Phenacetin
Phenacetin (acetophenetidin, ''N''-(4-ethoxyphenyl)acetamide) is a pain-relieving and fever-reducing drug, which was widely used following its introduction in 1887. It was withdrawn from medicinal use as dangerous from the 1970s (e.g., withdrawn in Canada in 1973, and by the U.S. Food and Drug Administration in 1983). History Phenacetin was introduced in 1887 in Elberfeld, Germany by German company Bayer, and was used principally as an analgesic; it was one of the first synthetic fever reducers to go on the market. It is also known historically to be one of the first non- opioid analgesics without anti-inflammatory properties. Although paracetamol was produced earlier, a historical accident saw it ignored after Joseph von Mering's assessment. Prior to World War One, Britain imported phenacetin from Germany. During the war, a team including Jocelyn Field Thorpe and Martha Annie Whiteley developed a synthesis in Britain. Known mechanism of action Phenacetin's analgesic effects a ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compound Analgesic
Compound analgesics are those with multiple active ingredients; they include many of the stronger prescription analgesics. Active ingredients that have been commonly used in compound analgesics include: * aspirin or ibuprofen * caffeine * codeine or oxycodone * paracetamol (acetaminophen) * phenacetin There is evidence that a compound of two analgesics with different mechanism of action can have an increased painkilling effect over the sum of the effect of each individual analgesic. Several such formulations have disappeared from over-the-counter status in drug store aisles and other retail outlets. One example is APC (aspirin, phenacetin, and caffeine) compound tablets common from the 1940s to 1983; because of harmful side effects of phenacetin, Anacin in the U.S. was reformulated to eliminate it; while Vincent's APC is no longer sold. Some others have been judged to contribute too often to substance abuse. Another example is Bex, a once popular Australian compound analgesic ...

Saridon
Propyphenazone/paracetamol/caffeine (trade name Saridon) is an analgesic combination indicated for the management of headache. It contains the analgesics propyphenazone and paracetamol and the stimulant caffeine. Saridon was first launched by Roche in 1933, initially containing pyrithyldione and phenacetin, widely used remedies for fever and pain. It often contained aspirin, phenacetin and caffeine, but was reformulated in 1981, replacing the original ingredient phenacetin with paracetamol, before phenacetin was banned by the US FDA in 1983. It was available in more than 80 countries across Europe, Latin America, Asia and Africa, but has been discontinued in many of them. Medical uses This combination is used for the relief of pain such as headache, toothache, menstrual discomfort, pain and fever associated with colds and flu, and for postoperative and rheumatic pain. Efficacy Paracetamol, an analgesic and antipyretic substance, has slow onset but has a longer duration of acti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
P-Phenetidine
''p''-Phenetidine (4-ethoxyaniline) is a chemical compound with the molecular formula C8H11NO. It is one of the three isomers of phenetidine. It is used as an intermediate in the synthesis of pharmaceutical drugs, dyes, and the sweetener dulcin. ''p''-Phenetidine is a metabolite of the pharmaceutical drugs bucetin and phenacetin and of the preservative ethoxyquin. It is also used as a chemical intermediate in the manufacture of bucetin, phenacetin, and ethoxyquin. ''p''-Phenetidine has high renal toxicity and it is believed to be responsible for the adverse effects that led to the withdrawal of phenacetin and bucetin from pharmaceutical use. ''p''-Phenetidine is also a possible mutagen. It is used in the synthesis of Phenacaine Phenacaine, also known as holocaine, is a local anesthetic. It is approved for ophthalmic use. Synthesis The condensation of P-Phenetidine (1) with triethyl orthoacetate Triethyl orthoacetate is the organic compound with the formula CH3C(OC2H .. ...

