pharmachologic effect
The tablets contain a medicinal substance that is a derivative of 1,4-benzodiazepine and has sedative , anticonvulsant and anxiolytic effects.
The action of the active substance is associated with the receptor complex. It includes gamma-aminobutyric acid, GAM-A receptor, benzodiazepine receptor and chloride channel. The active substance inhibits several structures in the central nervous system, in particular the spinal column, limbic system, cerebral cortex, hypothalamus and cerebellum. This substance has a strong anxiolytic effect, hypnotic and sedative activity, reduces the severity of seizures and the tone of skeletal muscles.
Relium in ampoules has hypnotic, anticonvulsant, sedative and anxiolytic effects. The action of the active substance is to influence GABA-A receptors and gamma-aminobutyric acid, which is an endogenous neurotransmitter involved in inhibition processes in the central nervous system. When using the solution, patients experience a decrease in seizures and slight relaxation of skeletal muscles. It also has some hypnotic effects.
Pharmacodynamics and pharmacokinetics
Bioavailability after oral administration is 98 percent. The maximum level of the active substance in the serum is observed after 0.9-1.3 hours and is 500 ng/ml. The main part of the active substance in the serum is in bound form. The half-life lasts up to two days. Diazepam penetrates the blood-brain and blood-placental barriers, and is also detected in small amounts in breast milk. Metabolization occurs in the liver and is excreted through the urinary system.
When administered by injection, high concentrations of the active substance are observed in amniotic and synovial fluids, as well as in breast milk. This substance tends to accumulate in adipose tissue and is subsequently released into the bloodstream. Approximately 25 percent is excreted unchanged.
Indications for use of Relium
Indications for use are as follows:
- neuroses , anxiety , restlessness , borderline states with manifestations of tension;
- tetanus , premature placental abruption, premature birth , facilitation of labor;
- premedication before anesthesia;
- status epilepticus;
- arthritis , bursitis , myositis , which are accompanied by tension in the skeletal muscles, spastic conditions that are associated with damage to the spinal cord and brain;
- withdrawal syndrome in chronic alcoholism, motor excitation of various etiologies in psychiatry and neurology, sleep disorders;

Special instructions for use
Take special care in patients with cardiac and respiratory failure, organic changes in the brain (in such cases, it is recommended to avoid parenteral administration of diazepam), with closed-cuta glaucoma and pre-clinical glaucoma , with myasthenia. Particular care is required when taking diazepam, especially during treatment, in patients who have been taking centrally administered antihypertensive drugs, beta-blockers, anticoagulants, and cardiac glycosides. When changing therapy, the dose should be changed step by step. When administered with a diazepam after a period of severe congestion, you may experience restlessness, restlessness, tremor, and seizures. Diazepam should be discontinued if paradoxical reactions develop (excitement, anxiety, sleep disturbance and hallucinations). After intramuscular injection of diazepam, there may be an increase in the activity of CPK in the blood plasma (which can be observed in the differential diagnosis of myocardial infarction). Unique in / a introduction. During the feast period, do not allow alcohol to take hold. By introducing Diazepam to the building before water transport and water treatment mechanisms, Diazepam can result in increased fluidity of psychomotor reactions, which should be used to protect patients who are engaged in potentially unsafe types of activities. i.

Overdose
In case of overdose, dysarthria , nystagmus , drowsiness and ataxia . apnea , coma , depression of cardiac and vascular function, and arterial hypotension can also sometimes be observed . In people with diseases of the respiratory system, with an overdose, respiratory depression becomes more pronounced.
Treatment consists of eliminating symptoms, supportive therapy (carrying out artificial respiration (in the absence of consciousness), monitoring the functions of the cardiovascular, nervous and respiratory systems). To reduce the absorption of diazepam, enterosorbents are prescribed (gastric lavage is not recommended).
