🔬 How This Medicine Works (Pharmacology)

DistributionIt is widely distributed throughout the body, including the central nervous system.
Protein BindingApproximately 96% bound to plasma proteins.
MetabolismExtensively metabolized in the liver, primarily via glucuronidation.
Half-LifeThe elimination half-life is approximately 8 hours.

Duration of ActionThe effects typically last for 4 to 8 hours, but may persist longer due to the half-life.

How It Works

Cyproheptadine is a first-generation antihistamine that competitively blocks histamine H1 receptors. It also antagonizes serotonin (5-HT2) receptors. By blocking H1 receptors, it reduces allergic symptoms such as vasodilation, increased vascular permeability, and itching. Its antiserotonergic action contributes to appetite stimulation and may help in migraine prophylaxis. Additionally, it has anticholinergic properties, which can cause dry mouth, blurred vision, and constipation.

Mechanism Steps

1
Histamine H1 receptor blockade: Cyproheptadine binds to H1 receptors on smooth muscle and endothelial cells, preventing histamine from inducing vasodilation, increased permeability, and itching.
2
Serotonin 5-HT2 receptor antagonism: It blocks serotonin receptors in the brain, which may contribute to appetite stimulation and migraine prevention.
3
Anticholinergic effects: It also blocks muscarinic acetylcholine receptors, leading to dry mouth, blurred vision, and constipation.
