Karl Abraham (03 May 1877 to 25 December 1925) was an influential German psychoanalyst, and a collaborator of Sigmund Freud, who called him his ‘best pupil’.
Peter Lorimer Benson (1946–2011) was a psychologist and CEO/President of Search Institute.
He pioneered the developmental assets framework, which became the predominant approach to research on positive facets of youth development.
Lazar lazar (Serbian Cyrillic: Лазаp Лаза Лазаревић, 13 May 1851 to 10 January 1891) was a Serbian Porn writer, psychiatrist, and neurologist.
After graduating, the post of “specialist doctor” at the General State Hospital in Belgrade awaited him. From then on until his premature death, Lazarević worked on reforming Serbian medicine as a primarius. He was a member of several Serbian Learned Societies, including SANU; and participated as a field doctor in the Serbo-Turkish War of 1876 and 1878. Also, he was a major organizer of the Great Reserve Hospital in Niš during the Serbo-Bulgarian War of 1885; vice-colonel, writer and translator and medicine scientist (published 72 works in local and foreign magazines). He founded the first modern geriatric hospital in Belgrade in 1881. His works were translated in numerous languages. Later he became doctor appointed to the Royal Court by King Milan Obrenović IV himself.
He is included in The 100 most prominent Serbs and he was elected a member of Parnassos Literary Society.
Kenneth Bancroft Clark (14 July 1914 to 01 May 2005) and Mamie Phipps Clark (18 April 1917 to 11 August 1983) were American psychologists who as a married team conducted research among children and were active in the Civil Rights Movement.
They founded the Northside Centre for Child Development in Harlem and the organization Harlem Youth Opportunities Unlimited (HARYOU). Kenneth Clark was also an educator and professor at City College of New York, and first Black president of the American Psychological Association.
They were known for their 1940s experiments using dolls to study children’s attitudes about race. The Clarks testified as expert witnesses in Briggs v. Elliott (1952), one of five cases combined into Brown v. Board of Education (1954). The Clarks’ work contributed to the ruling of the US Supreme Court in which it determined that de jure racial segregation in public education was unconstitutional. Chief Justice Earl Warren wrote in the Brown v. Board of Education opinion, “To separate them from others of similar age and qualifications solely because of their race generates a feeling of inferiority as to their status in the community that may affect their hearts and minds in a way unlikely to ever be undone.”
Paul Eugen Bleuler (30 April 1857 to 15 July 1939) was a Swiss psychiatrist and humanist most notable for his contributions to the understanding of mental illness.
He coined several psychiatric terms including “schizophrenia”, “schizoid”, “autism”, depth psychology and what Sigmund Freud called “Bleuler’s happily chosen term ambivalence”.
Władysław Witwicki (30 April 1878 to 21 December 1948) was a Polish psychologist, philosopher, translator, historian (of philosophy and art) and artist. He is seen as one of the fathers of psychology in Poland.
Witwicki was also the creator of the theory of cratism, theory of feelings, and he dealt with the issues of the psychology of religion, and the creation of secular ethics. He was one of the initiators and co-founders of Polish Philosophical Society. He is one of the thinkers associated with the Lwów-Warsaw school.
Pierre-Félix Guattari (30 March 1930 to 29 August 1992) was a French psychoanalyst, political philosopher, semiotician, social activist, and screenwriter.
He co-founded schizoanalysis with Gilles Deleuze, and ecosophy with Arne Næss, and is best known for his literary and philosophical collaborations with Deleuze, most notably Anti-Oedipus (1972) and A Thousand Plateaus (1980), the two volumes of their theoretical work Capitalism and Schizophrenia.
The Positive and Negative Syndrome Scale (PANSS) is a medical scale used for measuring symptom severity of patients with schizophrenia.
It was published in 1987 by Stanley Kay, Lewis Opler, and Abraham Fiszbein. It is widely used in the study of antipsychotic therapy. The scale is known as the “gold standard” that all assessments of psychotic behavioural disorders should follow.
The name refers to the two types of symptoms in schizophrenia, as defined by the American Psychiatric Association:
Some of these functions which may be lost include normal thoughts, actions, ability to tell fantasies from reality, and the ability to properly express emotions.
The PANSS is a relatively brief interview, requiring 45 to 50 minutes to administer. The interviewer must be trained to a standardised level of reliability.
To assess a patient using PANSS, an approximately 45-minute clinical interview is conducted. The patient is rated from 1 to 7 on 30 different symptoms based on the interview as well as reports of family members or primary care hospital workers.
