Chemical Class: Dioxamic acid derivative; mast cell stabilizer ▪ Clinical Pharmacology: Mechanism of Action: A mast cell stabilizer that prevents increase in cutaneous vascular permeability, antigen-stimulated histamine release, and may prevent calcium influx into mast cells. Therapeutic Effect: Inhibits...

Successful anti-allergic therapies have typically targeted mast cell mediators, particularly histamine. Antihistaminic compounds interact with the various ...
I need to pre-medicate, beginning in July, with small amounts of Zyrtec, Ketotifen (a mast cell stabilizer that also helps keep eosinophils at bay), and Nasalcrom. I slowly increase the dosage of these medications as I move into Fall to manage pollen allergies and MCAS symptoms. For me,...
–Diagnosing mast cell conditions is not simple. Many practitioners falsely believe that a normal tryptase is indicative of no mast cell disorder. Patients sometimes get diagnoses (MS, lupus, anxiety, interstitial cystitis and more) that reflect one arm of mast cell problems, only to find out la...
To test whether pruritus resulted from mast cell activation, we injected PAMP9-20 into both cromolyn-treated and cKitW-sh (SASH) mice. Cromolyn is a mast cell stabilizer that inhibits granule release, while SASH mice are c-Kit receptor-deficient animals that lack mast cells. Both cromolyn-...
Symptoms of mastocytosis occur when pharmacologic or physical stimuli cause mast cell degranulation with release of histamine, prostaglandin D2 (PGD2), leukotrienes, heparin, and proteolytic enzymes. Ocular involvement in mastocytosis has been previously documented.1,2,3 We report a patient with ...
Cnfs are occasionally accompanied by severe and persisting pruritus which can be partly attributed to mast cell (MC) degranulation. Ketotifen, a relatively selective second-generation noncompetitive H1-antihistamine and mast cell stabilizer, has not yet been fully appreciated for its potential in NF1...
As used herein, the term “antihistamine” refer to drugs which treat allergic rhinitis and other allergies. By a “therapeutically effective amount” of the mast cell stabilizer of the invention as above described is meant a sufficient amount of the compound. It will be understood, however, tha...
