Xanax, a widely recognized medication for the management of panic attacks and anxiety disorders, is now available for purchase online through Canadian Drug Mart. This prescription medication, which contains the active ingredient alprazolam, belongs to the benzodiazepine class and works by enhancing the effects of a natural chemical in the body known as gamma-aminobutyric acid (GABA). By doing so, Xanax helps to calm the nervous system, providing relief from the overwhelming symptoms associated with panic attacks, such as rapid heartbeat, shortness of breath, and intense feelings of dread.
