Expectorant
Mucoactive agents are a class of pharmacologic agents that include expectorants, mucolytics, mucoregulators, and mucokinetics that can affect the volume, viscosity, transportation, and composition of mucus or sputum. They often aid in clearing mucus or sputum from the upper and lower airways. These medications are used to treat respiratory diseases complicated by the oversecretion or inspissation of mucus. These drugs can be further categorized by their mechanism of action. Mechanism of action Mucoactive agents—expectorants—include mucolytics, secretolytics and mucokinetics (also called secretomotorics) * Mucolytics: thin (reduce the viscosity of) mucus * Secretolytics: increase airway water or the volume of airway secretions * Mucokinetics: increase mucociliary transport (clearance) and transportability of mucus by cough * Mucoregulators: suppress underlying mechanisms of mucus hypersecretion Alternatively, attacking the affinity between secretions and the biological ...

Guaifenesin
Guaifenesin, also known as glyceryl guaiacolate, sold under the brand name Mucinex, among others, is an expectorant medication taken by mouth and marketed as an aid to eliminate sputum from the respiratory tract. Chemically, it is an ether of guaiacol and glycerine. It may be used in combination with other medications. A 2014 study found that guaifenesin does not affect sputum volume in upper respiratory infections (the upper respiratory system includes most breathing parts ''above'' the lungs). It has been alleged to work in 2023 by making airway secretions more liquid. Side effects may include dizziness, sleepiness, skin rash, and nausea. While it has not been properly studied in pregnancy, it appears to be safe. Guaifenesin has been used medically since at least 1933. It is available as a generic medication and over-the-counter (OTC). In 2022, it was the 295th most commonly prescribed medication in the United States, with more than 400,000 prescriptions. In 2022, the com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cough Medicine
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. Types There are a number of different cough and cold medications, which may be used for various coughing symptoms. The commercially available products may include various combinations of any one or more of the following types of substances: * Mucokinetics, or mucolytics, are a class of drugs which ...

Terpin
Terpin is an expectorant, used to loosen mucus in patients with bronchitis and related conditions. It is used as the hydrate (terpin·H2O). It is derived from sources such as turpentine, oregano, thyme, and eucalyptus. It was used in the United States in the late nineteenth century, but was removed from marketed medications in the 1990s after the Food and Drug Administration (FDA) found a lack of evidence of safety and effectiveness.United States Food and Drug AdministrationCode of Federal Regulations, Title 21, Volume 5, April 1, 2009/ref> Elixirs of terpin hydrate are still available with a prescription, but must be prepared by a compounding pharmacy. It can be prepared from other volatile oils like geraniol and linalool by adding dilute acids (5% sulfuric acid) to them. Medical uses Terpin hydrate is an expectorant, used in the treatment of acute and chronic bronchitis, pneumonia, bronchiectasis, chronic obstructive pulmonary disease, and infectious and inflammatory disease ...

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 The lungs are the primary organs of the respiratory system in many animals, including humans. In mammals and most other tetrapods, two lungs are located near the backbone on either side of the heart. Their function in the respiratory syste .... For this re ...

Ambroxol
Ambroxol is a drug that breaks up phlegm, used in the treatment of respiratory diseases associated with viscid or excessive mucus. Ambroxol is often administered as an active ingredient in cough syrup. It was patented in 1966 and came into medical use in 1979. Medical uses Ambroxol is indicated as "secretolytic therapy in bronchopulmonary diseases associated with abnormal mucus secretion and impaired mucus transport. It promotes mucus clearance, facilitates expectoration and eases productive cough, allowing patients to breathe freely and deeply". There are many different formulations developed since the first marketing authorisation in 1978. Ambroxol is available as syrup, tablets, pastilles, dry powder sachets, inhalation solution, drops and ampules as well as effervescent tablets. Ambroxol also provides pain relief in acute sore throat. Pain in sore throat is the hallmark of acute pharyngitis. Sore throat is usually caused by a viral infection. The infection is se ...

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 .

Deoxyribonuclease
Deoxyribonuclease (DNase, for short) refers to a group of glycoprotein endonucleases which are enzymes that catalyze the hydrolytic cleavage of phosphodiester linkages in the DNA backbone, thus degrading DNA. The role of the DNase enzyme in cells includes breaking down extracellular DNA (ecDNA) excreted by apoptosis, necrosis, and neutrophil extracellular traps (NET) of cells to help reduce inflammatory responses that otherwise are elicited. A wide variety of deoxyribonucleases are known and fall into one of two families ( DNase I or DNase II), which differ in their substrate specificities, chemical mechanisms, and biological functions. Laboratory applications of DNase include purifying proteins when extracted from prokaryotic organisms. Additionally, DNase has been applied as a treatment for diseases that are caused by ecDNA in the blood plasma. Assays of DNase are emerging in the research field as well. Types The two main types of DNase found in animals are known as deoxy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
