CAS Code


Characteristics of the substance Chlordiazepoxide

Anxiolytic, benzodiazepine derivative.

White or light yellow fine crystalline powder. Almost nerastvorim in water, it is difficult soluble in alcohol; in the form of hydrochloride - soluble in water.


Pharmacological action - anxiolytic, miorelaxing, central, sleeping, sedative.

Interacts with specific benzodiazepine receptors located in the post-synaptic GABAA receptor complex in the cerebral cortex, almond-shaped nucleus, hippocampus, the hypothalamus, cerebellum, striatum and spinal cord. Increases the sensitivity of neuronal GABA receptors to GABA, enhances GABA neurotransmission, blocks polysynaptic reflexes.

After oral administration, it is well absorbed from the digestive tract (food slows down absorption); Cmax when administered to a single dose is achieved after 0.5-4 h, the equilibrium concentration in the blood is reached after 5-12 days after the start of admission. Binding to plasma proteins is 96%. T1 / 2 of chlordiazepoxide from plasma is 7-28 h, Cmax of the main metabolite (desmethylchlorodiazepoxide) is 8-24 h. In the liver it is subjected to intensive metabolism (N-demethylation, deamination, hydroxylation) to form active derivatives (desmethylchlorodiazepoxide, demoxepam, desmethyldiazepam, oxazepam ). Passes through GEB, placenta, penetrates into breast milk; is slowly absorbed from the muscle tissue. After the end of treatment, metabolites are detected in the plasma for several days or even weeks. T1 / 2 - 5-30 h (chlordiazepoxide), 18 h (desmethylchlorodiazepoxide), 14-95 h (demexepam), 30-100 h (desmethyldiazepam), 5-15 h (oxazepam). It is excreted mainly by the kidneys (1-2% unchanged). The accumulation of chlordiazepoxide and its active metabolites with repeated application is considerable.

In the elderly, the absorption and metabolism of chlordiazepoxide proceed more slowly, the metabolic transformations slow down considerably when the liver is damaged.

Has a pronounced soothing effect on the central nervous system. Suppresses anxiety, excitement, emotional tension. Relieves obsessive thoughts and fears, increases susceptibility to hypnosuggestive therapy. Has an anti-panic effect, removes tremor, has a weak anticonvulsant effect. Reduces the severity of anxiety and fear associated with the upcoming surgical intervention.

In large doses can reduce psychomotor agitation. It shows a mild hypnotic effect, which is usually expressed in the first 3-5 days of therapy, in the future a positive effect on sleep is due to the elimination of various psychogenic stimuli. Causes mild muscle relaxation.

It alleviates the symptoms of acute alcohol withdrawal, such as agitation, nervous tension, anxiety anxiety, tremor, etc. Increases appetite, has a mild analgesic effect.

A study of reproduction in animals showed that the administration of chlordiazepoxide to rats at doses of 10, 20 and 80 mg / kg / day did not cause congenital malformations and neonatal growth disorders, as well as lactation in females. In another study, when doses of 100 mg / kg / day were administered, a significant reduction in the fertilization rate was observed, a marked decrease in survival and body weight in newborn rats.

Application of the substance Chlordiazepoxide

Neurotic conditions accompanied by anxiety, excitement, increased irritability, emotional stress, insomnia; neurotic ataxia, tension headache, cardialgia, esophagospasm, causalgia, facial hemispasm, hysterical conditions (hysterical fit, amblyopia, mutism, paralysis), psychogenic stupor, hiccough; neurotic and psychopathic disorders in patients with atherosclerosis of cerebral vessels, organic brain damage; infectious delirium, withdrawal syndrome in patients with alcoholism and drug addiction; increased tone of skeletal muscles, hyperkinesia rheumatic and neurotic; menopause, premenstrual syndrome, vegetative-vascular dystonia; premedication (preparation of patients for operations and long-term diagnostic procedures), postoperative period; complex therapy for schizophrenia with neurosis-like symptoms, as well as for diseases accompanied by itching, irritability, insomnia, incl. eczema.


Hypersensitivity, severe myasthenia gravis, respiratory depression, angle-closure glaucoma, acute liver and / or kidney disease, pregnancy (I trimester), breast-feeding, age 4 years.

Restrictions on the use

Glaucoma, impaired liver and / or kidney function, sleep apnea syndrome, severe cardiac and respiratory failure, ataxia (except neurotic), psychoses (possibly paradoxical enhancement of symptoms), drug or alcohol dependence (with the exception of acute withdrawal syndrome), pregnancy II and III trimester), the elderly.

