Thebacon
Thebacon (INN; pronounced ), or dihydrocodeinone enol acetate, is a semisynthetic opioid that is similar to hydrocodone and is most commonly synthesised from thebaine. Thebacon was invented in Germany in 1924, four years after the first synthesis of hydrocodone. Thebacon is a derivative of acetyldihydrocodeine, where only the 6–7 double bond is saturated. Thebacon is marketed as its hydrochloride salt under the trade name Acedicon, and as its bitartrate under Diacodin and other trade names. The hydrochloride salt has a free base conversion ratio of 0.846. Other salts used in research and other settings include thebacon's phosphate, hydrobromide, citrate, hydroiodide, and sulfate. Medical uses Thebacon is an opioid agonist narcotic analgesic of the middle range and a strong antitussive, primarily used in Europe, although it is no longer in common use. Currently, dihydrocodeine and nicocodeine are used as second-line codeine replacements. The other dihydromorphinone u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acetyldihydrocodeine
Acetyldihydrocodeine is an opiate derivative discovered in Germany in 1914 and was used as a cough suppressant and analgesic. It is not commonly used, but has activity similar to other opiates. Acetyldihydrocodeine is a very close relative derivative of thebacon, where only the 6-7 bond is unsaturated. Acetyldihydrocodeine can be described as the 6-acetyl derivative of dihydrocodeine and is metabolised in the liver by demethylation and deacetylation to produce dihydromorphine. Since acetyldihydrocodeine has higher lipophilicity than codeine and is converted into dihydromorphine rather than morphine, it can be expected to be more potent and longer-lasting. It also has a higher bioavailability than codeine. Side effects are similar to those of other opiates and include itching, nausea and respiratory depression Hypoventilation (also known as respiratory depression) occurs when ventilation is inadequate (''hypo'' meaning "below") to perform needed respiratory gas exchange.

Hydrocodone
Hydrocodone, also known as dihydrocodeinone, is a semi-synthetic opioid used to treat pain and as a cough suppressant. It is taken by mouth. Typically, it is dispensed as the combination acetaminophen/hydrocodone or ibuprofen/hydrocodone for pain severe enough to require an opioid and in combination with homatropine methylbromide to relieve cough. It is also available by itself in a long-acting form sold under the brand name Zohydro ER, among others, to treat severe pain of a prolonged duration. Hydrocodone is a controlled drug: in the United States, it is classified as a Schedule II Controlled Substance. Common side effects include dizziness, sleepiness, nausea, and constipation. Serious side effects may include low blood pressure, seizures, QT prolongation, respiratory depression, and serotonin syndrome. Rapidly decreasing the dose may result in opioid withdrawal. Use during pregnancy or breastfeeding is generally not recommended. Hydrocodone is believed to work ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Codeine
Codeine is an opiate and prodrug of morphine mainly used to treat pain, coughing, and diarrhea. It is also commonly used as a recreational drug. It is found naturally in the sap of the opium poppy, ''Papaver somniferum''. It is typically used to treat mild to moderate degrees of pain. Greater benefit may occur when combined with paracetamol (acetaminophen) or a nonsteroidal anti-inflammatory drug (NSAID) such as aspirin or ibuprofen. Evidence does not support its use for acute cough suppression in children. In Europe, it is not recommended as a cough medicine for those under 12 years of age. It is generally taken by mouth. It typically starts working after half an hour, with maximum effect at two hours. Its effects last for about four to six hours. Codeine exhibits abuse potential similar to other opioid medications, including a risk of addiction and overdose. Common side effects include nausea, vomiting, constipation, itchiness, lightheadedness, and drowsiness. Serious ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diário Oficial Da União
The ''Diário Oficial da União'' (literally ''Official Diary of the Union''), abbreviated DOU, is the government gazette, official gazette of the Federal Government of Brazil, Federal Government of Brazil. It is published since 1 October 1862 and was created via the Imperial Decree 1,177 of its 9 September as the ''Official Journal of the Empire of Brazil''. Its current name was adopted after Brazil became a federal republic, and the "Union" came into being as the legal personality of the new federal government. The official journal is published by the Imprensa Nacional, Brazilian National Press. Though the journal has been published since 1862, it had many predecessors, as follows: # Gazeta do Rio de Janeiro (10/9/1808 – 29.12.1821) # Gazeta do Rio (1/1/1822 – 31/12/1822) # Diário do Governo (2/1/1823 – 28/6/1833) # Diário Fluminense (21/5/1824 – 24/4/1831) # Correio Oficial (1/7/1833 – 30/6/1836) e (2/1/1830 – 30/12/1840) # Without proper journal (31/12/1840 – ...

Nicocodeine
Nicocodeine (Lyopect, Tusscodin) is an opioid analgesic and cough suppressant, an ester of codeine closely related to dihydrocodeine and the codeine analogue of nicomorphine. It is not commonly used in most countries, but has activity similar to other opiates. Nicocodeine and nicomorphine were synthesized in 1904, and introduced in 1957 by Lannacher Heilmittel of Austria. Nicocodeine is metabolised in the liver by demethylation to produce nicomorphine, also known as 6-nicotinoylmorphine, and subsequently further metabolised to morphine. Side effects are similar to those of other opiates and include itching, nausea and respiratory depression. Related opioid analogues such as nicomorphine and nicodicodeine were first synthesized. The definitive synthesis, which involves treating anhydrous codeine base with nicotinic anhydride at 130 °C, was published by Pongratz and Zirm in ''Monatshefte für Chemie'' in 1957, simultaneously with the two analogues in an article about ami ...

