Brovarin
Bromisoval ( INN), commonly known as bromovalerylurea, is a hypnotic and sedative of the bromoureide group discovered by Knoll in 1907 and patented in 1909. It is marketed over the counter in Asia under various trade names (such as ''Brovarin''), usually in combination with nonsteroidal anti-inflammatory drug Non-steroidal anti-inflammatory drugs (NSAID) are members of a therapeutic drug class which reduces pain, decreases inflammation, decreases fever, and prevents blood clots. Side effects depend on the specific drug, its dose and duration of ...s. Chronic use of bromisoval has been associated with bromine poisoning. Bromisoval can be prepared by bromination of isovaleric acid by the Hell-Volhard-Zelinsky reaction followed by reaction with urea.

Carbromal
Carbromal is a hypnotic/sedative originally synthesized in 1909 by Bayer and subsequently marketed as Adalin. The drug was later sold by Parke-Davis in combination with pentobarbital, under the name Carbrital. Synthesis Diethylmalonic acid [510-20-3] (1) is decarboxylated to 2-ethylvaleric acid [20225-24-5] (2). The Hell-Volhard-Zelinsky reaction converts this to 2-Bromo-2-Ethylbutyryl Bromide [26074-53-3] (3). Reaction with urea with affords carbromal (4).

Over-the-counter Drug
Over-the-counter (OTC) drugs are medicines sold directly to a consumer without a requirement for a prescription from a healthcare professional, as opposed to prescription drugs, which may be supplied only to consumers possessing a valid prescription. In many countries, OTC drugs are selected by a regulatory agency to ensure that they contain ingredients that are safe and effective when used without a physician's care. OTC drugs are usually regulated according to their active pharmaceutical ingredient (API) rather than final products. By regulating APIs instead of specific drug formulations, governments allow manufacturers the freedom to formulate ingredients, or combinations of ingredients, into proprietary mixtures. The term ''over-the-counter'' (''OTC'') refers to a medication that can be purchased without a medical prescription. In contrast, prescription drugs require a prescription from a doctor or other health care professional and should only be used by the prescribed ...

Sedatives
A sedative or tranquilliser is a substance that induces sedation by reducing irritability or excitement. They are CNS depressants and interact with brain activity causing its deceleration. Various kinds of sedatives can be distinguished, but the majority of them affect the neurotransmitter gamma-aminobutyric acid (GABA). In spite of the fact that each sedative acts in its own way, most produce relaxing effects by increasing GABA activity. This group is related to hypnotics. The term ''sedative'' describes drugs that serve to calm or relieve anxiety, whereas the term ''hypnotic'' 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. Sedatives can be used to produce an overly-calming effect (alcohol being the most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypnotics
Hypnotic (from Greek ''Hypnos'', sleep), or soporific drugs, commonly known as sleeping pills, are a class of (and umbrella term for) psychoactive drugs whose primary function is to induce sleep (or surgical anesthesiaWhen used in anesthesia to produce and maintain unconsciousness, "sleep" is metaphorical as there are no regular sleep stages or cyclical natural states; patients rarely recover from anesthesia feeling refreshed and with renewed energy. The word is also used in art.) and to treat insomnia (sleeplessness). This group of drugs is related to sedatives''.

Apronal
Apronal (brand name Sedormid), or apronalide, also known as allylisopropylacetylurea or allylisopropylacetylcarbamide, is a hypnotic/sedative drug of the ureide (acylurea) group synthesized in 1926 by Hoffmann-La Roche that is no longer used except in Japan (See Japanese article). Though it is not a barbiturate, apronalide is similar in structure to the barbiturates (being an open-chain carbamide instead of having a heterocyclic ring). In accordance, it is similar in action to the barbiturates, although considerably milder in comparison (formerly used as a daytime sedative at doses of 1 to 2 grams every 3 to 4 hours). Upon the finding that it caused patients to develop thrombocytopenic purpura, apronalide was withdrawn from clinical use.

Acecarbromal
Acecarbromal (INN) (brand names Sedamyl, Abasin, Carbased, Paxarel, Sedacetyl, numerous others), also known as acetylcarbromal and acetyladalin, is a hypnotic and sedative drug of the ureide (acylurea) group discovered by Bayer in 1917 that was formerly marketed in the United States and Europe. It is also used in combination with extract of quebracho and vitamin E as a treatment for erectile dysfunction under the brand name Afrodor in Europe. Acecarbromal is structurally related to the barbiturates, which are basically cyclized ureas. Prolonged use is not recommended as it can cause bromine poisoning.

Urea
Urea, also known as carbamide, is an organic compound with chemical formula . This amide has two amino groups (–) joined by a carbonyl functional group (–C(=O)–). It is thus the simplest amide of carbamic acid. Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. It is a colorless, odorless solid, highly soluble in water, and practically non-toxic ( is 15 g/kg for rats). Dissolved in water, it is neither acidic nor alkaline. The body uses it in many processes, most notably nitrogen excretion. The liver forms it by combining two ammonia molecules () with a carbon dioxide () molecule in the urea cycle. Urea is widely used in fertilizers as a source of nitrogen (N) and is an important raw material for the chemical industry. In 1828 Friedrich Wöhler discovered that urea can be produced from inorganic starting materials, which was an important conceptual milestone ...

Bromine
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest element in group 17 of the periodic table (halogens) and is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826), its name was derived from the Ancient Greek (bromos) meaning "stench", referring to its sharp and pungent smell. Elemental bromine is very reactive and thus does not occur as a native element in nature but it occurs in colourless soluble crystalline mineral halide salts, analogous to table salt. In fact, bromine and all the halogens are so reactive that they form bonds in pairs—never in single atoms. While it is rather rare in the Earth's crust, the high solubility of the bromide ion (Br) has caused its accumulation in the oceans. Commercial ...

Nonsteroidal Anti-inflammatory Drug
Non-steroidal anti-inflammatory drugs (NSAID) are members of a therapeutic drug class which reduces pain, decreases inflammation, decreases fever, and prevents blood clots. Side effects depend on the specific drug, its dose and duration of use, but largely include an increased risk of gastrointestinal ulcers and bleeds, heart attack, and kidney disease. The term ''non-steroidal'', common from around 1960, distinguishes these drugs from corticosteroids, which during the 1950s had acquired a bad reputation due to overuse and side-effect problems after their initial introduction in 1948. NSAIDs work by inhibiting the activity of cyclooxygenase enzymes (the COX-1 and COX-2 isoenzymes). In cells, these enzymes are involved in the synthesis of key biological mediators, namely prostaglandins, which are involved in inflammation, and thromboxanes, which are involved in blood clotting. There are two general types of NSAIDs available: non-selective, and COX-2 selective. Most N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
