Cromolyn

The attractive properties of cromolyn as an inhibitor of the release of mediators of anaphylaxis has inspired many attempts to improve on the antiasthmatic characteristics of that substance. One such agent is cromitrile (6). In this case, a tetrazolyl unit is introduced as a carboxy group... 

The discovery of the utility of the bis-chromone carboxylic acid derivative cromolyn sodium in the treatment of asthma and related allergies has led to an intensive, and thus far not very fruitful, effort to discover analogues which would show oral activity in contrast to the lead which must be administered by inhalation. Preparation of a typical analogue, proxicromil (63), starts with the O-allylated phenol 57. Claisen rearrangement leads to the corresponding C-allylated product 58.

Cromones are used to prevent asthma attacks. To be effective they have to betaken continuously. Their mechanism of action is poorly understood. Cromones (cromolyn sodium, nedocromil) act as mast cell-stabilizing agents,... 

Mast cell stabilizers include cromolyn sodium (Intal) and nedocromil sodium (Tilade). 

Occasionally Hie patient may experience an acute bronchospasm either as a result of the disease after exposure to an allergen, or as an adverse reaction to some antiasthma dragp, such as cromolyn inhalation. 

When administered orally, cromolyn is given 1/2 hour before meals and at bedtime The oral form of the drug comes in an ampule The ampule is opened and the contents poured into a glass of water. The nurse stirs the mixture thoroughly. The patient must drink all of the mixture The drug may not be mixed with any other substance (eg, fruit juice, milk, or foods). 

Cromolyn—When taken to prevent exercise-induced asthma, this drug should be taken approximately 15 minutes before activity but no earlier than 1 hour before the expected activity.

In persistent asthma, inhaled corticosteroids provide the most comprehensive control of the inflammatory process and are the cornerstone of therapy.2 Inhaled corticosteroids are more effective than cromolyn, leukotriene modifiers, nedocromil, and theophylline in reducing markers of inflammation and AHR, improving lung function, and preventing emergency department visits and hospitalizations due to asthma exacerbations.2,25 The primary... 

Cromolyn and nedocromil are inhaled anti-inflammatory agents that block both the early- and late-phase response. Both agents are considered alternative therapies to inhaled corticosteroids for the treatment of mild persistent asthma however, both are less effective than low doses of inhaled corticosteroids.2,30 The exact mechanism of action of these agents is not understood, but they appear to inhibit mast cell mediator release as well as modulate other inflammatory responses.3... 

Patients receiving these agents may notice improvement in 1 to 2 weeks, but maximal benefit may not be seen for 4 to 6 weeks. Cromolyn and nedocromil appear to be similar in efficacy to the leukotriene antagonists and theophylline for persistent asthma.18 Both agents are well tolerated with adverse effects limited to cough and wheezing. Bad taste and headache have also been reported with nedocromil. One dose of cromolyn or nedocromil prior to exercise or allergen exposure will provide effective prophylaxis for 1 to 2 hours. Cromolyn and nedocromil are not as effective as albuterol for prophylaxis of exercise-induced asthma.
