Pemirolast (Alamast) falls under which classification?

Pemirolast, marketed under the name Alamast, is classified as a mast cell stabilizer. This classification is important because mast cell stabilizers work by preventing the release of histamine and other inflammatory mediators from mast cells, which play a key role in allergic reactions and asthma. By stabilizing these cells, pemirolast helps to reduce symptoms associated with allergic conjunctivitis and other allergic conditions.

Mast cell stabilizers are particularly useful in managing allergies because they offer a preventive approach, reducing the likelihood of symptoms before exposure to allergens. This is distinct from other classes like antihistamines, which block the action of histamine after it has been released. Understanding this mechanism is crucial for effective allergy management and treatment options.
