What drug class is ketotifen?
Ketotifen belongs to the class of medicines called mast cell stabilizers. It is also described as an antihistamine (H1 blocker) because it blocks histamine’s effects and helps prevent mast cells from releasing inflammatory mediators. [1]
Is ketotifen an antihistamine or a mast cell stabilizer?
Ketotifen is both in practical terms:
- As a mast cell stabilizer, it helps reduce inflammatory mediator release from mast cells.
- As an H1 antihistamine, it counteracts histamine-driven allergy symptoms. [1]
What is ketotifen typically used for (class-related indications)?
Because it targets histamine and mast cell activity, ketotifen is used for allergic conditions, most commonly allergic conjunctivitis (with eye formulations) and sometimes for allergic symptoms involving the airways depending on the product and country. [1]
Does ketotifen differ from other allergy “types”?
Yes. Compared with “classic” antihistamines (which mainly block H1 receptors), ketotifen’s additional mast cell stabilizing action is part of what defines its drug profile as a mast cell stabilizer as well as an antihistamine. [1]
