Methylphenobarbital
Methylphenobarbital (INN), also known as mephobarbital (USAN, JAN) and mephobarbitone ( BAN), marketed under brand names such as Mebaral, Mephyltaletten, Phemiton, and Prominal, is a drug which is a barbiturate derivative and is used primarily as an anticonvulsant, but also as a sedative and anxiolytic. It is the ''N''-methylated analogue of phenobarbital and has similar indications, therapeutic value, and tolerability. Approval history * 1935 – Mebaral was introduced by Winthrop Pharmaceuticals. * 2001 – Methylphenobarbital discontinued in the UK. * 2003 – Mebaral was acquired by Ovation Pharmaceuticals (a specialty pharmaceutical company that acquired under-promoted branded pharmaceutical products). * 2009 – Ovation was acquired by Lundbeck, which now markets Mebaral. * 2012 – Lundbeck announced that they were abandoning the product in the US as of January 6, 2012. The stated reason was because "the company thoroughly evaluated all avenues for keeping Mebaral ava ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Barbiturates have largely been replaced by benzodiazepines and nonbenzodiazepines ("Z-drugs") in routine medical practice, particularly in the treatment of anxiety disorders and insomnia, because of the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 ...

Methyl Compounds
In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula (whereas normal methane has the formula ). In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in most molecules. While the methyl group is usually part of a larger molecule, bonded to the rest of the molecule by a single covalent bond (), it can be found on its own in any of three forms: methanide anion (), methylium cation () or methyl radical (). The anion has eight valence electrons, the radical seven and the cation six. All three forms are highly reactive and rarely observed. Methyl cation, anion, and radical Methyl cation The methylium cation () exists in the gas phase, but is otherwise not encountered. Some compounds are considered to be sources of the cation, and this simplification is used pervasively in organic chemistry. For exampl ...

Anticonvulsants
Anticonvulsants (also known as antiepileptic drugs, antiseizure drugs, or anti-seizure medications (ASM)) are a diverse group of pharmacological agents used in the treatment of epileptic seizures. Anticonvulsants are also used in the treatment of bipolar disorder and borderline personality disorder, since many seem to act as mood stabilizers, and for the treatment of neuropathic pain. Anticonvulsants suppress the uncontrolled and excessive firing of neurons during seizures and in doing so can also prevent the spread of the seizure within the brain. Conventional antiepileptic drugs have diverse mechanisms of action but many block sodium channels or enhance γ-aminobutyric acid ( GABA) function. Several antiepileptic drugs have multiple or uncertain mechanisms of action. Next to voltage-gated sodium channels and components of the GABA system, their targets include GABAA receptors, the GABA transporter type 1, and GABA transaminase. Additional targets include voltage-gated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenobarbital

Hexobarbital
Hexobarbital or hexobarbitone, sold both in acid and sodium salt forms as Citopan, Evipan, and Tobinal, is a barbiturate derivative having hypnotic and sedative effects. It was used in the 1940s and 1950s as an agent for inducing anesthesia for surgery, as well as a rapid-acting, short-lasting hypnotic for general use, and has a relatively fast onset of effects and short duration of action. Modern barbiturates (such as Thiopental) have largely supplanted the use of hexobarbital as an anesthetic, as they allow for better control of the depth of anesthesia. Hexobarbital is still used in some scientific research. History The chemical class of barbiturates are one of the oldest sedative-hypnotic agents known, dating back from the introduction of barbital in the early 20th century. In Hungary, hexobarbital (and other barbiturates) were regularly used as drugs by pregnant women attempting suicide. Hexobarbital was long thought to have potentially teratogenic and fetotoxic effects. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fever
Fever or pyrexia in humans is a symptom of an anti-infection defense mechanism that appears with Human body temperature, body temperature exceeding the normal range caused by an increase in the body's temperature Human body temperature#Fever, set point in the hypothalamus. There is no single agreed-upon upper limit for normal temperature: sources use values ranging between in humans. The increase in set point triggers increased muscle tone, muscle contractions and causes a feeling of cold or chills. This results in greater heat production and efforts to conserve heat. When the set point temperature returns to normal, a person feels hot, becomes Flushing (physiology), flushed, and may begin to Perspiration, sweat. Rarely a fever may trigger a febrile seizure, with this being more common in young children. Fevers do not typically go higher than . A fever can be caused by many medical conditions ranging from non-serious to life-threatening. This includes viral infection, viral, b ...

Somnolence
Somnolence (alternatively sleepiness or drowsiness) is a state of strong desire for sleep, or sleeping for unusually long periods (compare hypersomnia). It has distinct meanings and causes. It can refer to the usual state preceding falling asleep, the condition of being in a drowsy state due to circadian rhythm disorders, or a symptom of other health problems. It can be accompanied by lethargy, weakness and lack of mental agility. Somnolence is often viewed as a symptom rather than a disorder by itself. However, the concept of somnolence recurring at certain times for certain reasons constitutes various disorders, such as excessive daytime sleepiness, shift work sleep disorder, and others; and there are medical codes for somnolence as viewed as a disorder. Sleepiness can be dangerous when performing tasks that require constant concentration, such as driving a vehicle. When a person is sufficiently fatigued, microsleeps may be experienced. In individuals deprived of sleep, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drug Expiration
Drug expiration is the date after which a drug might not be suitable for use as manufactured. Consumers can determine the shelf life for a drug by checking its pharmaceutical packaging for an expiration date. Drugs which are past their shelf life can decompose and either be ineffective or even harmful. Standard advice from drug manufacturers and some health organizations is to dispose of drugs after the expiration date printed on the packaging. However, the published expiration date is not an absolute indication that a drug has spoiled. Consumers and organizations sometimes use expired drugs for medical treatment either as a cost saving measure or because they otherwise cannot access drugs which are not expired. Medical authorities find it difficult to discuss when consumers can safely use drugs after the printed expiration date because it is difficult to obtain clear information. Labeled expiration date versus true expiration Manufacturers print expiration dates on drug bottle la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
