Pemirolast Potassium is the potassium salt form of pemirolast, a pyrimidinone derivative with antiallergic property. Pemirolast potassium exerts its action by blocking the antigen-mediated calcium ion influx into mast cells. This prevents mast cell degranulation, resulting in mast cell stabilization and inhibition of the release of inflammatory mediators, histamine and leukotrienes, which are involved in the allergic process. Pemirolast potassium also prevents inflammatory mediator release from eosinophils.

4 Pharmacology and Biochemistry

4.1 MeSH Pharmacological Classification

Histamine Antagonists

Drugs that bind to but do not activate histamine receptors, thereby blocking the actions of histamine or histamine agonists. Classical antihistaminics block the histamine H1 receptors only. (See all compounds classified as Histamine Antagonists.)
