CAS Code


Characteristics of the substance Cyproheptadine

Ciproheptadine hydrochloride is a white or slightly yellowish crystalline powder, soluble in water and chloroform, easily soluble in methanol, sparingly soluble in ethanol and practically insoluble in ether. Molecular weight is 350.89.


Pharmacological action - antiallergic, antihistamine, antiserotonin.

It blocks histamine H1 receptors. Reduces the body's reaction to histamine, prevents and alleviates the course of allergic reactions. Reduces the permeability of capillaries, prevents the development of edema of tissues. Has a pronounced antiserotonin, weak m-holinoliticheskoe and sedative effect. Reduces hypersecretion of somatotropin in acromegaly and ACTH release in Isenko-Cushing syndrome.

In experimental studies, there was no mutagenic and teratogenic effect, effects on fertility.

When ingested quickly and completely absorbed from the digestive tract. Cmax is reached within the first 2 hours, the therapeutic level in the plasma is kept 4-6 hours. It is evenly distributed in the body, penetrates into the central nervous system. Intensively metabolized (hydroxylation followed by the formation of conjugates with glucuronic acid) in the liver. After a single application in a dose of 4 mg (in the form of tablets or syrup), 2-20% is excreted by the intestine (of which 34% is unchanged) and at least 40% is excreted in the urine. With repeated daily use in doses of 12-20 mg (as a syrup), the unchanged form of the drug in the urine is not detected. The main metabolite found in urine is identified as a quaternary ammonium conjugate of cyproheptadine with glucuronic acid. With renal failure, the elimination slows down.

Application of the substance Cyproheptadine

Hives (acute, chronic and cold), pollinosis, serum sickness, year-round or seasonal allergic rhinitis, allergic conjunctivitis, angioedema; Allergic reactions to taking medicinal and radiocontrast agents, blood transfusions, insect bites; Skin diseases - itching dermatoses, contact dermatitis, toxicodermia, neurodermatitis, eczema; Headache of vascular origin (migraine), vasomotor rhinitis; Anorexia, cachexia (in the period of convalescence, with chronic diseases), complex therapy of chronic pancreatitis.


Hypersensitivity, zakratougolnaya glaucoma, benign prostatic hyperplasia, urinary retention, pyloroduodenal obstruction, stenosing peptic ulcer, predisposition to edema, simultaneous use with MAO inhibitors, elderly patients, pregnancy, breast-feeding, breast age (up to 6 months).

Application in pregnancy and lactation

The action category for fetus by FDA is B.

For the duration of treatment, breastfeeding should be stopped.

Side effects of the substance Cyproheptadine

From the nervous system and sensory organs: weakness, sedation and drowsiness (often transient), anxiety, headache, dizziness, ataxia, visual hallucinations.

From the cardiovascular system and blood (hematopoiesis, hemostasis): hypotension, tachycardia, hemolytic anemia, leukopenia, agranulocytosis.

On the part of the intestine: dry mouth, nausea, vomiting, diarrhea.

Allergic reactions: rash, Quincke's edema, hives, anaphylaxis, photosensitivity.

Other: weight gain.


Caffeine reduces the inhibitory effect of cyproheptadine on the CNS; Additive effect can be observed with the joint application of cyproheptadine with ethyl alcohol and other substances that depress the central nervous system (sedatives, hypnotics, anxiolytics). Simultaneous use of cyproheptadine with other drugs that depress the central nervous system requires constant monitoring of the patient and withdrawal of the drug if necessary. The combined use of cyproheptadine with fluoxetine and other inhibitors of reverse neuronal seizure of serotonin leads to a decrease in the effectiveness of antidepressants. Contraindicated simultaneous use of cyproheptadine with MAO inhibitors. MAO inhibitors, as well as tricyclic antidepressants, can prolong and intensify the m-cholinoblocking effect of cyproheptadine, and enhance the inhibitory effect on the CNS.


Symptoms: in children - mydriasis and the immobility of the pupils, hyperemia of the facial skin, hyperthermia, agitation, anxiety, hallucinations, ataxia, athetosis, convulsions, collapse, coma; In adults - inhibition, depression, coma, or psychomotor agitation, convulsions; Rarely - hyperthermia and hyperemia of the skin.

Treatment: induction of vomiting, the appointment of activated charcoal inside, followed by gastric lavage; With the development of life-threatening symptoms from the side of the central nervous system or pronounced atropine-like effects - the introduction of a solution of physostigmine salicylate; By indications - vasoconstrictor and anticonvulsant drugs, mechanical ventilation, and other resuscitation measures. Psychostimulants and analeptic agents are contraindicated.

Routes of administration


Precautions for the substance Cyproheptadine

The first reception is recommended in the evening, after eating (sedative effect is characteristic for the beginning of treatment). Caution is prescribed for children and elderly patients (hypersensitivity is possible), patients with a history of bronchial asthma, hyperthyroidism, increased intraocular pressure, arterial hypertension and other cardiovascular diseases.

During course treatment you cannot drink alcohol.

It can be used in conjunction with narcotic analgesics, anxiolytics (under strict medical supervision) for complex preoperative preparation of patients, t. Cyproheptadine potentiates the effect of these drugs with simultaneous application and prevents the development of undesirable effects of histamine (arterial hypotension, bronchospasm), which is released as a result of traumatization of body tissues during surgery.

Do not use during work drivers of vehicles and people whose profession is associated with increased concentration of attention, especially in the initial, individually defined, treatment period.
