The term narcotic originally referred medically to any psychoactive compound with numbing or paralyzing properties. In the United States, it has since become associated with opiates and opioids, commonly morphine and heroin, as well as derivatives of many of the compounds found within raw opium latex. The primary three are morphine, codeine, and thebaine.
Substance-related disorders, also known as substance use disorders, can lead to large societal problems. It is found to be greatest in individuals ages 18–25, with a higher likelihood occurring in men compared to women, and urban residents compared to rural residents. On average, general medical facilities hold 22% of patients with substance-related disorders, possibly leading to psychiatric disorders later on. Over 50% of individuals with substance-related disorders will often have a "dual diagnosis," where they are diagnosed with the substance use, as well as a psychiatric diagnosis, the most common being major depression, personality disorder, anxiety disorders, and dysthymia.
Ethchlorvynol is a GABA-ergic sedative and hypnotic/soporific medication first developed by Pfizer in the 1950s. In the United States it was sold by Abbott Laboratories under the trade name Placidyl. Placidyl was available in 200 mg, 500 mg, and 750 mg strength gel filled capsules. While the 500 mg and 750 mg strength capsules were for use in reducing sleep latency, the 200 mg strength capsules were intended to be used to re-induce sleep in case of early awakening. Abbott discontinued production in 1999, due to it being replaced by the benzodiazepine family and its widespread abuse, after which Placidyl was available for about a year in the United States. Although, theoretically, ethchlorvynol could be manufactured for sale in the United States by another pharmaceutical company, no pharmaceutical company has chosen to do so. Individuals with a valid prescription for the substance may legally transport a reasonable amount of ethclorvynol with them into the United States.
Drug withdrawal, drug withdrawal syndrome, or substance withdrawal syndrome is the group of symptoms that occur upon the abrupt discontinuation or decrease in the intake of pharmaceutical or recreational drugs.
Stimulant psychosis is a mental disorder characterized by psychotic symptoms. It involves and typically occurs following an overdose or several day binge on psychostimulants, though one study reported occurrences at regularly prescribed doses in approximately 0.1% of individuals within the first several weeks after starting amphetamine or methylphenidate therapy. Methamphetamine psychosis, or long-term effects of stimulant use in the brain, depend upon genetics and may persist for some time.
Pharmacodynamics (PD) is the study of the biochemical and physiologic effects of drugs. The effects can include those manifested within animals, microorganisms, or combinations of organisms.
An induced coma – also known as a medically induced coma (MIC), barbiturate-induced coma, or drug-induced coma – is a temporary coma brought on by a controlled dose of an anesthetic drug, often a barbiturate such as pentobarbital or thiopental. Other intravenous anesthetic drugs such as midazolam or propofol may be used.
Substance dependence, also known as drug dependence, is a biopsychological situation whereby an individual's functionality is dependent on the necessitated re-consumption of a psychoactive substance because of an adaptive state that has developed within the individual from psychoactive substance consumption that results in the experience of withdrawal and that necessitates the re-consumption of the drug. A drug addiction, a distinct concept from substance dependence, is defined as compulsive, out-of-control drug use, despite negative consequences. An addictive drug is a drug which is both rewarding and reinforcing. ΔFosB, a gene transcription factor, is now known to be a critical component and common factor in the development of virtually all forms of behavioral and drug addictions, but not dependence.
In medicine, confusion is the quality or state of being bewildered or unclear. The term "acute mental confusion" is often used interchangeably with delirium in the International Statistical Classification of Diseases and Related Health Problems and the Medical Subject Headings publications to describe the pathology. These refer to the loss of orientation, or the ability to place oneself correctly in the world by time, location and personal identity. Mental confusion is sometimes accompanied by disordered consciousness and memory loss.
Biperiden, sold under the brand name Akineton among others, is a medication used to treat Parkinson disease, certain drug-induced movement disorders and Tourette Syndrome. It is not recommended for tardive dyskinesias. It is taken by mouth, injection into a vein, or muscle.
Organic brain syndrome, also known as organic brain disease, organic brain damage, organic brain disorder (OBD), organic mental syndrome, or organic mental disorder, refers to any syndrome or disorder of mental function whose cause is alleged to be known as organic (physiologic) rather than purely of the mind. These names are older and nearly obsolete general terms from psychiatry, referring to many physical disorders that cause impaired mental function. They are meant to exclude psychiatric disorders. Originally, the term was created to distinguish physical causes of mental impairment from psychiatric disorders, but during the era when this distinction was drawn, not enough was known about brain science for this cause-based classification to be more than educated guesswork labeled with misplaced certainty, which is why it has been deemphasized in current medicine. While mental or behavioural abnormalities related to the dysfunction can be permanent, treating the disease early may prevent permanent damage in addition to fully restoring mental functions. An organic cause to brain dysfunction is suspected when there is no indication of a clearly defined psychiatric or "inorganic" cause, such as a mood disorder.
Trihexyphenidyl is an antispasmodic drug used to treat stiffness, tremors, spasms, and poor muscle control. It is an agent of the antimuscarinic class and is often used in management of Parkinson's disease. It was approved by the FDA for the treatment of Parkinson's in the US in 2003.
Alcoholic hallucinosis is a complication of alcohol misuse in people with alcohol use disorder. It can occur during acute intoxication or withdrawal with the potential of having delirium tremens. Alcohol hallucinosis is a rather uncommon alcohol-induced psychotic disorder almost exclusively seen in chronic alcoholics who have many consecutive years of severe and heavy drinking during their lifetime. Alcoholic hallucinosis develops about 12 to 24 hours after the heavy drinking stops suddenly, and can last for days. It involves auditory and visual hallucinations, most commonly accusatory or threatening voices. The risk of developing alcoholic hallucinosis is increased by long-term heavy alcohol abuse and the use of other drugs. Descriptions of the condition date back to at least 1907.
Psychochemical warfare involves the use of psychopharmacological agents with the intention of incapacitating an adversary through the temporary induction of hallucinations or delirium. These agents, often called "drug weapons", are generally considered chemical weapons and, more narrowly, constitute a specific type of incapacitating agent.
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.
Perampanel, sold under the brand name Fycompa, is an anti-epileptic medication developed by Eisai Co. that is used in addition to other drugs to treat partial seizures and generalized tonic-clonic seizures for people older than twelve years. It was first approved in 2012, and as of 2016, its optimal role in the treatment of epilepsy relative to other drugs was not clear. It was the first antiepileptic drug in the class of selective non-competitive antagonist of AMPA receptors.
Substance-induced psychosis is a form of psychosis that is attributed to substance intoxication, withdrawal or recent consumption of psychoactive drugs. It is a psychosis that results from the effects of various substances, such as medicinal and nonmedicinal substances, legal and illegal drugs, chemicals, and plants. Various psychoactive substances have been implicated in causing or worsening psychosis in users.
A drug class is a group of medications and other compounds that have similar chemical structures, the same mechanism of action, similar modes of action, and/or are used to treat the similar diseases. The Food and Drug Administration (FDA) has worked on classifying and licensing new medications for many years. However, the FDA's Drug Evaluation and Research Center categorizes these new medications based on both their chemical and therapeutic class.
