List of CNS stimulants + Uses & Side Effects
For the last chapter in this unit, we will take a detailed look at alcohol, the most infamous depressant of all. Much of the terminology used to describe alcohol’s effects will have already been introduced in this chapter, so make sure you are comfortable with this chapter’s material before moving on. A common mode of nitrous oxide recreational use is inhalation or collection of the gas from cooking sprays and whipped cream canisters that use nitrous oxide as the propellant.
Because inhalants are a heterogeneous collection of chemicals, it can be cns depression drugs difficult to summarize drug actions. Inhalants often are allosteric modulators of GABAA receptors as well as antagonists at glutamate NMDA receptors. Both actions result in decreased CNS activity and depressant effect.

Only a doctor should prescribe a CNS depressant, and people should only use these drugs for the specified purpose, according to the doctor’s instructions. People who take CNS depressants must be aware of the risks and should never share drugs or take a substance without knowing what is in it. CNS depression or overdose is a common cause of poisoning in many developed countries, including the U.S. and Canada. Anyone witnessing signs of CNS depression or an overdose in another person should call the emergency services or local poison control center for guidance.
In a recent study supported by the National Institute of Mental Health, researchers examined the impact of a family-based intervention on suicide risk in youth and found risk-reduction benefits up to 10 years later. NIMH supported science and NIMH researchers helped pave the way for the development of ketamine—a groundbreaking treatment that has improved the lives of those who are impacted by treatment-resistant depression. Explore key milestones, discoveries, and the impact of NIMH-funded studies on mental health. The Division of Intramural Research Programs (IRP) is the internal research division of the NIMH.
In a life-threatening situation, a drug called naloxone can reverse the toxic effects of an opioid overdose. Certain drugs affect the neurotransmitters in your brain, causing brain activity to slow. The central nervous system is made up of the brain and spinal cord, which control most bodily functions, including breathing and the heart. CNS depression occurs when a person’s central nervous system has slowed down, causing a slower heart rate and slower breathing. Depression of the central nervous system (CNS) typically occurs when a person uses a substance that is designed to slow down your brain and relax your muscles, leaving you with a feeling of calm.
What are the differences between CNS stimulants?
- Common barbiturates include Amytal, Luminal (phenobarbital), Mebaral, Nembutal, and Seconal.
- More studies are needed to explore the underlying mechanisms, optimal timing for intervention, and the types of patients who would benefit the most from these specific medications.
- ME contributed to interpretation of data and revise the manuscript.
- People using central nervous system depressants might sometimes experience mild depression as a side effect.
- GHB is both an endogenous neurochemical as well as an exogenous chemical compound.
Although they have a lower risk of dependency than other CNS depressants, long-term use may cause the condition. More importantly, tests of cognitive decline administered during the study showed patients on commonly used antidepressants actually declined more slowly than what is typical for dementia patients overall, Isaacson said. The client should be advised to take the prescribed medication as directed. Clients who undergo prolonged therapy should not discontinue treatment abruptly as this may cause the onset of seizure activity. Female clients using oral contraceptives should also use non-hormonal-based contraceptives during therapy involving barbiturate use. Benzodiazepines may cause fetal harm when administered to pregnant women.

Treatment for barbiturate dependence involves detoxification and gradual reduction in symptoms of dependence. Fortunately, the withdrawal symptoms can be suppressed by safer sedative-hypnotic drugs like benzodiazepines. Barbiturates are typically prescribed to reduce anxiety and treat sleep disorders. However, because of their high risk of overdose, doctors use them less frequently for those conditions and more frequently to treat seizure disorders or in surgical procedures. Mild CNS depression is often the goal of taking some CNS depressants, especially sleep and anxiety disorders.
- An increase in the activity of GABA in your brain leads to a slowdown of your brain activity.
- Ultimately in severe cases, CNS depression causes unconsciousness and coma.
- It can either be administered as an injection or given intravenously.

- There can be physical symptoms too, like nausea, dizziness, restlessness and palpitations.
Avoidable deaths increased in the U.S. as they dropped elsewhere
Ultrashort-acting barbiturates such as thiopental have the highest lipid solubility out of all barbiturates. Time to action can be mere minutes, although effects only last for around half an hour. Drugs like these are more suited for serving as general anesthetics for short surgical procedures.
Treatment for SUD is available through counseling and supportive medications. The most important thing is to be honest with your prescriber regarding your symptoms, and to communicate honestly. Discuss treatment goals and alternatives to the use of opiates so that opiate use is limited. Overdoses of prescription painkillers in the U.S. is a growing problem, especially among women, according to the Centers for Disease Control and Prevention (CDC). These are chemically different from other CNS depressants, but they work by stimulating the same inhibitory neurotransmitter, GABA. Both opiates and opioids work by interfering with the CNS and blocking pain signals to the brain.
At physiological concentrations, GHB the neurotransmitter has affinity and efficacy for specific GHB receptors that are excitatory GPC receptors that evoke a stimulatory response. These receptors enhance glutamate activity and stimulate dopamine and serotonin release. The release of dopamine due to GHB receptor activity also contributes to the addictive properties of the drug. When GHB and alcohol are combined, the sedative and depressant effects are amplified, and GHB may reduce the rate at which alcohol is eliminated from the system.
Now, the Trump administration has announced that these drugs, which have been in use for decades and gone through rigorous testing, will be subject to new scrutiny. Learn about NIMH priority areas for research and funding that have the potential to improve mental health care over the short, medium, and long term. Since depression itself has been linked with dementia and cognitive impairment 41, 42, we did a sensitivity analysis among patients without depression to reduce the indication bias. Furthermore, to avoid floor effects, we did a sensitivity analysis among patients with MMSE ≥ 10 and without depression, excluding patients with baseline severe dementia.
That’s because you may be prone to taking more medication than prescribed or combining medication with other drugs or alcohol. In small doses, these drugs slow brain function, producing a calm or sleepy feeling. The danger is when the CNS is slowed too much, which can lead to unconsciousness, coma, and death.
For the last section of our chapter on depressants, we will cover a type of drug that many people might overlook. Inhalants are solvents or other materials that produce vapors that elicit psychoactive effects. While a wide variety of products can be used as inhalants, most induce CNS depression through similar mechanisms of action.
This synergistic interaction can lead to unexpected respiratory failure and death. GHB is metabolized rapidly and has a short half-life of about 30 minutes. Because of this, GHB is eliminated from the body faster than most drugs and can only be detected for 8-12 hours after its administration. This is part of the reason why the use of GHB as a date-rape drug is hard to track.
Many CNS depressants work by increasing the activity of the neurotransmitter gamma-aminobutyric acid (GABA), a chemical that prevents or slows the delivery of messages between cells. Combining different CNS depressants, such as painkillers and alcohol, can be life-threatening.
