Tranquilizing drugs slow normal brain function. For that reason, they are often referred to as depressants. These kinds of drugs work by affecting the neurotransmitter gamma-aminobutyric acid (GABA). Neurotransmitters are brain chemicals that help brain cells communicate with one another by spreading nerve impulses from one nerve cell to another. The higher the level of GABA activity in the brain, the greater the calming effect produced. Tranquilizers are prescribed by doctors only and are usually dispensed as pills or capsules. Some types come in liquid or solution form.
Because tranquilizers slow down normal brain activity and produce a calming or drowsy effect, they are among the most common drugs prescribed to patients suffering from insomnia. Insomniacs are patients who either have trouble falling asleep or cannot fall asleep at all. Tranquilizers are also prescribed to patients diagnosed with anxiety, a type of mental disorder that causes extreme restlessness, uncontrollable feelings of fear, excessive worrying, and panic attacks. According to Jim Parker in Tranx: Minor Tranquilizers, Major Problems, about 70 million prescriptions for tranquilizers are written each year in the United States. Tranquilizers are also among the most commonly abused medications. In 2005, the National Center on Addiction and Substance Abuse (CASA) at Columbia University released a 214-page report titled "Under the Counter: The Diversion and Abuse of Controlled Prescription Drugs in the U.S." That report indicates that in 2003 nearly 6 million Americans abused prescription tranquilizers and sedatives.
