🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Chlorpheniramine maleate works by competitively blocking histamine H1 receptors on effector cells in the conjunctiva, thereby reducing the allergic response such as itching, vasodilation, and increased vascular permeability. Camphor, when applied topically to the eye, acts as a mild local analgesic and counterirritant, producing a cooling sensation that helps distract from irritation and provides temporary relief. The combination targets both the allergic component and the sensory discomfort.
