Introduction | cyproheptadine hydrochloride, also known as diphenylcycloheptadine, metapantin, ethylphenylcycloheptadine, A hexahydropyridine antihistamine that competes with histamine released from tissues for H1 receptors on effector cells, thereby preventing the onset of allergic reactions, relieve histamine induced spasmolysis and hyperemia, the goods have a strong H1 receptor antagonism, antihistamine effect than chlorpheniramine, promethazine strong. Mild to moderate anti-serotonin and anti-cholinergic effects. In addition, there is the role of stimulating appetite, after a certain period of time visible weight gain. |
indications | cyproheptadine hydrochloride hemihydrate is mainly used for acute and chronic urticaria (especially cold urticaria has good effect), papular urticaria, angioedema, allergic eczema, contact dermatitis, food allergy, drug allergy, allergic rhinitis, hay fever, allergic conjunctivitis, insect sting allergy and migraine. It has a certain therapeutic effect on bronchial asthma. Can be used for Cushing's syndrome, acromegaly adjuvant therapy. It can also be used as an appetite enhancer for anorexia nervosa. Treatment of acanthosis nigricans and prevention of necrotizing pyoderma have been reported. |
dosage | oral dosage form (1) allergic diseases: adults, 2~4mg once, 2-3 times a day. (2) hypercortisolism, suitable for the treatment of bilateral adrenal hyperplasia, which can inhibit the release of corticotropin-releasing hormone (CRH) from hypothalamus and pituitary adrenocorticotropic hormone (ACTH) the secretion, thereby reducing the level of plasma ACTH and cortisol; Adults start 8mg a day, can be gradually increased to 24mg a day; The commonly used dose is 12~24mg a day, divided into doses, need long-term application; in the case of insufficient cortical function after bilateral total or Subtotal adrenalectomy, on the one hand, adding corticosteroids, on the other hand, taking cyproheptadine can reduce the chance of pituitary tumor. |