Possible side effects and overdose
No matter how ideally the treatment regimen is selected, there is a risk of unwanted symptoms. The most common side effects are:
- from the central nervous system - headache, dizziness, pressure in the temporal region or the back of the head, disturbances in orientation in space, dyslalia;
- from the digestive tract - nausea, vomiting, constipation, diarrhea, epigastric pain, increased gas formation, yellowness of the skin;
- from the cardiovascular system – arterial hypotension;
- dermatological problems – itching, rash, dermatitis;
- the occurrence of paradoxical reactions - hallucinations, delirium, increased tone, insomnia (such symptoms are a direct indication for discontinuation of the medication).
Symptoms of a drug overdose are:
- excessive sleepiness;
- weakness;
- disturbance of consciousness;
- decreased reflexes;
- apnea;
- coma.
When the first signs of an overdose appear, the patient should be given immediate assistance, following the following algorithm:
- Stop taking the drug.
- Give the person a comfortable position.
- Rinse the stomach with plenty of distilled water.
- Give any sorbent (white carbon, activated carbon).
- While providing assistance, be sure to monitor your pulse, blood pressure, and respiration.
- Call an ambulance (if signs appear at home), which will provide venous access for adequate infusion therapy.
- Use a specific antidote - flumazenil (with its use there is a high risk of seizures).
Interaction
Concomitant use with drugs that depress the central nervous system (including opioid analgesics , hypnotics , sedatives , antipsychotics and anesthetics respiratory center, and also contributes to the development of severe arterial hypotension .
Simultaneous use with ethanol or drugs containing ethanol enhances the inhibitory effect on the central nervous system (especially the respiratory center) and contributes to the development of pathological intoxication syndrome.
Concomitant use with disulfiram , omeprazole , cimetidine increases the intensity and duration of exposure to diazepam.
Concomitant use with fluvoxamine increases plasma concentrations and side effects of diazepam.
Phenytoin and phenobarbital accelerate the metabolism of diazepam, and rifampicin increases its elimination. Paracetamol reduces the excretion of diazepam, and simultaneous use with risperidone promotes the development of NMS.
Simultaneous use with metoprolol leads to a deterioration of psychomotor reactions and a decrease in visual acuity, with lithium carbonate - leads to the development of a coma, with levodopa - suppresses the antiparkinsonian effect, with clozapine - causes loss of consciousness, respiratory depression and severe arterial hypotension, with diclofenac - causes increased dizziness, with bupivacaine - increases its concentration in the blood plasma, with oral contraceptives - enhances the effect of diazepam and can lead to breakthrough bleeding , with muscle relaxants - enhances their effect and increases the risk of apnea , with tricyclic antidepressants (including amitriptyline ) - enhances a depressant effect on the central nervous system, enhances the cholinergic effect and increases the concentration of antidepressants.
Simultaneous use with caffeine reduces the sedative and anxiolytic effects of the drug. Medicines that cause induction of liver enzymes, including anti- epileptic ( phenytoin , carbamazepine ), accelerate the elimination of diazepam.
In people who have been taking cardiac glycosides , anticoagulants , beta-blockers , and antihypertensive drugs , the mechanisms and extent of drug interactions may be unpredictable.
Interaction with other drugs and special instructions
Relium should be used with extreme caution simultaneously with phenothiazine derivatives, narcotic analgesics, hypnotics and antidepressants. Such combinations enhance the effect of the main component of Relium - diazepam.
It is prohibited to consume alcohol and drugs during treatment with Relium, since in such a situation the nervous system is significantly depressed and a syndrome of pathological intoxication occurs, which does not depend on the amount of alcohol consumed. This condition is quite often fatal.
Oral contraceptives (COCs) inhibit the effect of the medication. The process of smoking during the treatment period has the same effect.
Concomitant use with other drugs does not cause significant changes in the pharmacodynamics of Relium. However, clinical trials on this matter are ongoing.
Any treatment with this drug should be carried out under the strict supervision of medical personnel. It is prescribed with caution for the treatment of depressive disorders, since there is a high probability of suicidal tendencies in the patient’s behavior.
Clinical and laboratory parameters of the blood and urine system should be monitored periodically during therapy. Particular attention should be paid to changes in liver function tests. The drug is withdrawn gradually.
