Word of the Day: Depressants

February 01, 2011

What’s the first thing you think of when you hear the word “depressants?” Maybe “depressed” or “sad?” But the drugs called depressants aren’t called that because they’re depressing in the emotional sense.

Depressants slow down (or “depress”) the normal activity that goes on in the brain. Alcohol is a depressant.

Doctors often prescribe central nervous system (CNS) depressants to patients who are anxious or can’t sleep. When used as directed, CNS depressants are safe and helpful for people who need them.

Types of CNS Depressants

CNS depressants can be divided into three main groups:

  • Barbiturates, which are used to treat some forms of epilepsy
  • Benzodiazepines (Valium, Xanax), which can be used to treat severe stress, panic attacks, convulsions, and sleep disorders
  • Sleep medications (Ambien, Sonata, Lunesta), which, as the name suggests, are used to help people with diagnosed sleep problems

How They Work

Most CNS depressants affect the brain in the same way—they enhance the activity of the gamma-aminobutyric acid (GABA). GABA is a neurotransmitter, one of the naturally occurring chemicals in the brain that sends messages between cells. GABA works by slowing down brain activity.

Although different classes of CNS depressants work in unique ways, they ultimately increase GABA activity, which produces a drowsy or calming effect.

Effects When Abused

CNS depressants can be addictive* and should be used only as prescribed. Otherwise, they can bring about major health problems, including addiction. Combining them with alcohol or other drugs like pain medications can lead to slowed breathing and heart rate, and even death.

(*Addiction is when a person compulsively seeks out the drug and cannot control their need for it, even in the face of negative consequences.)

Before using any types of depressant, there should always be a doctors approval to avoid any health problems or addictions.!

Wow i didnt realize how bad these really were. I always thouhght it was just something they teach to pass the time. Good thing i dont take.

OH MY

im emotional :(

This has touched me :)

The key to depression recovery is to start with a few small goals and slowly build from there. Draw upon whatever resources you have. You may not have much energy, but you probably have enough to take a short walk around the block or pick up the phone to call a loved one.

wow every thing yall said has touched me and i never did drugs but my friends

well the way i look at it is if the doctors say you have to take medication for your problems then take them if they dont then why take them you dont wanna have a chnce of ruining your life and messin you relationships up with your friends and family. its a waist of time takin and injecting your body with fluids or pills that can kill you and i dont think anyone is ready to go on. but for the people who do, do that please have some since to talk to a doctor before you do it. cause there could be a chance that you may miss cause your injecting your body with that stuff. you could have a good life just dont let the pills and fluids get to you.....

this is pretty nice to know all these stuff in my health class we are learning this stuff!!
