Positive allosteric modulators do not increase the amount of GABA present in the synapse like reuptake inhibitors or activate the receptor on their own, as in the case of direct agonists. Instead, they change the conformation of the receptor so that it is more responsive to GABA binding. There are allosteric binding sites for various ligands, including benzodiazepines, barbiturates, and neurosteroids. As yet, an allosteric site where ethanol works is not known, although the inhibitory effects of ethanol are ultimately mediated through the GABAA receptor. Several substances can depress the CNS, ranging from anti-anxiety and sleep medications to so-called recreational drugs, such as heroin. Mild CNS depression due to prescription medication is to be expected and isn’t necessarily a problem if sedation is desired.

This makes them useful as anticonvulsants since fewer doses are required to maintain the level of drug in the body. Barbiturates are derived from barbituric acid, first synthesized in 1864 by the Bayer Company. No use was found for it until 1903 when German chemists discovered the sedative-hypnotic effects of its derived compounds. The first barbiturate, barbital, was marketed by Bayer under the name Veronal® that year, and barbiturate use steadily increased in the first half of the 20th century. Anyone witnessing signs of CNS depression or an overdose in another person should call the emergency services or local poison control center for guidance.
Is Addiction in Your Genes? Exploring Hereditary Addiction Factors
This turns into Stage 2, early CNS depression, which is characterized by slurred speech and hallucinations. In Stage 3, medium CNS depression, the user experiences confusion, delirium, and impaired muscle coordination (ataxia). Finally, Stage 4 is late CNS depression, which can cause stupor, seizure, coma, and death.
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. This synergistic interaction can lead to unexpected respiratory failure and death. The next depressant we will examine is gamma-hydroxybutyric acid (GHB). It is an endogenous substance that can also be taken as a medication or used recreationally. Although it primarily acts as a depressant, it causes biphasic effects, with stimulatory effects occurring at low doses or for a short time initially.
Pharmacology of Alcohol and Alcohol Use Disorder
We performed chi-square tests and independent sample t-tests to assess gender differences in initial reports of underlying disease, smoking status, exercise frequency, depressive symptoms, and anxiety symptoms. We used the Wilcoxon two-sample test to assess gender differences in AUDIT-KR scores. To investigate the relationship between global or component scores of the PSQI-K and AUDIT-KR scores, we performed the Mann-Whitney test. Now let’s take a closer look at the medication grid for phenobarbital in Table 8.5a.3 Medication grids are intended to assist students to learn key points about each medication class. Basic information related to a common generic medication in this class is outlined, including administration considerations, therapeutic effects, and side effects/adverse effects.
Much like barbiturates (sedatives), alcohol is a drug that affects the central nervous system (CNS) and the brain’s functionality. However, alleviating depression does not resolve the alcohol use disorder. In some cases, you may receive a dual diagnosis of a major depressive disorder (MDD) and an alcohol use disorder (AUD). This co-occurring disorder isn’t uncommon, but it can be difficult to treat. If you suffer from insomnia, anxiety, panic attacks, or seizures, your doctor may prescribe a class of drugs called central nervous system (CNS) depressants.
Barbiturates were routinely used to induce sleep in psychotic patients and were prescribed to treat insomnia and anxiety. They were also shown to reduce the number and intensity of seizures—a first since no other drugs were effective at treating epilepsy at the time—and began to see popular use as anticonvulsants. In 1912, Bayer produced another barbiturate, phenobarbital, which is still used to treat epilepsy to this day. Depression of the central nervous system or CNS often occurs when a person misuses a substance that slows brain activity. Having a history of addiction may put you at higher risk of CNS depression.
- Men with higher AUDIT-KR scores tended to suffer from poor sleep quality.
- Mixing CNS depressants, opioids, and alcohol increases their effect.
- Following a Mediterranean diet rich in omega-3s, for example, might be one recommendation.
- Whether you’re experiencing depression or not, it’s essential to evaluate your drinking habits and consider why you drink, when you drink, and how you feel when you drink.
This is why these medications specifically prohibit you from drinking alcohol while taking them. Benzodiazepines, also known as Benzos, are also used to treat anxiety and sleep disorders, although they are considered less addictive than barbiturates. Xanax, Valium, and Prosom are some of the most common types of Benzodiazepines. You might experience mild CNS depression from the prescribed use of CNS depressants or severe CNS depression from the misuse of CNS depressants, traumatic brain injury, or certain other conditions.
It can also feel rewarding to drink, as alcohol releases dopamine in the brain, encouraging you to keep drinking. The immediate effects of drinking alcohol can help you feel more What is Powdered Alcohol and is it Dangerous relaxed, more confident, and less inhibited. However, as these short-term effects wear off, other effects begin to take hold.
