Robitussin
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 commerci ...

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 ...

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] |
Bromhexine
Bromhexine is a mucolytic drug used in the treatment of 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, 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 cough syrups. It has been shown to increase the proportion of serous bronchial secretion, making it more easily expectorated. It is indicated as "secretolytic therapy in bronchopulmonary diseases associated with abnormal mucus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ephedrine
Ephedrine is a central nervous system (CNS) stimulant that is often used to prevent low blood pressure during anesthesia. It has also been used for asthma, narcolepsy, and obesity but is not the preferred treatment. It is of unclear benefit in nasal congestion. It can be taken by mouth or by injection into a muscle, vein, or just under the skin. Onset with intravenous use is fast, while injection into a muscle can take 20 minutes, and by mouth can take an hour for effect. When given by injection it lasts about an hour and when taken by mouth it can last up to four hours. Common side effects include trouble sleeping, anxiety, headache, hallucinations, high blood pressure, fast heart rate, loss of appetite, and inability to urinate. Serious side effects include stroke and heart attack. While likely safe in pregnancy, its use in this population is poorly studied. Use during breastfeeding is not recommended. Ephedrine works by increasing the activity of the α and β adrenergic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 receivin ... [...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. ...

Phenylephrine
Phenylephrine is a medication primarily used as a decongestant, to dilate the pupil, to increase blood pressure, and to relieve hemorrhoids. In the United States, it was previously used orally as an over-the-counter decongestant to relieve nasal congestion due to sinusitis, but this use was discontinued in 2007. As of 2022, its use as a nasal decongestant in other applications still persists. Phenylephrine can be taken by mouth, as a nasal spray, given by injection into a vein or muscle, or applied to the skin. Common side effects when taken by mouth or injected include nausea, vomiting, headache, and anxiety. Use on hemorrhoids is generally well tolerated. Severe side effects may include a slow heart rate, intestinal ischemia, chest pain, kidney failure, and tissue death at the site of injection. It is unclear if use during pregnancy or breastfeeding is safe. Phenylephrine is a selective α1-adrenergic receptor agonist which results in the constriction of both arteries a ...

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.)

Loratadine
Loratadine, sold under the brand name Claritin among others, is a medication used to treat allergies. This includes allergic rhinitis (hay fever) and hives. It is also available in combination with pseudoephedrine, a decongestant, known as loratadine/pseudoephedrine. It is taken orally. Common side effects include sleepiness, dry mouth, and headache. Serious side effects are rare and include allergic reactions, seizures, and liver problems. Use during pregnancy appears to be safe but has not been well studied. It is not recommended in children less than two years old. It is in the second-generation antihistamine family of medication. Loratadine was patented in 1980 and came to market in 1988. It is on the World Health Organization's List of Essential Medicines. Loratadine is available as a generic medication. In the United States, it is available over the counter.

Brompheniramine
Brompheniramine, sold under the brand name Dimetapp among others, is a first-generation antihistamine drug of the propylamine (alkylamine) class. It is indicated for the treatment of the symptoms of the common cold and allergic rhinitis, such as runny nose, itchy eyes, watery eyes, and sneezing. Like the other first-generation drugs of its class, it is considered a sedating antihistamine. It was patented in 1948 and came into medical use in 1955. Side effects Brompheniramine's effects on the cholinergic system may include side-effects such as drowsiness, sedation, dry mouth, dry throat, blurred vision, and increased heart rate. It is listed as one of the drugs of highest anticholinergic activity in a study of anticholinergenic burden, including long-term cognitive impairment. Pharmacology Brompheniramine works by acting as an antagonist of histamine H1 receptors. It also functions as a moderately effective anticholinergic agent, and is likely an antimuscarinic agent simil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 by mouth. The medication takes effect within two hours and lasts for about 4-6. Common side effects include sleepiness, restlessness, and weakness. Other side effects may include dry mouth and wheeziness. It is a first-generation antihistamine and works by blocking the H1 receptor. Chlorpheniramine was patented in 1948 and came into medical use in 1949. It is available as a generic medication and over the counter. Medical uses Combination products Chlorphenamine is often combined with phenylpropanolamine to form an allergy medication with both antihistamine and decongestant properties, though phenylpropanolamine is no longer available in the US after studies showed it increased the risk of stroke in young women. Chlorphenamine remains available with no such risk. Chlorphenamine may be combined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
