Sodium thiopental, also known as Sodium Pentothal, thiopental, thiopentone, or Trapanal, is a rapid-onset short-acting barbiturate general anesthetic. It is the thiobarbiturate analog of pentobarbital, and an analog of thiobarbital. Sodium thiopental was a core medicine in the World Health Organization's List of Essential Medicines, but was supplanted by propofol. Despite this, thiopental is listed as an acceptable alternative to propofol, depending on local availability and cost of these agents. It was previously the first of three drugs administered during most lethal injections in the United States, but the US manufacturer Hospira stopped manufacturing the drug in 2011 and the European Union banned the export of the drug for this purpose. Although thiopental abuse carries a dependency risk, its recreational use is rare.
Carisoprodol, sold under the brand name Soma among others, is a medication used for musculoskeletal pain. Effects generally begin within half an hour and last for up to six hours. It is taken orally.
John Bodkin Adams was a British general practitioner, convicted fraudster, and suspected serial killer. Between 1946 and 1956, 163 of his patients died while in comas, which was deemed to be worthy of investigation. In addition, 132 out of 310 patients had left Adams money or items in their wills.
Phenobarbital, also known as phenobarbitone or phenobarb, sold under the brand name Luminal among others, is a medication of the barbiturate type. It is recommended by the World Health Organization (WHO) for the treatment of certain types of epilepsy in developing countries. In the developed world, it is commonly used to treat seizures in young children, while other medications are generally used in older children and adults. In developed countries it is used for veterinary purposes. It may be used intravenously, injected into a muscle, or taken by mouth. The injectable form may be used to treat status epilepticus. Phenobarbital is occasionally used to treat trouble sleeping, anxiety, and drug withdrawal and to help with surgery. It usually begins working within five minutes when used intravenously and half an hour when administered by mouth. Its effects last for between four hours and two days.
Meprobamate—marketed as Miltown by Wallace Laboratories and Equanil by Wyeth, among others—is a carbamate derivative used as an anxiolytic drug. It was the best-selling minor tranquilizer for a time, but has largely been replaced by the benzodiazepines due to their wider therapeutic index and lower incidence of serious side effects.
Butabarbital is a prescription barbiturate sleep aid and anxiety medication. Butabarbital has a particularly fast onset of effects and short duration of action compared to other barbiturates, which makes it useful for certain applications such as treating severe insomnia, relieving general anxiety and relieving anxiety before surgical procedures; however it is also relatively dangerous particularly when combined with alcohol, and so is now rarely used, although it is still prescribed in some Eastern European and South American countries. Its intermediate duration of action gives butabarbital an abuse potential slightly lower than secobarbital. Butabarbital can be hydrolyzed to valnoctamide.
Central nervous system (CNS) depression is a physiological state that can result in a decreased rate of breathing, decreased heart rate, and loss of consciousness, possibly leading to coma or death.
Clomethiazole is a sedative and hypnotic originally developed by Hoffmann-La Roche in the 1930s. The drug is used in treating and preventing symptoms of acute alcohol withdrawal.
Nikethamide is a stimulant which mainly affects the respiratory cycle. Widely known by its former trade name of Coramine, it was used in the mid-twentieth century as a medical countermeasure against tranquilizer overdoses, before the advent of endotracheal intubation and positive-pressure lung expansion. It is no longer commonly considered to be of value for such purposes.
An analeptic, in medicine, is a central nervous system stimulant. The term "analeptic" typically refers to respiratory stimulants. Analeptics are central nervous system (CNS) stimulants that include a wide variety of medications used to treat depression, attention deficit hyperactivity disorder (ADHD), and respiratory depression. Analeptics can also be used as convulsants, with low doses causing patients to experience heightened awareness, restlessness, and rapid breathing. The primary medical use of these drugs is as an anesthetic recovery tool or to treat emergency respiratory depression. Other drugs of this category are prethcamide, pentylenetetrazole, and nikethamide. Nikethamide is now withdrawn due to risk of convulsions. Analeptics have recently been used to better understand the treatment of a barbiturate overdose. Through the use of agents, researchers were able to treat obtundation and respiratory depression.
R v Adams [1957] is an English case that established the principle of double effect applicable to doctors: that if a doctor "gave treatment to a seriously ill patient with the aim of relieving pain or distress, as a result of which that person's life was inadvertently shortened, the doctor was not guilty of murder" where a restoration to health is no longer possible. Such medicines are among those sometimes used in palliative care, most commonly for the most severe pain.