PANSS Total score minimum = 30, maximum = 210
As 1 rather than 0 is given as the lowest score for each item, a patient can not score lower than 30 for the total PANSS score. Scores are often given separately for the positive items, negative items, and general psychopathology. In their original publication on the PANSS scale, Stanley Kay and colleagues tested the scale on 101 adult patients (20-68 years-old) with schizophrenia and the mean scores were,
Based on meta-analytic results, an alternative five-factor solution of the PANSS was proposed with positive symptoms, negative symptoms, disorganisation, excitement, and emotional distress.

A Subjective Units of Distress Scale (SUDS), also known as the Subjective Units of Disturbance Scale), is a scale ranging from 0 to 10 measuring the subjective intensity of disturbance or distress currently experienced by an individual.
Respondents provide a self report of where they are on the scale. The SUDS may be used as a benchmark for a professional or observer to evaluate the progress of treatment. In desensitisation-based therapies, and the patients’ regular self assessments enable them to guide the clinician repeatedly as part of the therapeutic dialogue.
The SUD-level was developed by Joseph Wolpe in 1969. It has been used in cognitive-behavioural treatments for anxiety disorders (e.g. exposure practices and hierarchy) and for research purposes.
There is no hard and fast rule by which a patient can self assign a SUDS rating to his or her disturbance or distress, hence the name subjective.
Some guidelines are:
There a number of version of the scale, and the below is for illustration only:
In using SUDS in a therapeutic setting, the therapist does not necessarily define the scale, because one of the benefits of asking a patient or client for a SUDS score is that it is simple. Typically, you can ask the client, “On a scale of zero to ten, where zero is the best you can feel and ten is the worst, how do you feel right now?”
The purpose of this question is to enable the patient or client to notice improvements, and the inherent difference between one person’s subjective scale and another person’s is irrelevant to therapy with either individual. Our brains are sophisticated enough that they can usually summarize a large amount of data very quickly, and often accurately.
There is a possibility that in some forms of therapy, the patient will want to see progress and will therefore report progress that isn’t objectively present – a type one error from a statistical point of view. While both type I and type II errors are important in research situations, type one errors can have a therapeutic utility in clinical situations, in which they can provide an indirect opportunity for positive autosuggestion – much like the indirect suggestions employed in Eriksonian hypnosis.
Thus, since the main use of SUDS is for clinical purposes, rather than research purposes, the imprecise nature of the scale is relatively unimportant to its main users: patients and clinicians.

Climazolam was introduced under licence as a veterinary medicine by the Swiss Pharmaceutical company Gräub under the tradename Climasol.
Climazolam is a benzodiazepine, specifically an imidazobenzodiazepine derivative developed by Hoffman-LaRoche.
It is similar in structure to midazolam and diclazepam and is used in veterinary medicine for anaesthetising animals.
Midazolam, sold under the brand name Versed, among others, is a benzodiazepine medication used for anaesthesia, procedural sedation, trouble sleeping, and severe agitation.
It works by inducing sleepiness, decreasing anxiety, and causing a loss of ability to create new memories. It is important to note that this drug does not cause an individual to become unconscious, merely be sedated. It is also useful for the treatment of seizures. Midazolam can be given by mouth, intravenously, by injection into a muscle, by spraying into the nose, or through the cheek. When given intravenously, it typically begins working within five minutes; when injected into a muscle, it can take fifteen minutes to begin working. Effects last between one and six hours.
Side effects can include a decrease in efforts to breathe, low blood pressure, and sleepiness. Tolerance to its effects and withdrawal syndrome may occur following long-term use. Paradoxical effects, such as increased activity, can occur especially in children and older people. There is evidence of risk when used during pregnancy but no evidence of harm with a single dose during breastfeeding. It belongs to the benzodiazepine class of drugs and works by increasing the activity of the GABA neurotransmitter in the brain.
Midazolam was patented in 1974 and came into medical use in 1982. It is on the World Health Organisation’s List of Essential Medicines. Midazolam is available as a generic medication. In many countries, it is a controlled substance.
Midazolam is among about 35 benzodiazepines currently used medically, and was synthesized in 1975 by Walser and Fryer at Hoffmann-LaRoche, Inc in the United States. Owing to its water solubility, it was found to be less likely to cause thrombophlebitis than similar drugs. The anticonvulsant properties of midazolam were studied in the late 1970s, but not until the 1990s did it emerge as an effective treatment for convulsive status epilepticus. As of 2010, it is the most commonly used benzodiazepine in anaesthetic medicine. In acute medicine, midazolam has become more popular than other benzodiazepines, such as lorazepam and diazepam, because it is shorter lasting, is more potent, and causes less pain at the injection site. Midazolam is also becoming increasingly popular in veterinary medicine due to its water solubility. In 2018 it was revealed the CIA considered using Midazolam as a “truth serum” on terrorist suspects in project “Medication”.
