Asfen (1mg) 30 Tablets

Ketotifen, the active ingredient in Ketotifen tablets, primarily acts as a selective histamine H1-receptor antagonist, effectively blocking the effects of histamine in various tissues. Its mechanism of action involves binding to H1-receptors, thereby preventing histamine-induced responses. This action helps to stabilize mast cells, reducing the release of inflammatory mediators such as histamine, leukotrienes, and prostaglandins. By inhibiting the activation of mast cells, Ketotifen suppresses allergic reactions and exhibits anti-inflammatory properties. Additionally, Ketotifen has been shown to have some affinity for other receptors, including H2 and H3 histamine receptors, and may exert its effects through these pathways as well, contributing to its overall therapeutic action.