Gertrude "Bobby" Hullett, a resident of Eastbourne, East Sussex, England, was a patient of Dr John Bodkin Adams, who was indicted for her murder but not brought to trial for it. Adams was tried in 1957 for the murder of Edith Alice Morrell, and the prosecution intended to proceed with the Hullett indictment as a second prosecution that could follow the Morrell case in certain circumstances, although it did not bring the case to trial following the verdict in the Morrell trial.
Edith Alice Morrell was a resident of Eastbourne, East Sussex, England, and patient of Dr John Bodkin Adams. Although Adams was acquitted in 1957 of her murder, the question of Adams' role in Morrell's death excited considerable interest at the time and continues to do so. This is partly because of negative pre-trial publicity which remains in the public record, partly because of the several dramatic incidents in the trial and partly as Adams declined to give evidence in his own defence. The trial featured in headlines around the world and was described at the time as "one of the greatest murder trials of all time" and "murder trial of the century". It was also described by the trial judge as unique because "the act of murder" had "to be proved by expert evidence." The trial also established the legal doctrine of double effect, where a doctor giving treatment with the aim of relieving pain may, as an unintentional result, shorten life.
Herbert Wheeler Walter Hannam was a British policeman within the Metropolitan Police Service. He was based at Scotland Yard where he held the rank of Detective Superintendent.
Arthur Henry Douthwaite was a British medical doctor, Vice President of the Royal College of Physicians and a prolific medical textbook writer. He was described as the foremost expert on heroin in Britain in the 1950s, or as a leading authority on opiates and he was called as an expert witness for the prosecution in the trial of Dr John Bodkin Adams for the murder of Mrs Edith Morrell.
A convulsant is a drug which induces convulsions and/or epileptic seizures, the opposite of an anticonvulsant. These drugs generally act as stimulants at low doses, but are not used for this purpose due to the risk of convulsions and consequent excitotoxicity. Most convulsants are antagonists at either the GABAA or glycine receptors, or ionotropic glutamate receptor agonists. Many other drugs may cause convulsions as a side effect at high doses but only drugs whose primary action is to cause convulsions are known as convulsants. Nerve agents such as sarin, which were developed as chemical weapons, produce convulsions as a major part of their toxidrome, but also produce a number of other effects in the body and are usually classified separately. Dieldrin which was developed as an insecticide blocks chloride influx into the neurons causing hyperexcitability of the CNS and convulsions. The Irwin observation test and other studies that record clinical signs are used to test the potential for a drug to induce convulsions. Camphor, and other terpenes given to children with colds can act as convulsants in children who have had febrile seizures.
Amiphenazole (Daptazile) is a respiratory stimulant traditionally used as an antidote for barbiturate or opiate overdose, usually in combination with bemegride, as well as poisoning from other sedative drugs and treatment of respiratory failure from other causes. It was considered particularly useful as it could counteract the sedation and respiratory depression produced by morphine but with less effect on analgesia. It is still rarely used in medicine in some countries, although it has largely been replaced by more effective respiratory stimulants such as doxapram and specific opioid antagonists such as naloxone.
Desbutal was a brand name drug by Abbott containing 5 mg methamphetamine hydrochloride (Desoxyn) and 30 mg pentobarbital sodium (Nembutal); a substituted amphetamine and a barbiturate combined within the same pill. Desbutal was marketed as an antidepressant as well as a medication for the treatment of obesity, narcolepsy, parkinsonism, and alcoholism, although it was commonly also prescribed off-label for miscellaneous ailments. It had a high abuse potential and is no longer manufactured.
Barbiturates are a class of depressant drugs that are chemically derived from barbituric acid. They are effective when used medically as anxiolytics, hypnotics, and anticonvulsants, but have physical and psychological addiction potential as well as overdose potential among other possible adverse effects. They have been used recreationally for their anti-anxiety and sedative effects, and are thus controlled in most countries due to the risks associated with such use.
Barbiturate overdose is poisoning due to excessive doses of barbiturates. Symptoms typically include difficulty thinking, poor coordination, decreased level of consciousness, and a decreased effort to breathe. Complications of overdose can include noncardiogenic pulmonary edema. If death occurs this is typically due to a lack of breathing.
