenzodiazepine,namely a benzodiazepine with a triazole ring attached to its structure.
Clonazepam is a benzodiazepine drug having anxiolytic, anticonvulsant, muscle relaxant, sedative, and hypnotic properties.
Clonazepam has an unusually long elimination half-life of 18–50 hours, making it generally considered to be among the long-acting benzodiazepines.
Clonazepam, 5-(2-chlorphenyl)-1,3-dihydro-7-nitro-2H-1,4-benzodiazepine-2-one, is synthesized by following a standard scheme of making derivatives of 1,4-benzodiazepines, with the exception that the acceptor nitro group of the benzodiazepine system is introduced at the last stage of synthesis.
Both are correct! Xanax is short acting and onset is typically very fast. I used to take Xanax when I was suffering from a full on panic attack. Clonopin lasts longer & also takes longer to set in. I'm trying to make the switch from Xanax to Clonopin, so that my anxiety will be managed throughout the day, & I won't have to be in a full blown panic attack, just to take a xanax. Hope this helped you out a bit!
