Antitussive
Cold medicines are a group of medications taken individually or in combination as a treatment for the symptoms of the common cold and similar conditions of the upper respiratory tract. The term encompasses a broad array of drugs, including analgesics, antihistamines and decongestants, among many others. It also includes drugs which are marketed as cough suppressants or antitussives, but their effectiveness in reducing cough symptoms is unclear or minimal. While they have been used by 10% of American children in any given week, they are not recommended in Canada or the United States in children six years or younger because of lack of evidence showing effect and concerns of harm. In 2020, one version containing codeine and guaifenesin was the 377th most commonly prescribed medication in the United States with more than 400thousand prescriptions. Types There are a number of different cough and cold medications, which may be used for various coughing symptoms. The commercially a ...

Noscapine
Noscapine (also known as Narcotine, Nectodon, Nospen, Anarcotine and (archaic) Opiane) is a benzylisoquinoline alkaloid, of the phthalideisoquinoline structural subgroup, which has been isolated from numerous species of the family Papaveraceae (poppy family). It lacks significant hypnotic, euphoric, or analgesic effects affording it with very low addictive potential. This agent is primarily used for its antitussive (cough-suppressing) effects. Medical uses Noscapine is often used as an antitussive medication. A 2012 Dutch guideline, however, does not recommend its use for acute coughing. Side effects *Nausea *Vomiting *Loss of coordination *Hallucinations (auditory and visual) * Loss of sexual drive * Swelling of prostate *Loss of appetite *Dilated pupils *Increased heart rate * Shaking and muscle spasms *Chest pains *Increased alertness *Loss of any sleepiness *Loss of stereoscopic vision Interactions Noscapine can increase the effects of centrally sedating substances such as ...

Dextromethorphan
Dextromethorphan (DXM) is a medication most often used as a cough suppressant in over-the-counter cold and cough medicines. It is sold in syrup, tablet, spray, and lozenge forms. In 2022, the FDA approved a formulation of it combined with bupropion named Auvelity to serve as a rapid acting antidepressant in patients with major depressive disorder. It is in the morphinan class of medications with sedative, dissociative, and stimulant properties (at lower doses). Dextromethorphan does not have a significant affinity for the mu-opioid receptor activity typical of morphinan compounds and exerts its therapeutic effects through several other receptors. In its pure form, dextromethorphan occurs as a white powder. Dextromethorphan is also used recreationally. When exceeding approved dosages, dextromethorphan acts as a dissociative hallucinogen. It has multiple mechanisms of action, including actions as a nonselective serotonin reuptake inhibitor and a sigma-1 receptor agonis ...

Pholcodine
Pholcodine is an opioid cough suppressant (antitussive). It helps suppress unproductive coughs and also has a mild sedative effect, but has little or no analgesic effects. It is also known as morpholinylethylmorphine and homocodeine. Pholcodine is found in certain cough lozenges, and more commonly as an oral solution, typically 5 mg / 5 ml. Adult dosage is 5-10 ml up to 3-4 times daily. Pholcodine now largely replaces the previously more common codeine linctus, as it has a much lower potential for dependence. Pholcodine is used as an antitussive agent in Australia, Belgium, Finland, France, Ireland, New Zealand, Norway, and the U It is a Drugs controlled by the UK Misuse of Drugs Act#Class B drugs, class B substance in the United Kingdom but can be purchased over-the-counter in most UK pharmacies. Pholcodine is not prescribed in the United States where it is classed as a Schedule I drug, the most highly controlled drug category, which includes the likes of heroin, LSD an ...

Guaifenesin
Guaifenesin, also known as glyceryl guaiacolate, is an expectorant medication that aids in the elimination of sputum from the respiratory tract. Chemically it is an ether of guaiacol and glycerine. It is often used in combination with other medications. It is taken by mouth. Side effects may include dizziness, sleepiness, skin rash, and nausea. While it has not been properly studied in pregnancy, it appears to be safe. It is believed to work by making airway secretions more liquid. Guaifenesin has been used medically since at least 1933. It is available as a generic medication and over the counter. In 2020, it was the 324th most commonly prescribed medication in the United States, with more than 800,000 prescriptions. Medical use Guaifenesin is used to try to help with coughing up thick mucus and is sometimes combined with dextromethorphan, an antitussive (cough suppressant), such as in Mucinex DM or Robitussin DM. It is also combined with ephedrine to produce Primatene and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bromhexine
Bromhexine is a mucolytic drug used in the treatment of respiratory system, respiratory disorders associated with viscid or excessive mucus. It was developed in the research laboratory of Boehringer Ingelheim in the late 1950s as an active ingredient for pharmaceutical use, Patent, patented in 1961, introduced in 1963 under the trademark of Bisolvon® and came into medical use in 1966. Function Bromhexine is intended to support the body's mechanisms for clearing mucus from the respiratory tract. It is secretolytic, increasing the production of serous mucus in the respiratory tract, which makes the phlegm thinner and less viscous. This contributes to a secretomotoric effect, allowing the cilia to more easily transport the phlegm out of the lungs. For this reason it is often added to antitussive, cough syrups. It has been shown to increase the proportion of serous bronchial secretion, making it more easily expectorant, expectorated. It is indicated as "secretolytic therapy in bron ...

