The Introductction of Cyproheptadine hydrochloride:


Cyproheptadine hydrochloride is a kind of pipecolic antihistamines,it can compete with histamine released from the organization for H1 receptor on effector cells , thereby it can prevent the onset of an allergic reaction, and release histamine-induced spasm and congestion effects, this product has a strong H1 receptor antagonism, its anti-histamine effect is stronger than chlorpheniramine, promethazine . There are mild to moderate anti-serotonin effects and anticholinergic effects. In addition, there is a stimulate appetite effect, and weight gains after a certain time.


The Application & Function of Cyproheptadine hydrochloride:


1.Cyproheptadine HCL is a piperidine antihistamine. 

2.Cyproheptadine HCl does not prevent the release of histamine but rather competes with
free histamine for binding at HA-receptor sites.

3.Cyproheptadine HCL also competes with serotonin at receptor sites in smooth muscle in
the intestines and other locations. 

4.Cyproheptadine HCL also has been used to counter vascular headaches, which many
believe are caused by changes in serotonin activity, however it is unclear how Cyproheptadine
exerts a beneficial effect on this condition.
