    What are barbiturates?

    • Barbiturates were introduced in the early 1900s (for medical use) as sedatives, hypnotics, anesthetics and anticonvulsants.
    • These drugs cause depression (or slowing down) of the central nervous system (your brain and spinal cord).
    • There are four kinds of barbiturates:
      • "Ultra short-acting" barbiturates: Methohexital (Brevital), Thiamylal (Surital) and Thiopental (Pentothal).
      • "Short-acting" and "intermediate-acting" barbiturates: Pentobarbital (Nembutal) and Secobarbital (Amytal)
      • "Long-acting" barbiturates: Phenobarbital (Luminal) and Mephobarbital (Mebaral).

    What are the effects?

    • "Ultra short-acting" barbiturates produce anesthesia within one minute after intravenous use.
    • "Short-acting" and "intermediate-acting" barbiturates take effect within 15 to 40 minutes and last up to six hours. Used for sedation or to induce sleep.
    • "Long-acting" barbiturates take effect in an hour and last up to 12 hours. Used primarily for daytime sedation and the treatment of seizure disorders or mild anxiety.
    • The effects of all barbiturates resemble those of alcohol intoxication including:
      • Slurred speech.
      • Loss of motor coordination.
      • Impaired judgment.

    What are the dangers?

    • Physical dependence (aka: addiction).
    • Tolerance, which results in the need to take higher doses to get the same effect. These higher doses could be deadly and lead to an overdose.
    • Withdrawal from the use of depressants can lead to seizures, delirium and death.

    Are they addictive?

    Addiction rarely occurs among people who use a pain reliever, CNS depressant, or stimulant as prescribed; however, inappropriate use of prescription drugs can lead to addiction in some cases.
