⚫ | '''Cromoglicic acid''' ([[International Nonproprietary Name|INN]])—also referred to as '''cromolyn''' ([[United States Adopted Name|USAN]]), '''cromoglycate''' (former [[British Approved Name|BAN]]), or '''cromoglicate'''—is traditionally described as a [[mast cell stabilizer]], and is commonly marketed as the sodium salt '''sodium cromoglicate''' or '''cromolyn sodium'''. This drug prevents the release of [[inflammation|inflammatory]] chemicals such as [[histamine]] from [[mast cell]]s. |

It is considered a breakthrough drug in management of asthma, as the patients can be freed from steroids in many cases; however, it is mainly effective as a prophylaxis for allergic and exercise-induced asthma, not as a treatment for acute asthma attacks.{{cn|date=March 2024}} |
|||
⚫ | Cromoglicic acid has been the non-[[corticosteroid]] treatment of choice in the treatment of [[asthma]], for which it has largely been replaced by [[leukotriene receptor antagonist]]s because of their safety and convenience. Cromoglicic acid requires administration four times daily, and does not provide additive benefit in combination with inhaled corticosteroids.<ref>{{cite journal | vauthors = Fanta CH | title = Asthma | journal = The New England Journal of Medicine | volume = 360 | issue = 10 | pages = 1002–1014 | date = March 2009 | pmid = 19264689 | doi = 10.1056/NEJMra0804579 }} Review.</ref> |

Cromolyn |
Cromolyn was discovered in 1965 by [[Roger Altounyan]], a [[Pharmacology|pharmacologist]] who had asthma. Altounyan was investigating certain plants and herbs which have bronchodilating properties. One such plant was [[khella]] (''Ammi visnaga'') which had been used as a muscle relaxant since ancient times in Egypt. Altounyan deliberately inhaled derivatives of the active ingredient [[khellin]] to determine if they could block his asthma attacks. After several years of trial, he isolated an effective and safe asthma-preventing compound called cromolyn sodium.<ref name="v055">{{cite journal | last=Kuzemko | first=J.A. | title=Twenty years of sodium cromoglycate treatment: a short review | journal=Respiratory Medicine | volume=83 | date=1989 | doi=10.1016/S0954-6111(89)80245-8 | pages=11–16}}</ref> |