Carbocisteine
Carbocisteine, also called carbocysteine, is a mucolytic that reduces the viscosity of sputum and so can be used to help relieve the symptoms of chronic obstructive pulmonary disorder (COPD) and bronchiectasis by allowing the sufferer to bring up sputum more easily. Carbocisteine should not be used with antitussives (cough suppressants) or medicines that dry up bronchial secretions. It was first described in 1951 and came into medical use in 1960. Carbocisteine is produced by alkylation of cysteine with chloroacetic acid Chloroacetic acid, industrially known as monochloroacetic acid (MCA), is the organochlorine compound with the formula ClCH2CO2H. This carboxylic acid is a useful building block in organic synthesis. It is a colorless solid. Related compounds ....

Butamirate
Butamirate (or brospamin, trade names Acodeen, Codesin, Pertix, Sinecod, Sinecoden, Sinecodix) is a cough suppressant. It has been marketed in Europe and Mexico, but not in the United States. As the citrate salt, it is sold in the form of lozenges, syrup, tablets, dragées, or pastilles. Adverse effects can include nausea, diarrhea, vertigo, and exanthema. Pharmacology A study found it to bind to the cough center in the medulla oblongata, more specifically the dextromethorphan-binding site in guinea pig brain with high affinity. As a 2-(2-diethylaminoethoxy)ethyl ester, it is chemically related to oxeladin and pentoxyverine, which are in the same class. (Oxeladin has an additional ethyl group in its carboxylic acid, pentoxyverine has both ethyl groups of oxeladin replaced by one cyclopentyl in the same place.)

Pseudoephedrine
Pseudoephedrine (PSE) is a sympathomimetic drug of the phenethylamine and amphetamine chemical classes. It may be used as a nasal/sinus decongestant, as a stimulant, or as a wakefulness-promoting agent in higher doses. It was first characterized in 1889 by the German chemists Ladenburg and Oelschlägel, who used a sample that had been isolated from ''Ephedra vulgaris'' by the Merck pharmaceutical corporation of Darmstadt, Germany. The salts pseudoephedrine hydrochloride and pseudoephedrine sulfate are found in many over-the-counter preparations, either as a single ingredient or (more commonly) in a fixed-dose combination with one or more additional active ingredients such as antihistamines, guaifenesin, dextromethorphan, paracetamol (acetaminophen) or an NSAID (such as aspirin or ibuprofen). Medical uses Pseudoephedrine is a stimulant, but it is well known for shrinking swollen nasal mucous membranes, so it is often used as a decongestant. It reduces tissue hyperemia, ede ...

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 or adults. In Europe, it is not recommended as a cough medicine in 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. Common side effects include vomiting, constipation, itchiness, lightheadedness, and drowsiness. Serious side effects may include breathing difficult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cetirizine
Cetirizine, sold under the brand name Zyrtec among others, is a second-generation antihistamine used to treat allergic rhinitis (hay fever), dermatitis, and urticaria (hives). It is taken by mouth. Effects generally begin within thirty minutes and last for about a day. The degree of benefit is similar to other antihistamines such as diphenhydramine. Common side effects include sleepiness, dry mouth, headache, and abdominal pain. The degree of sleepiness that occurs is generally less than with first generation antihistamines. Use in pregnancy appears safe, but use during breastfeeding is not recommended. The medication works by blocking histamine H1 receptors, mostly outside the brain. It was patented in 1981 and came into medical use in 1987. It is on the World Health Organization's List of Essential Medicines. It is available as a generic medication. In 2020, it was the 52nd most commonly prescribed medication in the United States, with more than 13million prescriptions. ...

Flu-like Syndrome
Influenza-like illness (ILI), also known as flu-like syndrome or flu-like symptoms, is a medical diagnosis of possible influenza or other illness causing a set of common symptoms. These include fever, shivering, chills, malaise, dry cough, loss of appetite, body aches, and nausea, sneezing typically in connection with a sudden onset of illness. In most cases, the symptoms are caused by cytokines released by immune system activation, and are thus relatively non-specific. Common causes of ILI include the common cold and influenza, which tends to be less common but more severe than the common cold. Less common causes include side effects of many drugs and manifestations of many other diseases. Definition The term ILI can be used casually, but when used in the surveillance of influenza cases, can have a strict definition. The World Health Organization defines an illness as an ILI if the patient has a fever greater than or equal to 38 C° and a cough, which began in the last 10 days. ...

Decongestant
A decongestant, or nasal decongestant, is a type of pharmaceutical drug that is used to relieve nasal congestion in the upper respiratory tract. The active ingredient in most decongestants is either pseudoephedrine or phenylephrine (the latter of which has disputed effectiveness). Intranasal corticosteroids can also be used as decongestants and antihistamines can be used to alleviate runny nose, nasal itch, and sneezing. Topical decongestants on topical application as dilute solution (0.05–0.1%) produce local vasoconstriction. Regular use of decongestants for long periods should be avoided because mucosal ciliary function is impaired: atrophic rhinitis and anosmia (loss of the sense of smell) can occur due to persistent vasoconstriction. Decongestants can be absorbed from the nose via an inhaler and produce systemic effects, mainly central nervous system stimulation and rise in blood pressure. These drugs should be used cautiously in hypertensives and in those receiving mono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
