Definition CSP histamine H1 antagonist used in allergic reactions, hay fever, rhinitis, urticaria, asthma and in veterinary applications; one of the most widely used of the classical antihistamines.
It has also been used to stimulate appetite and weight gain, and is "Sedating antihistamines ukc" studied in the treatment of weight loss caused by cancer and its treatment.
Cyproheptadine belongs to the family of drugs called antihistamines. Definition MSH A serotonin antagonist Sedating antihistamines ukc a histamine H1 blocker used as antipruritic, appetite stimulant, antiallergic, and for the post-gastrectomy dumping syndrome, etc. Definition CSP serotonin antagonist and histamine H1 blocker used as an antipruritic, appetite stimulant, antiallergic, and to treat the post-gastrectomy dumping syndrome.
Definition PDQ The hydrochloride salt of a synthetic methyl-piperidine derivative with antihistaminic and anti-serotoninergic properties.
Cyproheptadine competes with free histamine HA for binding at HA-receptor sites, thereby competitively antagonizing histamine stimulation of HA-receptors in the gastrointestinal tract, large blood vessels, and bronchial smooth muscle. This agent also competes with free serotonin for binding at serotonin receptor sites. Cyproheptadine exhibits anticholinergic and sedative properties and has been shown to stimulate appetite and weight gain.
Histamine H1 Antagonists C Definition NCI Any agent that binds to the histamine H1 receptor, thereby antagonizing Sedating antihistamines ukc mediated allergic reactions, such as bronchoconstriction, vasodilation and up-regulated capillary permeability.
Antihistamines are used to prevent fevers in patients receiving blood transfusions and to treat allergies, coughs, and colds. Definition MSH Drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine. Included here are the classical antihistaminics that antagonize or prevent the action of histamine mainly in immediate hypersensitivity.
They act in the bronchi, capillaries, and some other smooth muscles, and are used to prevent or allay motion sickness, seasonal rhinitis, and allergic dermatitis and to induce somnolence.

Hydroxyzine's antihistaminic effect is due to its metabolite, cetirizine, a potent H1 receptor antagonist and selective inhibitor of peripheral H1 receptors. This agent competes with histamine for binding H1-receptor sites on the effector cell surface. The sedative properties of hydroxyzine occur as a result of suppression of certain subcortical regions of the brain.
Secondary to its central anticholinergic actions, hydroxyzine may be effective as an antiemetic.