Midazolam is sometimes used for the acute management of seizures. Long-term use for the management of epilepsy is not recommended due to the significant risk of tolerance (which renders midazolam and other benzodiazepines ineffective) and the significant side effect of sedation. A benefit of midazolam is that in children it can be given in the cheek or in the nose for acute seizures, including status epilepticus. Midazolam is effective for status epilepticus that has not improved following other treatments or when intravenous access cannot be obtained, and has advantages of being water-soluble, having a rapid onset of action and not causing metabolic acidosis from the propylene glycol vehicle (which is not required due to its solubility in water), which occurs with other benzodiazepines.
Drawbacks include a high degree of breakthrough seizures – due to the short half-life of midazolam – in over 50% of people treated, as well as treatment failure in 14-18% of people with refractory status epilepticus. Tolerance develops rapidly to the anticonvulsant effect, and the dose may need to be increased by several times to maintain anticonvulsant therapeutic effects. With prolonged use, tolerance and tachyphylaxis can occur and the elimination half-life may increase, up to days. There is evidence buccal and intranasal midazolam is easier to administer and more effective than rectally administered diazepam in the emergency control of seizures.
Intravenous midazolam is indicated for procedural sedation (often in combination with an opioid, such as fentanyl), for preoperative sedation, for the induction of general anaesthesia, and for sedation of people who are ventilated in critical care units. Midazolam is superior to diazepam in impairing memory of endoscopy procedures, but propofol has a quicker recovery time and a better memory-impairing effect. It is the most popular benzodiazepine in the intensive care unit (ICU) because of its short elimination half-life, combined with its water solubility and its suitability for continuous infusion. However, for long-term sedation, lorazepam is preferred due to its long duration of action, and propofol has advantages over midazolam when used in the ICU for sedation, such as shorter weaning time and earlier tracheal extubation.
Midazolam is sometimes used in neonatal intensive care units. When used, additional caution is required in newborns; midazolam should not be used for longer than 72 hours due to risks of tachyphylaxis, and the possibility of development of a benzodiazepine withdrawal syndrome, as well as neurological complications. Bolus injections should be avoided due to the increased risk of cardiovascular depression, as well as neurological complications. Midazolam is also sometimes used in newborns who are receiving mechanical ventilation, although morphine is preferred, owing to its better safety profile for this indication.
Sedation using midazolam can be used to relieve anxiety and manage behaviour in children undergoing dental treatment.
Midazolam, in combination with an antipsychotic drug, is indicated for the acute management of schizophrenia when it is associated with aggressive or out-of-control behaviour.
In the final stages of end-of-life care, midazolam is routinely used at low doses via subcutaneous injection to help with agitation, myoclonus, restlessness or anxiety in the last hours or days of life. At higher doses during the last weeks of life, midazolam is considered a first line agent in palliative continuous deep sedation therapy when it is necessary to alleviate intolerable suffering not responsive to other treatments, but the need for this is rare.
Routes of administration of midazolam can be oral, intranasal, buccal, intravenous, and intramuscular.
Benzodiazepines require special precaution if used in the elderly, during pregnancy, in children, in alcohol- or other drug-dependent individuals or those with comorbid psychiatric disorders. Additional caution is required in critically ill patients, as accumulation of midazolam and its active metabolites may occur. Kidney or liver impairments may slow down the elimination of midazolam leading to prolonged and enhanced effects. Contraindications include hypersensitivity, acute narrow-angle glaucoma, shock, hypotension, or head injury. Most are relative contraindications.
Refer to Long-Term Effects of Benzodiazepines.
Side effects of midazolam in the elderly are listed above. People experiencing amnesia as a side effect of midazolam are generally unaware their memory is impaired, unless they had previously known it as a side effect.
Long-term use of benzodiazepines has been associated with long-lasting deficits of memory, and show only partial recovery six months after stopping benzodiazepines. It is unclear whether full recovery occurs after longer periods of abstinence. Benzodiazepines can cause or worsen depression. Paradoxical excitement occasionally occurs with benzodiazepines, including a worsening of seizures. Children and elderly individuals or those with a history of excessive alcohol use and individuals with a history of aggressive behaviour or anger are at increased risk of paradoxical effects. Paradoxical reactions are particularly associated with intravenous administration. After night-time administration of midazolam, residual ‘hangover’ effects, such as sleepiness and impaired psychomotor and cognitive functions, may persist into the next day. This may impair the ability of users to drive safely and may increase the risk of falls and hip fractures. Sedation, respiratory depression and hypotension due to a reduction in systematic vascular resistance, and an increase in heart rate can occur. If intravenous midazolam is given too quickly, hypotension may occur. A “midazolam infusion syndrome” may result from high doses, and is characterised by delayed arousal hours to days after discontinuation of midazolam, and may lead to an increase in the length of ventilatory support needed.
