Xanax
Trade name for alprazolam, a Schedule IV benzodiazepine anti-anxiolytic made by Pfizer. It is a fast-acting benzodiazepine.
Do not refer to the generic by the trade name. Note that the street drug, xannie, xanny, zanny, X, or Z is often fake alprazolam or alprazolam mixed with other drugs and should never be referred to as Xanax despite the play on the trade name.
