barbituates
These drugs act to depress the central nervous system and are often called sleeping pills. They are derived from barbituric acid (C4H4N2O3), a combination of urea and malonic acid. Depressants act as downers, and can slow the body and mind down. There are over 2000 known barbiturates. They are some of the most addictive drugs. They are often a substitute for alcohol (similar affects are produced). People use barbiturates to get a sense of euphoria and relaxation. It's illegal to take barbiturates without a doctor's prescription and supervision.Barbs, downers, sleepers, stumblers, blues, ye
Barbiturates may also increase the flow of chloride ions across the neuronal membrane. Also, since barbiturates dissolve into body fat, they can accumulate and then later re-enter the blood stream. In higher doses: barbiturates can actually increase some types of behavior and act like a stimulant. These effects may be caused by depressing inhibitory brain circuits. A major problem with barbiturates is that they may lead to tolerance and dependence. llow jackets, purple hearts, red dolls, rainbows, tootsies, blue angelsSHORT TERM EFFECTS:* relief of tension and anxiety* sleepiness* feeling of drunkness/intoxication* slurred speech* inability to control simple body functions (walking, balance, etc. EFFECTS ON THE BRAIN:Barbiturates dissolve easily in fat. Barbiturate overdoses may occur because the effective dose of the drug is not too far away from the lethal dose. They are sometimes made into powders for injection. In other words, barbiturates at these doses act to remove inhibitory behavior. Because sodium ions cannot flow across the neuronal membrane, action potentials, cannot be produced. The effect of increased chloride ion flow would be to reduce the chance of an action potential being generated. Because of this property, barbiturates have ready access to the brain because they can cross the blood brain barrier easily. ------------------------------------------------------------------------**Bibliography**. Different barbiturates clear out of the blood stream at different rates.