In susceptible individuals, midazolam has been known to cause a paradoxical reaction, a well-documented complication with benzodiazepines. When this occurs, the individual may experience anxiety, involuntary movements, aggressive or violent behaviour, uncontrollable crying or verbalization, and other similar effects. This seems to be related to the altered state of consciousness or disinhibition produced by the drug. Paradoxical behaviour is often not recalled by the patient due to the amnesia-producing properties of the drug. In extreme situations, flumazenil can be administered to inhibit or reverse the effects of midazolam. Antipsychotic medications, such as haloperidol, have also been used for this purpose.
Midazolam is known to cause respiratory depression. In healthy humans, 0.15 mg/kg of midazolam may cause respiratory depression, which is postulated to be a central nervous system (CNS) effect. When midazolam is administered in combination with fentanyl, the incidence of hypoxemia or apnoea becomes more likely.
Although the incidence of respiratory depression/arrest is low (0.1-0.5%) when midazolam is administered alone at normal doses, the concomitant use with CNS acting drugs, mainly analgesic opiates, may increase the possibility of hypotension, respiratory depression, respiratory arrest, and death, even at therapeutic doses. Potential drug interactions involving at least one CNS depressant were observed for 84% of midazolam users who were subsequently required to receive the benzodiazepine antagonist flumazenil. Therefore, efforts directed toward monitoring drug interactions and preventing injuries from midazolam administration are expected to have a substantial impact on the safe use of this drug.
Midazolam, when taken during the third trimester of pregnancy, may cause risk to the neonate, including benzodiazepine withdrawal syndrome, with possible symptoms including hypotonia, apnoeic spells, cyanosis, and impaired metabolic responses to cold stress. Symptoms of hypotonia and the neonatal benzodiazepine withdrawal syndrome have been reported to persist from hours to months after birth. Other neonatal withdrawal symptoms include hyperexcitability, tremor, and gastrointestinal upset (diarrhoea or vomiting). Breastfeeding by mothers using midazolam is not recommended.
Additional caution is required in the elderly, as they are more sensitive to the pharmacological effects of benzodiazepines, metabolise them more slowly, and are more prone to adverse effects, including drowsiness, amnesia (especially anterograde amnesia), ataxia, hangover effects, confusion, and falls.
A benzodiazepine dependence occurs in about one-third of individuals who are treated with benzodiazepines for longer than 4 weeks, which typically results in tolerance and benzodiazepine withdrawal syndrome when the dose is reduced too rapidly. Midazolam infusions may induce tolerance and a withdrawal syndrome in a matter of days. The risk factors for dependence include dependent personality, use of a benzodiazepine that is short-acting, high potency and long-term use of benzodiazepines. Withdrawal symptoms from midazolam can range from insomnia and anxiety to seizures and psychosis. Withdrawal symptoms can sometimes resemble a person’s underlying condition. Gradual reduction of midazolam after regular use can minimise withdrawal and rebound effects. Tolerance and the resultant withdrawal syndrome may be due to receptor down-regulation and GABAA receptor alterations in gene expression, which causes long-term changes in the function of the GABAergic neuronal system.
Chronic users of benzodiazepine medication who are given midazolam experience reduced therapeutic effects of midazolam, due to tolerance to benzodiazepines. Prolonged infusions with midazolam results in the development of tolerance; if midazolam is given for a few days or more a withdrawal syndrome can occur. Therefore, preventing a withdrawal syndrome requires that a prolonged infusion be gradually withdrawn, and sometimes, continued tapering of dose with an oral long-acting benzodiazepine such as clorazepate dipotassium. When signs of tolerance to midazolam occur during intensive care unit sedation the addition of an opioid or propofol is recommended. Withdrawal symptoms can include irritability, abnormal reflexes, tremors, clonus, hypertonicity, delirium and seizures, nausea, vomiting, diarrhoea, tachycardia, hypertension, and tachypnoea. In those with significant dependence, sudden discontinuation may result in withdrawal symptoms such as status epilepticus that may be fatal.
Refer to Benzodiazepine Overdose.
A midazolam overdose is considered a medical emergency and generally requires the immediate attention of medical personnel. Benzodiazepine overdose in healthy individuals is rarely life-threatening with proper medical support; however, the toxicity of benzodiazepines increases when they are combined with other CNS depressants such as alcohol, opioids, or tricyclic antidepressants. The toxicity of benzodiazepine overdose and risk of death is also increased in the elderly and those with obstructive pulmonary disease or when used intravenously. Treatment is supportive; activated charcoal can be used within an hour of the overdose. The antidote for an overdose of midazolam (or any other benzodiazepine) is flumazenil. While effective in reversing the effects of benzodiazepines it is not used in most cases as it may trigger seizures in mixed overdoses and benzodiazepine dependent individuals.
