cyproheptadine

Description:
Cyproheptadine is an antihistamine with antiserotonergic properties, primarily used to treat allergic reactions, such as hay fever and urticaria, as well as to stimulate appetite in certain conditions. It is classified as a first-generation antihistamine, which means it can cross the blood-brain barrier, often leading to sedative effects. The chemical structure of cyproheptadine includes a bicyclic structure with a piperidine ring, contributing to its pharmacological activity. It is typically administered orally and is known for its relatively long half-life, allowing for once or twice daily dosing. Common side effects may include drowsiness, dizziness, and dry mouth, which are typical of many first-generation antihistamines. Cyproheptadine is also sometimes used off-label for conditions such as migraines and serotonin syndrome due to its ability to block serotonin receptors. Its CAS number, 129-03-3, uniquely identifies this compound in chemical databases, facilitating research and regulatory processes.
