Mucolytic
Mucoactive agents are a class of chemical agents that aid in the clearance of mucus or sputum from the upper and lower airways, including the lungs, bronchi, and trachea. Mucoactive drugs include expectorants, mucolytics, mucoregulators, and mucokinetics. These medications are used in the treatment of respiratory diseases that are 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 surface ...

Acetylcysteine
Acetylcysteine, also known as ''N''-acetylcysteine (NAC), is a medication that is used to treat paracetamol overdose and to loosen thick mucus in individuals with chronic bronchopulmonary disorders like pneumonia and bronchitis. It has been used to treat lactobezoar in infants. It can be taken intravenously, by mouth, or inhaled as a mist. Some people use it as a dietary supplement. Common side effects include nausea and vomiting when taken by mouth. The skin may occasionally become red and itchy with any route of administration. A non-immune type of anaphylaxis may also occur. It appears to be safe in pregnancy. For paracetamol overdose, it works by increasing the level of glutathione, an antioxidant that can neutralise the toxic breakdown products of paracetamol. When inhaled, it acts as a mucolytic by decreasing the thickness of mucus. Acetylcysteine was initially patented in 1960 and came into medical use in 1968. It is on the World Health Organization's List of Ess ... [...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 The lungs are the primary organs of the respiratory system in humans and most other animals, including some snails and a small number of fish. In mammals and most other vertebrates, two lungs are located near the backbone on either si .... For this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mucoprotein
A mucoprotein is a glycoprotein composed primarily of mucopolysaccharides. Mucoproteins can be found throughout the body, including the gastrointestinal tract, reproductive organs, airways, and the synovial fluid of the knees. They are called mucoproteins because the carbohydrate quantity is more than 4% unlike glycoproteins where the carbohydrate quantity is less than 4%. Mucoprotein is produced in the cecum of the gastrointestinal tract. During gallbladder cancer, mucoprotein is over expressed. Sustaining a brain injury will lead to decreased mucoprotein production. The result is an alteration of gut microbiota as seen in mice. Function Mucoproteins are the proteins that are the building blocks of mucus, which is a protective barrier to the epithelia of cells. It is semipermeable, so it acts as a barrier to most bacteria and pathogens, while allowing for the uptake of nutrients, water Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and ...

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 a ....

Mucus
Mucus ( ) is a slippery aqueous secretion produced by, and covering, mucous membranes. It is typically produced from cells found in mucous glands, although it may also originate from mixed glands, which contain both serous and mucous cells. It is a viscous colloid containing inorganic salts, antimicrobial enzymes (such as lysozymes), immunoglobulins (especially IgA), and glycoproteins such as lactoferrin and mucins, which are produced by goblet cells in the mucous membranes and submucosal glands. Mucus serves to protect epithelial cells in the linings of the respiratory, digestive, and urogenital systems, and structures in the visual and auditory systems from pathogenic fungi, bacteria and viruses. Most of the mucus in the body is produced in the gastrointestinal tract. Amphibians, fish, snails, slugs, and some other invertebrates also produce external mucus from their epidermis as protection against pathogens, and to help in movement and is also produced in fish ...

Dornase Alfa
Dornase alfa (proprietary name Pulmozyme from Genentech) is a highly purified solution of recombinant human deoxyribonuclease I (rhDNase), an enzyme which selectively cleaves DNA. Dornase alfa hydrolyzes the DNA present in sputum/mucus of cystic fibrosis patients and reduces viscosity in the lungs, promoting improved clearance of secretions. This protein therapeutic agent is produced in Chinese hamster ovary cells. Cystic fibrosis Dornase alfa is the most recent therapeutic agent developed with this basic mechanism of action. Prior to the cloning of the human enzyme, bovine DNase I was on the market for many years, though its utility was limited by the inherent antigenic response to a cow protein in the lungs of patients. Other DNases, such as DNase II, have therapeutic potential as well, but no further DNases have been brought to market yet for cystic fibrosis. Dornase alfa is an orphan drug.