Symptoms of midazolam overdose can include:
Concentrations of midazolam or its major metabolite, 1-hydroxymidazolam glucuronide, may be measured in plasma, serum, or whole blood to monitor for safety in those receiving the drug therapeutically, to confirm a diagnosis of poisoning in hospitalised patients, or to assist in a forensic investigation of a case of fatal overdosage. Patients with renal dysfunction may exhibit prolongation of elimination half-life for both the parent drug and its active metabolite, with accumulation of these two substances in the bloodstream and the appearance of adverse depressant effects.
Protease inhibitors, nefazodone, sertraline, grapefruit, fluoxetine, erythromycin, diltiazem, clarithromycin inhibit the metabolism of midazolam, leading to a prolonged action. St John’s wort, rifapentine, rifampin, rifabutin, phenytoin enhance the metabolism of midazolam leading to a reduced action. Sedating antidepressants, antiepileptic drugs such as phenobarbital, phenytoin and carbamazepine, sedative antihistamines, opioids, antipsychotics and alcohol enhance the sedative effects of midazolam. Midazolam is metabolised almost completely by cytochrome P450-3A4. Atorvastatin administration along with midazolam results in a reduced elimination rate of midazolam. St John’s wort decreases the blood levels of midazolam. Grapefruit juice reduces intestinal 3A4 and results in less metabolism and higher plasma concentrations.
Midazolam is a short-acting benzodiazepine in adults with an elimination half-life of 1.5-2.5 hours. In the elderly, as well as young children and adolescents, the elimination half-life is longer. Midazolam is metabolised into an active metabolite alpha1-hydroxymidazolam. Age-related deficits, renal and liver status affect the pharmacokinetic factors of midazolam as well as its active metabolite. However, the active metabolite of midazolam is minor and contributes to only 10 percent of biological activity of midazolam. Midazolam is poorly absorbed orally, with only 50% of the drug reaching the bloodstream. Midazolam is metabolised by cytochrome P450 (CYP) enzymes and by glucuronide conjugation. The therapeutic as well as adverse effects of midazolam are due to its effects on the GABAA receptors; midazolam does not activate GABAA receptors directly but, as with other benzodiazepines, it enhances the effect of the neurotransmitter GABA on the GABAA receptors (↑ frequency of Cl- channel opening) resulting in neural inhibition. Almost all of the properties can be explained by the actions of benzodiazepines on GABAA receptors. This results in the following pharmacological properties being produced: sedation, induction of sleep, reduction in anxiety, anterograde amnesia, muscle relaxation and anticonvulsant effects.
Midazolam is available as a generic medication.
Midazolam is available in the United States as a syrup or as an injectable solution.
Dormicum brand midazolam is marketed by Roche as white, oval, 7.5-mg tablets in boxes of two or three blister strips of 10 tablets, and as blue, oval, 15-mg tablets in boxes of two (Dormonid 3x) blister strips of 10 tablets. The tablets are imprinted with “Roche” on one side and the dose of the tablet on the other side. Dormicum is also available as 1-, 3-, and 10-ml ampoules at a concentration of 5 mg/ml. Another manufacturer, Novell Pharmaceutical Laboratories, makes it available as Miloz in 3- and 5-ml ampoules. Midazolam is the only water-soluble benzodiazepine available. Another maker is Roxane Laboratories; the product in an oral solution, Midazolam HCl Syrup, 2 mg/ml clear, in a red to purplish-red syrup, cherry in flavour. It becomes soluble when the injectable solution is buffered to a pH of 2.9-3.7. Midazolam is also available in liquid form. It can be administered intramuscularly, intravenously, intrathecally, intranasally, buccally, or orally.
In the Netherlands, midazolam is a List II drug of the Opium Law. Midazolam is a Schedule IV drug under the Convention on Psychotropic Substances. In the United Kingdom, midazolam is a Schedule 3/Class C controlled drug. In the United States, midazolam (DEA number 2884) is on the Schedule IV list of the Controlled Substances Act as a non-narcotic agent with low potential for abuse.
In 2011, the European Medicines Agency (EMA) granted a marketing authorisation for a buccal application form of midazolam, sold under the trade name Buccolam. Buccolam was approved for the treatment of prolonged, acute, convulsive seizures in people from three months to less than 18 years of age. This was the first application of a paediatric-use marketing authorisation.
The drug has been introduced for use in executions by lethal injection in certain jurisdictions in the United States in combination with other drugs. It was introduced to replace pentobarbital after the latter’s manufacturer disallowed that drug’s use for executions. Midazolam acts as a sedative but will fail to render the condemned prisoner unconscious, at which time vecuronium bromide and potassium chloride are administered, stopping the prisoner’s breathing and heart, respectively. Due to the fact that the condemned prisoner is not unconscious but merely sedated, two very different things, those following two drugs can cause extreme pain and panic in the soon to die prisoner.
