Note that the drug named cyproheptadine hydrochloride generally refers to cyproheptadine hydrochloride sesquihydrate. A sedating antihistamine with antimuscarinic and calcium-channel blocking actions, it is used for the relief of allergic conditions including rhinitis, conjunctivitis due to inhalant allergens and foods, urticaria and angioedema, and in pruritic skin disorders. Unlike other antihistamines, it is also a seratonin receptor antagonist, making it useful in conditions such as vascular headache and anorexia. It has a role as a serotonergic antagonist, an antipruritic drug, an anti-allergic agent, a gastrointestinal drug and a H1-receptor antagonist. It contains a cyproheptadine hydrochloride (anhydrous)."}]
