Harm Reduction
When on high doses of benzodiazepines, users are likely to black out and potentially hurt themselves through a variety of adventures. If you are using it as a sleep aid, it's reccomended to continue doing what you're doing until you begin to feel drowsy, then go to bed
Some users report Alprazolam (And benzodiazepines in general) to compulsive redosing, trying to find a “high” which is where a fair amount of the above point comes from. To avoid this keep doses low and be wary of reduced inhibitions while under the influence of Alprazolam
Interactions
As with other depressants, Alprazolam should not be combined with any other CNS depressants (such as Alcohol), at the risk of respiratory depression, which can lead to death. See the Drug combinations chart for more information.
Chemistry and Pharmacology
Alprazolam is absorbed fairly rapidly, with peak plasma levels achieved around the one-two hour mark.
It is primarily metabilised via CYP3A4. Alprazolam is a chemical analogue of triazolam. It is a triazolobenzodiazepine. It binds to the GABA(a) receptor and modulates the function of the GABA receptor. You can learn more about the GABA(a) receptor here. [url][[1]][/url]
