Naltrexone and acamprosate can both reduce heavy drinking and support abstinence. In the brain, alcohol increases the neurotransmitter gamma-aminobutyric acid (GABA), which results in lower levels of anxiety, stress, and fear. Neurotransmitters are the chemicals that control communication between nerve cells. In addition, drinking alcohol quickly and in large amounts can lead to more severe symptoms, such as memory loss, coma, even death. Misuse can also happen if a person uses someone else’s medication, if they take more than the recommended dose, or if they use drugs that a doctor has not prescribed.

Alcohol is a depressant that slows down your central nervous system, leading to decreased blood pressure, drowsiness, poor coordination, and reduced alertness.

These medications are prescribed in the form of a pill, capsule, or liquid that you take orally. They work by increasing your brain’s production of a chemical called gamma-aminobutyric acid (GABA). The more you drink, the more tolerance you build up and it becomes harder to tap into the happy chemicals. Plus, the more your brain relies on alcohol to produce dopamine and serotonin, the less it relies on the body to pick up the slack. As a result, these neurotransmitters will remain low without the presence of alcohol. Consuming too much alcohol too quickly can affect breathing, body temperature, and heart rate.

  1. Depression of the central nervous system or CNS often occurs when a person misuses a substance that slows brain activity.
  2. However, initially and in small doses, alcohol is a stimulant.
  3. When you start drinking, booze acts like a stimulant, making you excited and energetic.
  4. Benzodiazepines, for example, can alter mood and trigger depression, especially if you take them for an extended period of time.
  5. People take them as a sleep aid, and use them to ease muscle spasms and prevent seizures.

Linde, a psychiatric consultant with Ria Health, an online addiction treatment program.

A review on alcohol: from the central action mechanism to chemical dependency

Neurons use both electrical and chemical signals to communicate information – chemical signals are needed because electrical signals alone can’t transfer from one neuron to another. The chemical signals, known as neurotransmitters, help bind neuron receptors. The depressant effect of alcohol can get worse if you drink to excess. Potentially fatal liver problems and spikes in blood pressure are other really good reasons not to mix these drugs.

It can also cause other side effects, including a risk for dependence and addiction. A person drinking alcohol may experience impaired judgment or slower reaction times. These drugs are often used to treat anxiety, minimize pain, relieve muscle spasms, sleep disorders, and address other mental health issues. Examples of CNS depressants include tranquilizers, hypnotics, and sedatives.

In extreme cases, alcohol poisoning can cause brain damage or even death. Under the guidance of a medical professional, stimulants may be helpful for certain individuals. However, misuse of stimulants can have serious health consequences, including physical dependence and stimulant addiction, also known as stimulant use disorder. A large 2018 study indicated that any level of drinking is harmful. Over 140,000 people in the U.S. die from overconsuming alcohol each year.

Why does it feel good to be drunk?

Since alcohol is widely abused and alcohol dependence often leads to serious medical and social problems, medication is very important. It is crucial that we understand the complex mechanism of action of alcohol to find better therapeutic alternatives. Alcohol acts on various neurotransmitters such as gamma-aminobutyric acid (GABA), glutamate, dopamine, serotonin, and endogenous opioids. Alcohol is both a GABA agonist and a glutamate N-methyl-d-aspartate (NMDA) receptor antagonist.

However, drinking too much can cause negative side effects, such as nausea and vomiting. Long-term overuse of alcohol can cause physical and psychological dependence. People who are dependent on alcohol may experience withdrawal symptoms when they try to quit drinking. These symptoms may range from nausea and anxiety to seizures and hallucinations. If you’re undergoing alcohol withdrawal symptoms or want to reduce alcohol cravings, you may be prescribed medication.

A person who wishes to stop using a CNS depressant may need to stop gradually to prevent adverse effects. In 2020, the Food and Drug Administration (FDA) strengthened their warning that benzodiazepine use can lead to addiction. Combined with alcohol, opiods, and other CNS depressants, they can be life-threatening.

Dependence and withdrawal

The type of alcohol in alcoholic beverages is ethanol, or ethyl alcohol. Manufacturers create alcoholic drinks through a process called fermentation. During this process, yeast converts carbohydrates into alcohol. Some are safer than others, but all produce lower levels of awareness in the brain and cause the activity in the CNS to slow down.

These medications are designed to slow your brain down, relax your muscles, and provide a sense of calm. Alcohol is known as a psychotropic depressant because it slows down your central nervous system. When you drink alcohol, a complex process occurs in your brain that inhibits neurons by impacting their ability to transmit impulses. 5 key differences between crack and cocaine At the same time, alcohol also increases the production of neurotransmitters that make you feel good. Even if you’re drinking the same alcoholic beverage at the same rate as someone else, your reactions will differ. It’s important to remember that alcohol is a depressant, and you can overdose if you drink too much.
