Prescription CNS depressants act on the brain by increasing activity of GABA, a chemical that slows brain activity. People who start taking prescription CNS depressants usually feel sleepy and uncoordinated at first. They can also have poor concentration, confusion, lowered blood pressure, and slowed breathing.
What causes CNS depression?
Central nervous system — or CNS — depression happens when the body’s normal neurological functions slow down. It can result from substance overdoses, poisoning, or other medical conditions. Depression of the central nervous system or CNS often occurs when a person misuses a substance that slows brain activity.
What do depressants do?
What They Do: When used as prescribed by a doctor, depressants can calm nerves and relax muscles. Larger or improperly used doses of depressant drugs can cause confusion, lack of coordination, low blood pressure, and slowed heart rate and breathing.
Do depressants depress the CNS?
Effects of Central Nervous System Depressants. Central nervous system depressants work by increasing the production of the neurotransmitter GABA, which in turn slows down brain activity and produces feelings of relaxation, drowsiness, and a number of other effects, including: Lowered blood pressure. Dilated pupils.Is CNS depression serious?

What is CNS in medical terms?
Definition of central nervous system : the part of the nervous system which in vertebrates consists of the brain and spinal cord, to which sensory impulses are transmitted and from which motor impulses pass out, and which coordinates the activity of the entire nervous system — compare peripheral nervous system.
How do barbiturates affect your behavior?
Barbiturates have several effects on behavior depending on the dose: In low doses: barbiturates reduce anxiety; reduce respiration, reduce blood pressure, reduce heart rate and reduce rapid eye movement (REM)sleep. In higher doses: barbiturates can actually increase some types of behavior and act like a stimulant.
What are the short term effects of barbiturates?
Barbiturates may cause drowsiness, dizziness, lightheadedness, or decreased alertness. These side effects may be present the morning after taking a barbiturate at bedtime.
Do barbiturates increase GABA?
Barbiturates enhance GABA-mediated chloride currents by binding to the GABA-A receptor–ionophore complex and increasing the duration of ionophore opening. At high doses, barbiturates stimulate GABA-A receptors directly in the absence of GABA.
What are examples of barbiturates drugs?
- Seconal (secobarbital)
- Seconal Sodium (secobarbital)
- Butisol Sodium (butabarbital)
- Medaral (mephobarbital)
- Nembutal Sodium (pentobarbital)
- Luminal (phenobarbital)
- Amytal Sodium (amobarbital)
- Nembutal (pentobarbital)

Is coffee a CNS stimulant?
Caffeine is the most widely consumed central-nervous-system stimulant. Three main mechanisms of action of caffeine on the central nervous system have been described. Mobilization of intracellular calcium and inhibition of specific phosphodiesterases only occur at high non-physiological concentrations of caffeine.
Is nicotine a CNS stimulant or depressant?
Nicotine acts as both a stimulant and a depressant to the central nervous system. Nicotine first causes a release of the hormone epinephrine, which further stimulates the nervous system and is responsible for part of the “kick” from nicotine-the drug-induced feelings of pleasure and, over time, addiction.