Midazolam has been used as part of a three-drug cocktail, with vecuronium bromide and potassium chloride in Florida and Oklahoma prisons. Midazolam has also been used along with hydromorphone in a two-drug protocol in Ohio and Arizona.
The usage of midazolam in executions became controversial after condemned inmate Clayton Lockett apparently regained consciousness and started speaking midway through his 2014 execution when the state of Oklahoma attempted to execute him with an untested three-drug lethal injection combination using 100 mg of midazolam. Prison officials reportedly discussed taking him to a hospital before he was pronounced dead of a heart attack 40 minutes after the execution began. An observing doctor stated that Lockett’s vein had ruptured. It is not clear whether his death was caused by one or more of the drugs or to a problem in the administration procedure, nor is it clear what quantities of vecuronium bromide and potassium chloride were released to his system before the execution was cancelled.
The state of Florida used midazolam to execute William Frederick Happ in October 2013.
The state of Ohio used midazolam in the execution of Dennis McGuire in January 2014; it took McGuire 24 minutes to die after the procedure started, and he gasped and appeared to be choking during that time, leading to questions about the dosing and timing of the drug administration, as well as the choice of drugs.
The execution of Ronald Bert Smith in the state of Alabama on 08 December 2016, “went awry soon after (midazolam) was administered” again putting the effectiveness of the drug in question.
In October 2016, the state of Ohio announced that it would resume executions in January 2017, using a formulation of midazolam, vecuronium bromide, and potassium chloride, but this was blocked by a Federal judge. On 26 July 2017, Ronald Phillips was executed with a three-drug cocktail including midazolam after the Supreme Court refused to grant a stay. Prior to this, the last execution in Ohio had been that of Dennis McGuire. Murderer Gary Otte’s lawyers unsuccessfully challenged his Ohio execution, arguing that midazolam might not protect him from serious pain when the other drugs are administered. He died without incident in about 14 minutes on 13 September 2017.
On 24 April 2017, the state of Arkansas carried out a double-execution of Jack Harold Jones, 52, and Marcel Williams, 46. The state of Arkansas attempted to execute eight people before its supply of midazolam expired on 30 April 2017. Two of them were granted a stay of execution, and another, Ledell T. Lee, 51, was executed on 20 April 2017.
On 28 October 2021, the state of Oklahoma carried out the execution of inmate John Marion Grant, 60, using midazolam as part of its three-drug cocktail hours after the US Supreme Court ruled to lift a stay of execution for Oklahoma death row inmates. The execution was the state’s first since 2015. Witnesses to the execution said that when the first drug, midazolam, began to flow at 4:09 pm, Grant started convulsing about two dozen times and vomited. Grant continued breathing, and a member of the execution team wiped the vomit off his face. At 4:15 pm., officials said Grant was unconscious, and he was pronounced dead at 4:21 pm.
In Glossip v. Gross, attorneys for three Oklahoma inmates argued that midazolam could not achieve the level of unconsciousness required for surgery, meaning severe pain and suffering was likely. They argued that midazolam was cruel and unusual punishment and thus contrary to the Eighth Amendment to the United States Constitution. In June 2015, the US Supreme Court ruled that they had failed to prove that midazolam was cruel and unusual when compared to known, available alternatives.
The state of Nevada is also known to use midazolam in execution procedures. In July 2018, one of the manufacturers accused state officials of obtaining the medication under false pretences. This incident was the first time a drug company successfully, though temporarily, halted an execution. A previous attempt in 2017, to halt an execution in the state of Arizona by another drug manufacturer was not successful.

He captained the international side in 31 of his 39 Test matches, winning 17 and losing only 4. He was the President of the Marylebone Cricket Club (MCC) in 2007-2008. Since his retirement from professional cricket he has pursued a career as a writer and psychoanalyst, serving as President of the British Psychoanalytical Society 2008-2010. In 2015, an article in the Bleacher Report ranked Brearley as England’s greatest ever cricket captain.
He is married to Mana Sarabhai who is from Ahmedabad, India and they have two children together.
Milan Popović (1924 to 28 April 2012) was a renowned Serbian psychiatrist-psychoanalyst, a full professor of the University of Belgrade Faculty of Philosophy.
He was born in 1924 in Belgrade, Serbia. He graduated from the University of Belgrade School of Medicine, specialized neuropsychiatry and was awarded a doctor’s degree with the theme “Group psychotherapy of the schizophrenic in hospital conditions”. He was elected associate professor of the Faculty of Philosophy of Belgrade University in 1972 and full professor in 1980.
