Anxiolytic agent (tranquilizer) of benzodiazepine series.

Pharmachologic effect

Mode of action - anticonvulsant, anxiolytic, myorelaxing, sleeping, sedative.


Increases the inhibitory effect of GABA on the transmission of nerve impulses. Stimulates benzodiazepine receptors located in the allosteric center of postsynaptic GABA receptors of the ascending activating reticular formation of the brainstem and intercalary neurons of the lateral horns of the spinal cord; Reduces the excitability of subcortical structures of the brain (limbic system, thalamus, hypothalamus), inhibits polysynaptic spinal reflexes.

Anxiolytic action is caused by the influence on the amygdala complex of the limbic system and is manifested in a decrease in emotional tension, easing anxiety, fear, anxiety.

The sedative effect is due to the influence on the reticular formation of the brainstem and the nonspecific nuclei of the thalamus and is manifested by a decrease in the symptomatology of neurotic origin (anxiety, fear).

The productive symptomatology of psychotic genesis (acute delusional, hallucinatory, affective disorders) practically does not affect, rarely a decrease in affective tension, delusional disorders.

Sleeping effect is associated with depression of the cells of the reticular formation of the brain stem. Reduces the impact of emotional, vegetative and motor stimuli, disturbing the mechanism of falling asleep.

Anticonvulsant action is realized by strengthening presynaptic inhibition, suppressing the spread of convulsive impulse, but does not relieve the excited state of the focus.

Central miorelaksiruyuschee effect due to inhibition of the polysynaptic spinal afferent inhibitory pathways (to a lesser extent, monosynaptic). Perhaps a direct inhibition of the motor nerves and muscle functions.



After oral intake is well absorbed from the digestive tract, TCmax - 1-2 hours Metabolised in the liver. T1 / 2 - 6-10-18 h. It is excreted mainly by kidneys in the form of metabolites.

Solution for IV and IM administration

Widely distributed in the body. Metabolised in the liver. T1 / 2 is excreted from 6 to 10-18 hours, the excretion of the drug is mainly carried out through the kidneys in the form of metabolites.

Application in pregnancy and breastfeeding

During pregnancy, use only for life indications. Has a toxic effect on the fetus and increases the risk of congenital malformations when applied in the first trimester of pregnancy. Admission of therapeutic doses in later periods of pregnancy can cause depression of the newborn's central nervous system. Continuous use during pregnancy can lead to physical dependence with the development of withdrawal syndrome in a newborn.

Children, especially at a young age, are very sensitive to the CNS depressing action of benzodiazepines.

The use of directly before childbirth or during labor can cause a respiratory depression in the newborn, a reduction in muscle tone, hypotension, hypothermia, and a weakening of the sucking act (a sluggish child syndrome).

Side effects


Sometimes there are memory impairments, concentration of attention, coordination of movements (especially at high doses), drowsiness, muscle weakness, ataxia, sometimes paradoxical agitation, dizziness, headache, dry mouth, nausea, diarrhea, menstrual irregularity, decreased libido, dysuria , Skin rash, itching.

With prolonged use (especially in high doses) - addiction, drug dependence.

Solution for IV and IM administration

From the nervous system: at the beginning of treatment (especially in elderly patients) - drowsiness, fatigue, dizziness, impaired concentration, ataxia, disorientation, slowing of mental and motor reactions, confusion; Rarely - headache, euphoria, depression, tremor, memory loss, impaired coordination of movements (especially at high doses), decreased mood, dystonic extrapyramidal reactions (uncontrolled movements, including the eye), asthenia, myasthenia gravis, dysarthria; Extremely rarely - paradoxical reactions (aggressive outbreaks, psychomotor agitation, fear, suicidal tendencies, muscle spasm, hallucinations, anxiety, sleep disturbance).

From the hemopoiesis: leukopenia, neutropenia, agranulocytosis (chills, hyperthermia, sore throat, unusual fatigue or weakness), anemia, thrombocytopenia.

On the part of the digestive system: dry mouth or salivation, heartburn, nausea, vomiting, decreased appetite, constipation or diarrhea; Impaired liver function, increased activity of hepatic transaminases and alkaline phosphatase, jaundice.

From the genitourinary system: urinary incontinence, urinary retention, impaired renal function, decreased or increased libido, dysmenorrhea.

Allergic reactions: skin rash, itching.

Influence on the fetus: teratogenicity (especially I trimester), CNS depression, respiratory failure and suppression of sucking reflex in newborns whose mothers took the drug.

Other: addiction, drug dependence, lowering blood pressure; Rarely - impaired vision (diplopia), weight loss, tachycardia. With a sharp decrease in dose or discontinuation of reception - withdrawal syndrome (sleep disturbance, dysphoric reactions, spasm of smooth muscles of internal organs and skeletal muscles, depersonalization, increased sweating, depression, nausea, vomiting, tremor, perception disorder, including hyperacusis, paresthesia , Photophobia, tachycardia, convulsions, rarely - psychotic reactions).

Local reactions: phlebitis or venous thrombosis (redness, swelling or pain at the injection site).


Phenorelaxan® is compatible with other drugs that cause depression of the functions of the central nervous system (hypnotics, anticonvulsants, neuroleptics, etc.), however, in case of complex application it is necessary to take into account the mutual enhancement of their functions.

Reduces the effectiveness of levodopa in patients with Parkinsonism.

May increase the toxicity of zidovudine.

Inhibitors of microsomal oxidation increase the risk of toxic effects.

Inducers of microsomal liver enzymes reduce efficacy.

Increases the concentration of imipramine in the serum.

Hypotensive drugs can increase the severity of blood pressure lowering.

Against the background of simultaneous administration of clozapine, an increase in respiratory depression is possible.

Additionally for tablets: there is a mutual enhancement of the effect with simultaneous appointment of central muscle relaxants, narcotic analgesics, ethanol.

Dosing and Administration

Tablets: Inside.

In case of sleep disturbance, 0.25-0.5 mg for 20-30 minutes before bedtime.

For the treatment of neurotic, psychopathic, neurotic-like and psychopathic conditions, the initial dose is 0.5-1 mg 2-3 times a day. After 2-4 days, taking into account the effectiveness and tolerability of the drug, the dose can be increased to 4-6 mg / day.
