What are Barbiturates?
Denial of a barbiturate to the habitual user may precipitate a withdrawal syndrome that is indicative of physiological dependence on the drug. An overdose of barbiturates can result in coma and even death due to severe depression of the central nervous and respiratory systems. Ultra short acting barbiturates are injected intravenously and used in anesthesia. If you notice withdrawal symptoms when you stop taking barbiturate medications, you should talk to your healthcare provider.
- The prescription drug monitoring program serves to identify potential misuse and abuse.[76] Benzodiazepines have primarily replaced them when used for anti-anxiety or insomnia.
- In addition to having a narrow therapeutic index, barbiturates are also addictive.
- Barbiturates are medications that cause you to relax or feel drowsy.
- All local poison control centers in the United States use this national number.
- Barbiturates have some risks, but these risks should be minimal if you take your medication exactly as prescribed.
Thiopental is relatively short-acting and is used to induce anesthesia before general anesthetics are given. German researcher Adolph von Baeyer was the first to synthesize barbituric acid. Barbital (Veronal) was the first barbiturate and was used for medical purposes in 1903. Barbiturates were frequently used to treat agitation, anxiety, and insomnia, but their use for treating such symptoms fell out of favor due to the risk of overdose and abuse.
Some symptoms of an overdose typically include sluggishness, incoordination, difficulty in thinking, slowness of speech, faulty judgement, drowsiness, shallow breathing, staggering, and, in severe cases, coma or death. The lethal dosage of barbiturates varies greatly with tolerance and from one individual to another. The lethal dose is highly variable among different members of the class, with superpotent barbiturates such as pentobarbital being potentially fatal in considerably lower doses than the low-potency barbiturates such as butalbital. Even in inpatient settings, the development of tolerance is still a problem, as dangerous and unpleasant withdrawal symptoms can result when the drug is stopped after dependence has developed. Tolerance to the anxiolytic and sedative effects of barbiturates tends to develop faster than tolerance to their effects on smooth muscle, respiration, and heart rate, making them generally unsuitable for a long time psychiatric use. Tolerance to the anticonvulsant effects tends to correlate more with tolerance to physiological effects, however, meaning that they are still a viable option for long-term epilepsy treatment.
Most are rapidly metabolized to inactive compounds before they are excreted in the urine. However, phenobarbital is only partially converted and can be found unchanged in the urine. Phenobarbital is a long-acting, polar drug that is slowly absorbed and slowly redistributed, contributing to its longer duration of action. Barbiturates easily cross the placenta and are excreted into breast milk.
You should call if you have any questions about poisoning or poison prevention. Call your local emergency number, such as 911, if someone has taken barbiturates and seems genetics and alcoholism pmc extremely tired or has breathing problems. In select and extreme cases of overdose, dialysis (kidney machine) may be used to help remove the medicine from the blood.
This barbiturate was used to treat seizures in young children due to its effectiveness as an anticonvulsant. It has also been used to treat anxiety, drug withdrawal (particularly from other barbiturates), and sleep aid. In addition to having a narrow therapeutic index, barbiturates are also addictive. If taken daily for longer than about 1 month, the brain develops a need for the barbiturate, which causes severe symptoms if the drug is withheld. Although the medical use of barbiturates has declined since the 1970s, high school surveys suggest misuse has been rising over the last 10 years. A common reason to misuse barbiturates is to counteract the symptoms of other drugs; the barbiturates (“downers”) counteract the excitement and alertness obtained from stimulant drugs like cocaine and methamphetamines.

Barbiturates are medications used for treating headaches, insomnia, and seizures. Alcohol and barbiturates can interact and cause a much stronger effect. This can cause severe drowsiness, passing out or trouble breathing. In severe cases, this could cause a person to have severe organ damage, or it could be deadly. However, barbiturates are still proven medications for treating many conditions. They also combine well with other medications like acetaminophen (Tylenol® or Paracetamol®) to treat certain conditions.