Application in pregnancy and lactation

Contraindicated in the first trimester of pregnancy (increases the risk of congenital malformations during appointment in this period). In the second and third trimester of pregnancy is possible, if the expected effect of therapy exceeds the potential risk to the fetus. For the duration of treatment, breastfeeding should be stopped.

Side effects of the substance Chlordiazepoxide

From the nervous system and sense organs: drowsiness, lethargy, memory impairment and concentration of attention, slowing of mental and motor reactions, muscle weakness, gait disturbance, ataxia, confusion, disorientation, dizziness, headache, EEG changes.

From the cardiovascular system and blood (hematopoiesis, hemostasis): tachycardia, palpitation, arterial hypotension (with high doses), thrombocytopenia, agranulocytosis.

On the part of the intestine: dry mouth, nausea, constipation or diarrhea, intestinal colic, a violation of the liver, icterus of the skin.

Allergic reactions: skin rash, itching, scaling of the skin.

Other: difficulty breathing, urinary retention, menstrual irregularity, changes in libido (increase or decrease).

Possible addiction, drug dependence, withdrawal syndrome, etc. (see "Precautions").


Strengthens the effect of alcohol and drugs that depress the central nervous system (narcotic analgesics, anesthetic, hypnotics, neuroleptics with pronounced sedative effect), muscle relaxants, etc. Antacid agents slow the absorption (but not reduce the absorption) of chlordiazepoxide. Chlordiazepoxide can reduce the effect of levodopa. Cimetidine, estrogen-containing oral contraceptives, disulfiram and erythromycin slow the metabolism of chlordiazepoxide in the liver, increase its concentration in the blood and delay excretion. Smoking can weaken the action of chlordiazepoxide.


Symptoms: depression of the central nervous system of varying degrees of severity (from drowsiness to coma) - pronounced drowsiness, lethargy, weakness, decreased muscle tone, prolonged confusion, disorientation, indiscriminate speech, oppression of reflexes, coma; respiratory depression and hypotension are also possible.

Treatment: induction of vomiting, immediate gastric lavage, monitoring of vital functions, symptomatic therapy, intravenous infusion of solutions (to enhance diuresis), ensuring adequate ventilation of the lungs; in the case of hypotension, the administration of norepinephrine. When developing excitation, barbiturates should not be used. As a specific antidote, a benzodiazepine receptor antagonist, flumazenil (in a hospital setting) is used. Hemodialysis is ineffective.

Routes of administration


Precautions for the substance Chlordiazepoxide

It should be noted that when combining anxiety with depression, suicidal attempts are possible.

Use with caution at the same time as other psychotropic drugs. Do not administer simultaneously with MAO inhibitors and phenothiazines.

With prolonged use (for several months), especially in high doses, addiction and drug dependence are possible. The abolition of chlordiazepoxide should be carried out gradually, by lowering the dose to reduce the risk of withdrawal syndrome characterized by tremors, seizures, abdominal or muscle spasms, vomiting, sweating. With a sharp cancellation are also possible psychomotor agitation, fear, vegetative disorders, insomnia.

Do not take chlordiazepoxide over 4 weeks without reevaluating the patient to make a decision about the need to continue therapy.

The likelihood of side effects is higher in the elderly.

With prolonged use, it is necessary to periodically monitor the picture of peripheral blood and liver function.

There have been reports that paradoxical reactions (psychomotor agitation, fits of rage, etc.) were observed in the treatment of chlordiazepoxide by mentally ill patients and children with aggressive behavioral features. In case of development of paradoxical reactions treatment should be stopped immediately.

It should be borne in mind that chlordiazepoxide can reduce the liveliness of the mind in children.

It should be borne in mind that there are reports of an effect on blood coagulation in patients taking concurrent oral anticoagulants and chlordiazepoxide (in clinical studies, the cause and consequences of this interaction are not established). There are some reports of exacerbation of porphyria under the action of chlordiazepoxide. Hypoproteinemia may predispose to an increased incidence of sedative side effects.

During treatment and within 3 days after its withdrawal, it is necessary to exclude the intake of alcoholic beverages; drivers of vehicles and people whose work requires a quick mental and physical reaction, and is associated with increased concentration of attention, during this period should not engage in professional activities.

Special instructions

Disturbing conditions and stress associated with everyday life stress, usually do not require treatment with anxiolytics.
