Pentobarbitone
Pentobarbital (US) or pentobarbitone (British and Australian) is a short-acting barbiturate typically used as a sedative, a preanesthetic, and to control convulsions in emergencies. It can also be used for short-term treatment of insomnia but has been largely replaced by the benzodiazepine family of drugs. In high doses, pentobarbital causes death by respiratory arrest. It is used for veterinary euthanasia and is used by some US states and the United States federal government for executions of convicted criminals by lethal injection. In some countries and states, it is also used for physician-assisted suicide. Pentobarbital was widely abused beginning in the late 1930s and sometimes known as "yellow jackets" due to the yellow color of Nembutal-branded capsules. Pentobarbital was developed by Ernest H. Volwiler and at Abbott Laboratories in 1930. Uses Medical Typical applications for pentobarbital are sedative, short term hypnotic, preanesthetic, insomnia treatment, and con ...

Barbiturate
Barbiturates are a class of depressant, depressant drugs that are chemically derived from barbituric acid. They are effective when used medication, 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 recreational drug use, used recreationally for their anti-anxiety and sedative effects, and are thus prohibition of drugs, controlled in most countries due to the risks associated with such use. Barbiturates have largely been replaced by benzodiazepines and nonbenzodiazepines ("Z-drugs") in routine medical practice, particularly in the treatment of anxiety disorders and insomnia, because of the significantly lower risk of overdose, and the lack of an antidote for barbiturate overdose. Despite this, barbiturates are still in use for various purposes: in general anesthesia, epilepsy, treatment of acute migraines or cluster headaches, acute t ...

Oral Administration
Oral administration is a route of administration whereby a substance is taken through the Human mouth, mouth, swallowed, and then processed via the digestive system. This is a common route of administration for many medications. Oral administration can be easier and less painful than other routes of administration, such as Injection (medicine), injection. However, the onset of action is relatively low, and the effectiveness is reduced if it is not absorbed properly in the digestive system, or if it is broken down by digestive enzymes before it can reach the bloodstream. Some medications may cause gastrointestinal side effects, such as nausea or vomiting, when taken orally. Oral administration can also only be applied to conscious patients, and patients able to swallow. Terminology ''Per os'' (; ''P.O.'') is an adverbial phrase meaning literally from Latin "through the mouth" or "by mouth". The expression is used in medicine to describe a treatment that is taken orally (but not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lethal Injection
Lethal injection is the practice of injecting one or more drugs into a person (typically a barbiturate, paralytic, and potassium) for the express purpose of causing death. The main application for this procedure is capital punishment, but the term may also be applied in a broader sense to include euthanasia and other forms of suicide. The drugs cause the person to become unconscious, stops their breathing, and causes a heart arrhythmia, in that order. First developed in the United States, the method has become a legal means of execution in Mainland China, Thailand (since 2003), Guatemala, Taiwan, the Maldives, Nigeria, and Vietnam, though Guatemala abolished the death penalty for civilian cases in 2017 and has not conducted an execution since 2000, and the Maldives has never carried out an execution since its independence. Although Taiwan permits lethal injection as an execution method, no executions have been carried out in this manner; the same is true for Nigeria. Lethal ...

Refractory Disease
A disease is a particular abnormal condition that adversely affects the structure or function of all or part of an organism and is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies, and autoimmune disorders. In humans, ''disease'' is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, or death to the person affected, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structure and functio ...

Acute Liver Failure
Acute liver failure is the appearance of severe complications rapidly after the first signs (such as jaundice) of liver disease, and indicates that the liver has sustained severe damage (loss of function of 80–90% of liver cells). The complications are hepatic encephalopathy and impaired protein synthesis (as measured by the levels of serum albumin and the prothrombin time in the blood). The 1993 classification defines ''hyperacute'' as within 1 week, ''acute'' as 8–28 days, and ''subacute'' as 4–12 weeks; both the speed with which the disease develops and the underlying cause strongly affect outcomes. Signs and symptoms The main features of acute liver failure are rapid-onset jaundice, weakness, and eventually, changes in mental status that can begin as mild confusion but progress to coma, known as hepatic encephalopathy. Encephalopathy and cerebral edema In ALF, hepatic encephalopathy leads to cerebral edema, coma, brain herniation, and eventually death. Detection of e ...