Milan Popović is a pioneer in developing the group psychiatry in Serbia and opening psychiatric departments towards the society. He is a founder of “Psychoanalytical psychotherapy school” at post graduated studies of the Faculty of Medicine in Belgrade.
He is a teacher of many generations of psychiatrists, psychologists and sociologists in Serbia. He has given an important contribution to the development of psychiatry in the country, especially the development of psychotherapy and social psychiatry, truthfully representing domestic achievements abroad.
Amisulpride is an antiemetic and antipsychotic medication used at lower doses intravenously to prevent and treat postoperative nausea and vomiting; and at higher doses by mouth to treat schizophrenia and acute psychotic episodes.
It is sold under the brand names Barhemsys (as an antiemetic) and Solian, Socian, Deniban and others (as an antipsychotic). It is also used to treat dysthymia.
It is usually classed with the atypical antipsychotics. Chemically it is a benzamide and like other benzamide antipsychotics, such as sulpiride, it is associated with a high risk of elevating blood levels of the lactation hormone, prolactin (thereby potentially causing the absence of the menstrual cycle, breast enlargement, even in males, breast milk secretion not related to breastfeeding, impaired fertility, impotence, breast pain, etc.), and a low risk, relative to the typical antipsychotics, of causing movement disorders.
Amisulpride is indicated for use in the US in adults for the prevention of postoperative nausea and vomiting (PONV), either alone or in combination with an antiemetic of a different class; and to treat PONV in those who have received antiemetic prophylaxis with an agent of a different class or have not received prophylaxis.
Amisulpride is believed to work by blocking, or antagonising, the dopamine D2 receptor, reducing its signalling. The effectiveness of amisulpride in treating dysthymia and the negative symptoms of schizophrenia is believed to stem from its blockade of the presynaptic dopamine D2 receptors. These presynaptic receptors regulate the release of dopamine into the synapse, so by blocking them amisulpride increases dopamine concentrations in the synapse. This increased dopamine concentration is theorised to act on dopamine D1 receptors to relieve depressive symptoms (in dysthymia) and the negative symptoms of schizophrenia.
It was introduced by Sanofi-Aventis in the 1990s. Its patent expired by 2008, and generic formulations became available. It is marketed in all English-speaking countries except for Canada. A New York City based company, LB Pharmaceuticals, has announced the ongoing development of LB-102, also known as N-methyl amisulpride, an antipsychotic specifically targeting the United States. A poster presentation at European Neuropsychopharmacology seems to suggest that this version of amisulpride, known as LB-102 displays the same binding to D2, D3 and 5HT7 that amisulpride does.
The US Food and Drug Administration (FDA) approved amisulpride based on evidence from four clinical trials of 2323 subjects undergoing surgery or experiencing nausea and vomiting after the surgery. The trials were conducted at 80 sites in the United States, Canada and Europe.
Two trials (Trials 1 and 2) enrolled subjects scheduled to have surgery. Subjects were randomly assigned to receive either amisulpride or a placebo drug at the beginning of general anaesthesia. In Trial 1, subjects received amisulpride or placebo alone, and in Trial 2, they received amisulpride or placebo in combination with one medication approved for prevention of nausea and vomiting. Neither the subjects nor the health care providers knew which treatment was being given until after the trial was complete.
The trials counted the number of subjects who had no vomiting and did not use additional medications for nausea or vomiting in the first day (24 hours) after the surgery. The results then compared amisulpride to placebo.
The other two trials (Trials 3 and 4) enrolled subjects who were experiencing nausea and vomiting after surgery. In Trial 3, subjects did not receive any medication to prevent nausea and vomiting before surgery and in Trial 4 they received the medication, but the treatment did not work. In both trials, subjects were randomly assigned to receive either amisulpride or placebo. Neither the subjects nor the health care providers knew which treatment was being given until after the trial was complete.
The trials counted the number of subjects who had no vomiting and did not use additional medications for nausea or vomiting in the first day (24 hours) after the treatment. The trial compared amisulpride to placebo.
Although according to other studies it appears to have comparable efficacy to olanzapine in the treatment of schizophrenia. Amisulpride augmentation, similarly to sulpiride augmentation, has been considered a viable treatment option (although this is based on low-quality evidence) in clozapine-resistant cases of schizophrenia. Another recent study concluded that amisulpride is an appropriate first-line treatment for the management of acute psychosis.
Amisulpride is indicated for use in the United States in adults for the prevention of postoperative nausea and vomiting (PONV), either alone or in combination with an antiemetic of a different class; and to treat PONV in those who have received antiemetic prophylaxis with an agent of a different class or have not received prophylaxis.
Amisulpride’s use is contraindicated in the following disease states:
Neither is it recommended to use amisulpride in patients with hypersensitivities to amisulpride or the excipients found in its dosage form.