Signs of a barbiturate overdose include clammy skin, dilated pupils, shallow respiration, rapid and weak pulse, and coma. The pharmacological actions of barbiturates include depressing nerve activity in the cardiac, smooth, and skeletal muscles. These drugs also affect the CNS in several ways and can produce effects ranging from mild sedation to a coma depending on the dosage. These drugs are sometimes prescribed to help reduce anxiety and induce sleep, but they can also be dangerous and habit-forming.
This can result in fatal overdoses from drugs such as codeine, tramadol, and carisoprodol, which become considerably more potent after being metabolized by CYP enzymes. Barbiturates in overdose with other CNS (central nervous system) depressants (e.g. alcohol, opiates, benzodiazepines) are even more dangerous owing to additive CNS and respiratory depressant effects. In the case of benzodiazepines, not only do they have additive effects, barbiturates also increase the binding affinity of the benzodiazepine binding site, leading to exaggerated benzodiazepine effects. Barbiturates became known as “goofballs” about the time of World War II, when they were used to help soldiers cope with combat conditions. Between the 1940s and ’70s, however, the abuse of barbiturate drugs became highly prevalent in Western societies.
Legal status
The prescription of barbiturates and subsequent monitoring necessitates an interprofessional team approach, fostering collaboration across various disciplines to achieve optimal patient outcomes in barbiturate therapy. Presently, barbiturates are nearly nonexistent on the black market. However, although illegal barbiturate use is rare, it remains an extremely dangerous drug to abuse because of the high risk of fatal overdose. The risk of a fatal overdose is higher with barbiturates than other drugs as the difference between a safe dose and a deadly one is small.

What Causes Insomnia?
Barbiturates are a class of drugs that were used extensively in the 1960s and 1970s as a treatment for anxiety, insomnia, and seizure disorders. Apart from a few specific indications, they are not commonly prescribed these days, hallucinogens effects, addiction potential and treatment options having been largely superseded by benzodiazepines, which are much safer, although still potentially addictive. Barbiturates also easily produce tolerance, meaning it takes more of the drug to produce the same effects.
If you believe someone has taken barbiturates inappropriately, take them to a hospital emergency department for evaluation by a doctor. Soon after taking barbiturates, a person may only be drowsy or seem intoxicated, but more serious symptoms can develop quickly and unpredictably. Symptoms of withdrawal or abstinence include tremors, difficulty sleeping, and agitation. Because these medications can last up to twelve hours, they can also be used to treat the withdrawal symptoms of barbiturate addiction during a medically supervised detox program. These types of barbiturates are used for mental health treatment and other healthcare purposes, including anxiety, insomnia, and seizures.
However, barbiturates are highly addictive, and abusing them can have dire consequence. Barbiturates slow down the CNS in a similar way to alcohol and, depending on how rapidly they produce effects and the duration of those effects, they may be classed as ultra-short-, short-, intermediate-, or long-acting. Barbiturates used to be regularly prescribed to treat insomnia, depression, and anxiety. Notably, the small difference between a normal dose and an overdose led to a number of accidental deaths, as well as people using them to commit suicide. It is important to always tell your doctor, pharmacist, or health care provider of all prescription and over-the-counter medications you use, as well as the dosage for each, and keep a list of the information. Check with your doctor or health care provider if you have any questions about the medication.
Other options for managing barbiturate toxicity include forced alkaline diuresis and hemodialysis for severe cases. Bemegride (Megimide) is a central nervous system stimulant that increases respiration and can be used as a treatment for depressant toxicity. It is, however, an emetic that raises the concern of emesis and aspiration. Pharmacological barbiturates are based on the parent compound barbituric acid. The type of barbiturate depends on the substituent used at position 5 of this basic skeleton.
They may also be combined with other medications to treat migraines. Barbiturates are typically broken into four classifications according to how quickly and strongly they affect the brain and body. Sally first developed an interest in medical communications when she took on the role of Journal Development Editor for BioMed Central (BMC), after having graduated with a degree in biomedical science from Greenwich University. People who frequently use barbiturates may reach a constant state that is similar to a drunken daze.
