Dichloralphenazone
Dichloralphenazone is a 1:2 mixture of antipyrine with chloral hydrate. In combination with paracetamol and isometheptene, it is the active ingredient of medications for migraine and tension headaches, including Epidrin and Midrin. Performance impairments are common with this drug and caution is advised, for example when driving motor vehicles. Additional uses of dichloralphenazone include sedation for the treatment of short-term insomnia, although there are probably better drug choices for the treatment of insomnia.

Midrin
Amidrine, Midrin, Nodolor, Duradrin, IDA, Migquin, Migrin-A, Migrazone or Epidrine is a combination drug consisting of paracetamol, dichloralphenazone and isometheptene used to treat migraines and severe, refractory headaches. Components * Paracetamol, also known as acetaminophen, is a common over-the-counter pain reliever and fever reducer. * Dichloralphenazone is a prodrug of two pharmacologically distinct agents: the sedative agent, chloral hydrate, as well as antipyrine, a non-steroidal anti-inflammatory drug that works to decrease inflammation. * Isometheptene is a sympathomimetic drug that works by inducing vasoconstriction, causing constriction of cerebral blood vessels and reducing migraine symptoms. Availability Midrin was discontinued by Caraco Pharmaceuticals as of 2009, after an FDA seizure of 33 drugs manufactured by Caraco Pharmaceuticals due to cGMP (Current Good Manufacturing Practices) violations. Generic forms of Amidrine were also discontinued due to loss of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isometheptene
Isometheptene (usually as isometheptene mucate) is a sympathomimetic amine sometimes used in the treatment of migraines and tension headaches due to its vasoconstricting properties; that is, it causes constriction (narrowing) of blood vessels (arteries and veins). Along with paracetamol and dichloralphenazone, it is one of the constituents of Amidrine. Chemistry Isometheptene is a monounsaturated aliphatic secondary amine. Mechanism of action Isometheptene's vasoconstricting properties arise through activation of the sympathetic nervous system via epinephrine and norepinephrine. These compounds elicit smooth muscle activation leading to vasoconstriction by interacting with cell surface adrenergic receptors. See also * Heptaminol * Methylhexanamine * Tuaminoheptane Tuaminoheptane (, ; brand names Heptin, Heptadrine, Tuamine; also known as tuamine and 2-aminoheptane) is a sympathomimetic agent and vasoconstrictor which was formerly used as a nasal decongestant.

Analgesic
An analgesic drug, also called simply an analgesic (American English), analgaesic (British English), pain reliever, or painkiller, is any member of the group of drugs used to achieve relief from pain (that is, analgesia or pain management). It is typically used to induce cooperation with a medical procedure. Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and anesthetic effects. Analgesic choice is also determined by the type of pain: For neuropathic pain, traditional analgesics are less effective, and there is often benefit from classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants. Various analgesics, such as many NSAIDs, are available over the counter in most countries, whereas various others are prescription drugs owing ...

Sedative
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 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antipyrine
Phenazone (INN and BAN; also known as phenazon, antipyrine (USAN), or analgesine) is an analgesic (pain reducing), antipyretic (fever reducing) and anti-inflammatory drug. While it predates the term, it is often classified as a nonsteroidal anti-inflammatory drug (NSAID). Phenazone was one of the earliest synthetic medications — when it was patented in 1883, the only synthetic medical chemicals on the market were chloral hydrate, a sedative (as well as at least one derivative of that chemical), trimethylamine, and iodol (tetraiodopyrrol), an early antiseptic. One of the earliest widely used analgesics and antipyretics, phenazone was gradually replaced in common use by other medications including phenacetin (itself later withdrawn because of safety concerns), aspirin, paracetamol and modern NSAIDs such as ibuprofen. However, it is still available in several countries either as an over-the-counter or prescribed drug. History Ludwig Knorr was the first to synthesize phenazone, th ...

Chloral Hydrate
Chloral hydrate is a geminal diol with the formula . It is a colorless solid. It has limited use as a sedative and hypnotic pharmaceutical drug. It is also a useful laboratory chemical reagent and precursor. It is derived from chloral (trichloroacetaldehyde) by the addition of one equivalent of water. History Chloral hydrate was discovered in 1832 by Justus von Liebig in Gießen when a chlorination ( halogenation) reaction was performed on ethanol. Its sedative properties were observed by Rudolf Buchheim in 1861, but described in detail and published only in 1869 by Oscar Liebreich; subsequently, because of its easy synthesis, its use became widespread. It was widely used for sedation in asylums and in general medical practice, and also became a popular drug of abuse in the late 19th century. One recreational user was the poet and illustrator Dante Gabriel Rossetti. Chloral hydrate is soluble in both water and ethanol, readily forming concentrated solutions. A solution of c ...

Paracetamol
Paracetamol, also known as acetaminophen, is a medication used to treat fever and mild to moderate pain. Common brand names include Tylenol and Panadol. At a standard dose, paracetamol only slightly decreases body temperature; it is inferior to ibuprofen in that respect, and the benefits of its use for fever are unclear. Paracetamol may relieve pain in acute mild migraine but only slightly in episodic tension headache. However, the aspirin/paracetamol/caffeine combination helps with both conditions where the pain is mild and is recommended as a first-line treatment for them. Paracetamol is effective for post-surgical pain, but it is inferior to ibuprofen. The paracetamol/ibuprofen combination provides further increase in potency and is superior to either drug alone. The pain relief paracetamol provides in osteoarthritis is small and clinically insignificant. The evidence in its favor for the use in low back pain, cancer pain, and neuropathic pain is insufficient. In the sho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insomnia
Insomnia, also known as sleeplessness, is a sleep disorder in which people have trouble sleeping. They may have difficulty falling asleep, or staying asleep as long as desired. Insomnia is typically followed by daytime sleepiness, low energy, irritability, and a depressed mood. It may result in an increased risk of motor vehicle collisions, as well as problems focusing and learning. Insomnia can be short term, lasting for days or weeks, or long term, lasting more than a month. The concept of the word insomnia has two possibilities: insomnia disorder and insomnia symptoms, and many abstracts of randomized controlled trials and systematic reviews often underreport on which of these two possibilities the word insomnia refers to. Insomnia can occur independently or as a result of another problem. Conditions that can result in insomnia include psychological stress, chronic pain, heart failure, hyperthyroidism, heartburn, restless leg syndrome, menopause, certain medications, and d ...

Chloral Betaine
Chloral betaine (USAN, BAN) (brand names Beta-Chlor, Somilan), also known as cloral betaine (INN), is a sedative- hypnotic drug. It was introduced by Mead Johnson in the United States in 1963. It is a betaine complex with chloral hydrate, which acts as an extended-acting formulation of chloral hydrate which is then metabolized into trichloroethanol, which is responsible for most or all of its effects. See also * Dichloralphenazone Dichloralphenazone is a 1:2 mixture of antipyrine with chloral hydrate.

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''.