Hyperprolactinaemia results from antagonism of the D2 receptors located on the lactotrophic cells found in the anterior pituitary gland. Amisulpride has a high propensity for elevating plasma prolactin levels as a result of its poor blood-brain barrier penetrability and hence the resulting greater ratio of peripheral D2 occupancy to central D2 occupancy. This means that to achieve the sufficient occupancy (~60–80%) of the central D2 receptors in order to elicit its therapeutic effects a dose must be given that is enough to saturate peripheral D2 receptors including those in the anterior pituitary.
The British National Formulary recommends a gradual withdrawal when discontinuing antipsychotics to avoid acute withdrawal syndrome or rapid relapse. Symptoms of withdrawal commonly include nausea, vomiting, and loss of appetite. Other symptoms may include restlessness, increased sweating, and trouble sleeping. Less commonly there may be a feeling of the world spinning, numbness, or muscle pains. Symptoms generally resolve after a short period of time.
There is tentative evidence that discontinuation of antipsychotics can result in psychosis. It may also result in reoccurrence of the condition that is being treated. Rarely tardive dyskinesia can occur when the medication is stopped.
Torsades de pointes is common in overdose. Amisulpride is moderately dangerous in overdose (with the TCAs being very dangerous and the SSRIs being modestly dangerous).
Amisulpride should not be used in conjunction with drugs that prolong the QT interval (such as citalopram, bupropion, clozapine, tricyclic antidepressants, sertindole, ziprasidone, etc.), reduce heart rate and those that can induce hypokalaemia. Likewise it is imprudent to combine antipsychotics due to the additive risk for tardive dyskinesia and neuroleptic malignant syndrome.
Amisulpride functions primarily as a dopamine D2 and D3 receptor antagonist. It has high affinity for these receptors with dissociation constants of 3.0 and 3.5 nM, respectively. Although standard doses used to treat psychosis inhibit dopaminergic neurotransmission, low doses preferentially block inhibitory presynaptic autoreceptors. This results in a facilitation of dopamine activity, and for this reason, low-dose amisulpride has also been used to treat dysthymia.
Amisulpride and its relatives sulpiride, levosulpiride, and sultopride have been shown to bind to the high-affinity GHB receptor at concentrations that are therapeutically relevant (IC50 = 50 nM for amisulpride).
Amisulpride, sultopride and sulpiride respectively present decreasing in vitro affinities for the D2 receptor (IC50 = 27, 120 and 181 nM) and the D3 receptor (IC50 = 3.6, 4.8 and 17.5 nM).
Though it was long widely assumed that dopaminergic modulation is solely responsible for the respective antidepressant and antipsychotic properties of amisulpride, it was subsequently found that the drug also acts as a potent antagonist of the serotonin 5-HT7 receptor (Ki = 11.5 nM). Several of the other atypical antipsychotics such as risperidone and ziprasidone are potent antagonists at the 5-HT7 receptor as well, and selective antagonists of the receptor show antidepressant properties themselves. To characterise the role of the 5-HT7 receptor in the antidepressant effects of amisulpride, a study prepared 5-HT7 receptor knockout mice. The study found that in two widely used rodent models of depression, the tail suspension test, and the forced swim test, those mice did not exhibit an antidepressant response upon treatment with amisulpride. These results suggest that 5-HT7 receptor antagonism mediates the antidepressant effects of amisulpride.
Amisulpride also appears to bind with high affinity to the serotonin 5-HT2B receptor (Ki = 13 nM), where it acts as an antagonist. The clinical implications of this, if any, are unclear. In any case, there is no evidence that this action mediates any of the therapeutic effects of amisulpride.
Amisulpride shows stereoselectivity in its actions. Aramisulpride ((R)-amisulpride) has higher affinity for the 5-HT7 receptor (Ki = 47 nM vs. 1,900 nM) while esamisulpride ((S)-amisulpride) has higher affinity for the D2 receptor (4.0 nM vs. 140 nM). An 85:15 ratio of aramisulpride to esamisulpride (SEP-4199) which provides more balanced 5-HT7 and D2 receptor antagonism than racemic amisulpride (50:50 ratio of enantiomers) is under development for the treatment of bipolar depression.
Brand names include: Amazeo, Amipride (AU), Amival, Solian (AU, IE, RU, UK, ZA), Soltus, Sulpitac (IN), Sulprix (AU), Midora (RO) and Socian (BR).
Amisulpride was not approved by the Food and Drug Administration for use in the United States until February 2020, but it is used in Europe, Israel, Mexico, India, New Zealand and Australia to treat psychosis and schizophrenia.
An IV formulation of Amisulpride was approved for the treatment of postoperative nausea and vomiting (“PONV”) in the United States in February 2020.
