By increasing GABA activity, brain activity is reduced, leading to a relaxing effect. Several substances can depress the CNS, ranging from anti-anxiety and sleep medications to so-called recreational drugs, such as heroin. Depression of the central nervous system or CNS often occurs when a person misuses a substance that slows brain activity. Often the abuse of barbiturates and benzodiazepines occurs in conjunction with the abuse of another substance or drug, such as alcohol or cocaine.
- Discuss treatment goals and alternatives to the use of opiates so that opiate use is limited.
- CNS depressants have a compound called gamma-hydroxybutyrate, which is also naturally present in the body and gets converted into gamma aminobutyric acid (GABA).
- Hydrocodone (an opioid) was the most commonly endorsed CNS-D prescription (24% of CNS-D prescription medication mentions) and was used by 3.2% of the population.
- Participants who reported having taken any prescription medications in the past 30 days were asked to show their medication containers to the interviewer, who entered the product name in the computer.
Drugs that cause CNS depression
Misusing sedatives and prolonging their use may lead to dependency and eventual withdrawal symptoms. 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. At high doses, barbiturates can result in generalized CNS depression. Symptoms include loss of muscle coordination, difficulty thinking and speaking, and shallow breathing. These symptoms often result in behavior similar to that exhibited by someone who is drunk.
What causes CNS depression?
These symptoms can be minimized or avoided by slowly reducing the dose of the medication over a period of time to gradually wean off the substance. Barbiturates, sometimes referred to as downers, are a type of CNS depressant that causes euphoria and relaxation when taken in small doses. Drugs that fall into this category include Mebaral (mephobarbital), Luminal (phenobarbital), and Nembutal (pentobarbital sodium). 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. A person may need emergency care if they are unaware that they are experiencing a CNS depressant overdose, especially after accidentally misusing their medication or due to a medical problem. Treatment for CNS depression or CNS depressant overdose depends on the substances involved.

These drugs are designed to specifically treat insomnia and other sleep disorders. These sleeping pills are chemically different from other central nervous system depressants, and they work by stimulating the GABA neurotransmitter in a different way. The drugs are thought to have fewer side effects and risk of addiction compared to benzodiazepines; however, long-term use can still result in dependence and addiction. The degree to which the brain is affected by this central nervous system depressant depends on how much, and how fast, a person drinks.
Thus, analyses utilized data from participants who participated in both the in-home interview and MEC portions of the NHANES. Analyses were also limited to ages 20 and over because alcohol data were not available for individuals under the age of 20 for all years. Additional details about NHANES procedures are available elsewhere (Grucza et al., 2018). However, these drugs are prone to misuse and may cause severe side effects. Because their body has become used to the sedative’s effects, a person may also develop a tolerance to the drug or get a reduced effect from it. As a result, they may need higher doses to achieve the same initial effect.
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. GHB found its main use as a club drug or party drug because of its euphoric effects at low doses. alcohol withdrawal symptoms, treatment and timeline It is also easier to manufacture than most other club drugs, making it an attractive alternative. GHB is also occasionally used as a date-rape drug due to the drug’s ability to induce unconsciousness and amnesia. It is colorless and odorless and can be easily poured into a drink without notice.
People with any of these conditions should check with a doctor before using a CNS depressant. If severe CNS depression is left untreated, it can be fatal for the person living with the condition. When you first begin taking a CNS depressant, you may feel unusually sleepy or uncoordinated as your body adjusts to the medication. Receive free access to exclusive content, a personalized homepage based on your interests, and a weekly newsletter with the topics of your choice. CNS (central nervous system) stimulants are medicines that stimulate the brain, speeding up both mental and physical processes. Dispen3D is setting new standards in single-cell biology, enabling researchers to conduct high-precision experiments that drive advancements in drug discovery, personalized medicine, and regenerative therapies.
Barbiturate use has also declined due to the risk of certain side effects. Negative effects of barbiturates include impaired memory, judgment, and coordination, along with increased feelings of irritability, paranoia, and suicidal ideation. Misuse can also happen if a person uses someone else’s medication, if they take more than the recommended compare different sober houses dose, or if they use drugs that a doctor has not prescribed. CNS depressants are medications and other substances that slow down the CNS. A person may benefit from taking the correct dose of a CNS depressant, such as an opioid pain relief medication. If it is a result of the misuse of CNS depressants, certain medications are prescribed.
CNS depressants are often prescribed to treat conditions related to stress, anxiety, sleep disorders, and seizures. These medications can be safe and effective, but they do have a risk for tolerance, dependence, and overdose. CNS depressants work by increasing the activity of a neurotransmitter in your brain, called gamma-aminobutyric acid (GABA).
Many kinds of antidepressants are available, and chances are you’ll be able to find one that works well for you. Find out everything you need to know about weight loss drugs in our prescription weight loss drug guide. For a more extensive list of side effects, click on the individual drugs.
If you have a medical condition that puts you at risk for CNS depression, talk to your doctor. Discuss the best way to manage your health and how to recognize possible complications of your disease early on. Most inhalants are lipid-soluble and are absorbed very quickly, with concentrations in the blood peaking close to the time of administration.
As indicated by the name, inhalants are administered by inhaling the substance over some time at high concentrations. GHB is an endogenous neurotransmitter that is synthesized in GABA neurons. There appears to be a dynamic relationship between GHB and GABA in that each is a precursor as well as a by-product of the other. There are two orthostatic or primary binding sites on the chloride channel which interact with molecules of GABA.
Recall from Chapter 4 that γ-aminobutyric acid (GABA) is the brain’s main inhibitory neurotransmitter. This is because GABA targets GABA receptors, which promote hyperpolarization of the postsynaptic cell. This inhibits famous alcoholics you never knew about the postsynaptic cell from firing and releasing other neurotransmitters such as glutamate or norepinephrine. As a result, increasing GABA activity will, in general, reduce the activity of other neurons and transmitters.