Cerebral Ischemia
Brain ischemia is a condition in which there is insufficient bloodflow to the brain to meet metabolic demand. This leads to poor oxygen supply in the brain and may be temporary such as in transient ischemic attack or permanent in which there is death of brain tissue such as in cerebral infarction (ischemic stroke). The symptoms of brain ischemia reflect the anatomical region undergoing blood and oxygen deprivation, and may involve impairments in vision, body movement, and speaking. An interruption of blood flow to the brain for more than 10 seconds causes unconsciousness, and an interruption in flow for more than a few minutes generally results in irreversible brain damage. In 1974, Hossmann and Zimmermann demonstrated that ischemia induced in mammalian brains for up to an hour can be at least partially recovered. Accordingly, this discovery raised the possibility of intervening after brain ischemia before the damage becomes irreversible. Symptoms and signs The clinical pre ...

Reye's Syndrome
Reye syndrome is a rapidly worsening brain disease. Symptoms of Reye syndrome may include vomiting, personality changes, confusion, seizures, and loss of consciousness. While liver toxicity typically occurs in the syndrome, jaundice usually does not. Death occurs in 20–40% of those affected with Reye syndrome, and about a third of those who survive are left with a significant degree of brain damage. The cause of Reye syndrome is unknown. It usually begins shortly after recovery from a viral infection, such as influenza or chickenpox. About 90% of cases in children are associated with aspirin (salicylate) use. Inborn errors of metabolism are also a risk factor. The syndrome is associated with changes on blood tests such as a high blood ammonia level, low blood sugar level, and prolonged prothrombin time. Often, the liver is enlarged in those who have the syndrome. Prevention is typically by avoiding the use of aspirin in children. When aspirin was withdrawn for use in chi ...

Convulsions
A convulsion is a medical condition where the body muscles contract and relax rapidly and repeatedly, resulting in uncontrolled shaking. Because epileptic seizures typically include convulsions, the term ''convulsion'' is often used as a synonym for ''seizure''. However, not all epileptic seizures result in convulsions, and not all convulsions are caused by epileptic seizures. Non-epileptic convulsions have no relation with epilepsy, and are caused by non-epileptic seizures. Convulsions can be caused by epilepsy, infections (including a severe form of listeriosis which is caused by eating food contaminated by Listeria monocytogenes), brain trauma, or other medical conditions. They can also occur from an electric shock or improperly enriched air for scuba diving. The word ''fit'' is sometimes used to mean a convulsion or epileptic seizure. Signs and symptoms A person having a convulsion may experience several different symptoms, such as a brief blackout, confusion, drooling, l ...

Preanesthetic
A preanesthetic agent (or preanaesthetic agent) is a drug that is given before the administration of an anesthetic to make anesthesia more pleasant and safe. Examples Examples of preanesthetic agents are: * Acepromazine *atropine *diazepam *Scopolamine * Opioid analgesics, such as morphine, pethidine and buprenorphine. These drugs are used before the administration of an anesthetic to improve patient comfort, reduce possible side effects such as Postanesthetic shivering, relieve pain, and increase the effectiveness of the anesthetic. See also * Premedication Premedication is using medication before some other therapy (usually surgery or chemotherapy) to prepare for that forthcoming therapy. Typical examples include premedicating with a sedative or analgesic before surgery; using prophylactic (preven ... References {{reflist Anesthesia ...

Hypnotic
A hypnotic (from Ancient Greek, Greek ''Hypnos'', sleep), also known as a somnifacient or soporific, and commonly known as sleeping pills, are a class of psychoactive drugs whose primary function is to sleep induction, induce sleep and to treat insomnia (sleeplessness). This group of drugs is related to sedatives''. ''Whereas the term sedative describes drugs that serve to calm or Anxiolytic, relieve anxiety, the term hypnotic generally describes drugs whose main purpose is to initiate, sustain, or lengthen sleep. Because these two functions frequently overlap, and because drugs in this class generally produce dose-dependent effects (ranging from anxiolysis to loss of consciousness), they are often referred to collectively as sedative–hypnotic drugs. Hypnotic drugs are regularly prescribed for insomnia and other sleep disorders, with over 95% of insomnia patients being prescribed hypnotics in some countries. Many hypnotic drugs are habit-forming and—due to many factors kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abbott Laboratories
Abbott Laboratories is an American multinational medical devices and health care company with headquarters in Abbott Park, Illinois, in the United States. The company was founded by Chicago physician Wallace Calvin Abbott in 1888 to formulate known drugs; today, it sells medical devices, diagnostics, branded generic medicines and nutritional products.
