How It Works

This medicine works by competitively blocking histamine H1 receptors and serotonin 5-HT2 receptors. By blocking these receptors, it prevents histamine and serotonin from exerting their effects, which reduces allergic symptoms such as itching, sneezing, and vasodilation. Its antagonism of serotonin receptors in the brain may also contribute to appetite stimulation and migraine prevention.

Mechanism Steps

1
Histamine H1 receptor blockade: This medicine binds to histamine H1 receptors on cells, preventing histamine from binding and triggering allergic responses.
2
Serotonin 5-HT2 receptor blockade: It also blocks serotonin 5-HT2 receptors in the brain, which may contribute to its appetite-stimulating and migraine-preventive effects.
3
Anticholinergic effects: This medicine has anticholinergic properties that contribute to dry mouth, blurred vision, and constipation.
4
Central nervous system depression: It causes sedation by depressing the central nervous system, leading to drowsiness.