Chlorpheniramine
Chlorphenamine (CP, CPM), also known as chlorpheniramine, is an antihistamine used to treat the symptoms of allergic conditions such as allergic rhinitis (hay fever). It is taken orally (by mouth). The medication takes effect within two hours and lasts for about 4–6 hours. It is a first-generation antihistamine and works by blocking the histamine H1 receptor. Common side effects include sleepiness, restlessness, and weakness. Other side effects may include dry mouth and wheeziness. Chlorpheniramine was patented in 1948 and came into medical use in 1949. It is available as a generic medication and over the counter. In 2022, it was the 291st most commonly prescribed medication in the United States, with more than 400,000 prescriptions. Medical uses Combination products Chlorphenamine is often combined with phenylpropanolamine to form an allergy medication with both antihistamine and decongestant properties, although phenylpropanolamine was removed from the U.S. m ...

Phenyltoloxamine
Phenyltoloxamine is an antihistamine with sedative and analgesic effects. It is available in combination with other drugs such as paracetamol (acetominophen). Common use Phenyltoloxamine is widely used in preparations as an enhancing agent for some analgesics and antitussives (acetaminophen, dihydrocodeine, codeine, hydrocodone). It is widely used in certain parts of the world as cough suppressant usually with codeine, and sometimes by itself or in addition to dextromethorphan as it, like diphenhydramine, possesses antitussive action of its own and is particularly useful in semi-productive coughs because of its moderate drying action. Phenyltoloxamine is used in combination with paracetamol, aspirin and other salicylates and other drugs in proprietary preparations available over the counter for backache, muscle strains and similar conditions. Adverse effects Common adverse effects are those associated with most anticholinergics, with effects being more pronounced in childr ...

Promethazine
Promethazine, sold under the brand name Phenergan among others, is a first-generation antihistamine, sedative, and antiemetic used to treat allergies, insomnia, and nausea. It may also help with some symptoms associated with the common cold and may also be used for sedating people who are agitated or anxious, an effect that has led to some recreational use ( especially with codeine). Promethazine is taken by mouth (oral), as a rectal suppository, or by injection into a muscle (IM). Common side effects of promethazine include confusion and sleepiness; consumption of alcohol or other sedatives can make these symptoms worse. It is unclear if use of promethazine during pregnancy or breastfeeding is safe for the fetus. Use of promethazine is not recommended in those less than two years old, due to potentially negative effects on breathing. Use of promethazine by injection into a vein is not recommended, due to potential skin damage. Promethazine is in the phenothiazine family ...

Hydroxyzine
Hydroxyzine, sold under the brand names Atarax and Vistaril among others, is an antihistamine medication. It is used in the treatment of itchiness, anxiety, insomnia, and nausea (including that due to motion sickness). It is used either by mouth or injection into a muscle. Hydroxyzine works by blocking the effects of histamine. It is a first-generation antihistamine in the piperazine family of chemicals. Common side effects include sleepiness, headache, and dry mouth. Serious side effects may include QT prolongation. It is unclear if use during pregnancy or breastfeeding is safe. It was first made by Union Chimique Belge in 1956 and was approved for sale by Pfizer in the United States later that year. In 2022, it was the 46th most commonly prescribed medication in the United States, with more than 13million prescriptions. Medical uses Hydroxyzine is used in the treatment of itchiness, anxiety, and nausea due to motion sickness. A systematic review concluded that hydrox ...

Tripelennamine
Tripelennamine, sold under the brand name Pyribenzamine by Novartis, is a drug that is used as an antipruritic and first-generation antihistamine. It can be used in the treatment of asthma, hay fever, rhinitis, and urticaria, but is now less common as it has been replaced by newer antihistamines. The drug was patented at CIBA, which merged with Geigy into Ciba-Geigy, and eventually becoming Novartis. Medical uses Where and when it is/was in common use, tripelennamine is used much like other mildly-anticholinergic antihistamines to treat conditions of the upper respiratory tract arising from illnesses and hay fever. It can be used alone or in combination with other agents to have the desired effect. Cough medicines of the general formula tripelennamine + codeine/dihydrocodine/hydrocodone ± expectorant ± decongestant(s) are popular where available. Among these are the Pyribenzamine cough syrups which contain codeine, with and without decongestants, listed in the 1978 ''Physic ...

Antihistamines
Antihistamines are drugs which treat allergic rhinitis, common cold, influenza, and other allergies. Typically, people take antihistamines as an inexpensive, generic (not patented) drug that can be bought without a prescription and provides relief from nasal congestion, sneezing, or hives caused by pollen, dust mites, or animal allergy with few side effects. Antihistamines are usually for short-term treatment. Chronic allergies increase the risk of health problems which antihistamines might not treat, including asthma, sinusitis, and lower respiratory tract infection. Consultation of a medical professional is recommended for those who intend to take antihistamines for longer-term use. Although the general public typically uses the word "antihistamine" to describe drugs for treating allergies, physicians and scientists use the term to describe a class of drug that opposes the activity of histamine receptors in the body. In this sense of the word, antihistamines are subclas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muscle Relaxants
A muscle relaxant is a drug that affects skeletal muscle function and decreases the muscle tone. It may be used to alleviate symptoms such as muscle spasms, pain, and hyperreflexia. The term "muscle relaxant" is used to refer to two major therapeutic groups: Neuromuscular-blocking drugs, neuromuscular blockers and Antispasmodic, spasmolytics. Neuromuscular blockers act by interfering with transmission at the neuromuscular end plate and have no central nervous system (CNS) activity. They are often used during surgical procedures and in intensive care and emergency medicine to cause temporary paralysis. Spasmolytics, also known as "centrally acting" muscle relaxant, are used to alleviate musculoskeletal pain and spasms and to reduce spasticity in a variety of neurological conditions. While both neuromuscular blockers and spasmolytics are often grouped together as muscle relaxant, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
