TOTIFEN CAP (KETOTIFEN)

Ketotifen, the active ingredient in Ketotifen capsules, primarily acts as a selective histamine H1 receptor antagonist, effectively blocking the effects of histamine in the body. Its mechanism of action involves binding to H1 receptors, which leads to a decrease in histamine-induced symptoms. By inhibiting the action of histamine, Ketotifen helps to stabilize mast cells, reducing their release of inflammatory mediators such as histamine, leukotrienes, and prostaglandins. This anti-inflammatory effect is crucial in alleviating symptoms associated with allergic reactions and asthma. Additionally, Ketotifen has been shown to possess mast cell-stabilizing properties, further contributing to its effectiveness in managing allergic conditions by preventing the release of allergic substances from mast cells.