Vincent's APC
Vincent Chemical Company was an Australian business noted for manufacture of a popular compound analgesic "Vincent's APC" History Dr. Harry John Clayton (ca.1887 – 31 October 1928) of Macquarie Street and medical superintendent of the Royal Prince Alfred Hospital, Sydney, took the headache remedy then in general use, composed of phenacetin and caffeine, and by experimenting with the addition of aspirin, arrived at what became the standard formulation known as A.P.C. powder, or in the Royal Prince Alfred Hospital Pharmacopæia for 1918 as ''Pulvis Analgesicus''. In 1919, at the insistence of his wife, Clayton founded a partnership consisting of Mrs Clayton, E. W. Wills, C. K. Probert (dispenser at the Royal Prince Alfred Hospital), and J. A. Vincent (1890 – 12 June 1933), who had been assistant dispenser at the hospital, and was at that time a pharmacist with a business at Five Dock. Clayton chose the names "Vincent Chemical Company" and "Vincent's APC" to distance himself, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antipyretic
An antipyretic (, from ''anti-'' 'against' and ' 'feverish') is a substance that reduces fever. Antipyretics cause the hypothalamus to override a prostaglandin-induced increase in temperature. The body then works to lower the temperature, which results in a reduction in fever. Most antipyretic medications have other purposes. The most common antipyretics in the US are usually ibuprofen and aspirin, which are nonsteroidal anti-inflammatory drugs (NSAIDs) used primarily as anti-inflammatories and analgesics (pain relievers), but which also have antipyretic properties; and paracetamol (acetaminophen), an analgesic without anti-inflammatory properties. There is some debate over the appropriate use of such medications, since fever is part of the body's immune response to infection. A study published by the Royal Society claims that fever suppression causes at least 1% more influenza deaths in the United States, or 700 extra deaths per year.

Aspirin
Aspirin, also known as acetylsalicylic acid (ASA), is a nonsteroidal anti-inflammatory drug (NSAID) used to reduce pain, fever, and/or inflammation, and as an antithrombotic. Specific inflammatory conditions which aspirin is used to treat include Kawasaki disease, pericarditis, and rheumatic fever. Aspirin is also used long-term to help prevent further heart attacks, ischaemic strokes, and thrombus, blood clots in people at high risk. For pain or fever, effects typically begin within 30 minutes. Aspirin works similarly to other NSAIDs but also suppresses the normal functioning of platelets. One common adverse effect is an upset stomach. More significant side effects include stomach ulcers, stomach bleeding, and worsening asthma. Bleeding risk is greater among those who are older, drink Alcohol (drug), alcohol, take other NSAIDs, or are on other anticoagulant, blood thinners. Aspirin is not recommended in the last part of pregnancy. It is not generally recommended in children ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caffeine
Caffeine is a central nervous system (CNS) stimulant of the methylxanthine chemical classification, class. It is mainly recreational drug use, used recreationally as a Nootropic, cognitive enhancer, increasing alertness and attentional performance. Caffeine acts by blocking binding of adenosine to the adenosine A1 receptor, which enhances release of the neurotransmitter acetylcholine. Caffeine has a three-dimensional structure similar to that of adenosine, which allows it to bind and block its receptors. Caffeine also increases Cyclic adenosine monophosphate, cyclic AMP levels through nonselective inhibition of phosphodiesterase. Caffeine is a bitter, white crystalline purine, a methylxanthine alkaloid, and is chemically related to the adenine and guanine nucleobase, bases of DNA, deoxyribonucleic acid (DNA) and RNA, ribonucleic acid (RNA). It is found in the seeds, fruits, nuts, or leaves of a number of plants native to Africa, East Asia and South America, and helps to prote ...

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 owi ...

California State University Stanislaus
California State University, Stanislaus (Stanislaus State, Stan State) is a public university in Turlock, Stanislaus County, California. It is part of the California State University system. It was established in 1957 and is also the only campus in the system to offer a bachelor's degree in cognitive studies. The university offers 45 Bachelor's degrees, 17 Master's degrees, one Doctoral degree (Doctor of Education), and 6 teaching credentials. Stanislaus State is a Hispanic-serving institution. History In 1957, the California State Legislature established what was then called Stanislaus State College as the 15th campus of the CSU system. Because Turlock was better known at the time for its turkeys than its aspirations towards higher education, Clark Kerr highlighted this event in his memoirs as an example of how the state colleges had become vulnerable to pork barrel politics in the state legislature. This was one of several reasons behind the creation of the California Master ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
