How It Works

Competitive antagonist of histamine at H1 receptor sites, thereby suppressing histamine-mediated allergic symptoms.

Mechanism Steps

1Chlorpheniramine binds to histamine H1 receptors on target cells (e.g., respiratory epithelium, vascular endothelium).
2Competitive antagonism prevents histamine from binding and activating the receptor.
3Inhibition of histamine-mediated vasodilation, increased vascular permeability, and smooth muscle contraction.
