Sezolep is an antiepileptic drugs from the group of benzodiazepine derivatives. This medication has a pronounced anticonvulsant and central muscle relaxant, anxiolytic, sedative and hypnotic effects.

Anxiolytic effects of this drug is due to the influence on the amygdaloid complex of the limbic system and appears in reducing the emotional stress, reduce anxiety, fear, anxiety.

The sedation effects is due to the influence on the reticular formation of the brainstem and nonspecific thalamic nucleus and manifests a decrease in neurotic symptoms.

The central muscle relaxant effect is due to inhibition of spinal polysynaptic afferent inhibitory ways (to a lesser extent and monosynaptic).

It is possibly and direct inhibition of motor nerves and muscle function.

Cardiovascular system: decreased blood pressure, tachycardia.

Endocrine: changes in libido, dysmenorrhea, reversible premature sexual development in children (part-time early puberty).

Respiratory system: with / in the introduction possible respiratory depression, particularly after treatment with other medicines that cause respiratory depression; in infants and young children it is possible bronchial hypersecretion.

Sezolep drug interactions

Simultaneous administration of Sezolep with:

  • drugs providing a depressing effect on the CNS, ethanol, ethanol containing drugs may increase the CNS depressant effects.
  • Sezolep enhances the action of muscle relaxants, with valproate sodium reducing sodium valproate and the provocation of seizures.
  • described the case to reduce the concentration of desipramine in plasma in 2 times and its increase after withdrawal of Sezolep.
  • carbamazepine which causes the induction of microsomal liver enzymes may increase metabolism and the resulting decrease in concentration of Sezolep in plasma.
  • caffeine may reduce sedative and anxiolytic effects of Sezolep, with lamotrigine - may decrease the concentration of Sezolep in plasma, with lithium carbonate - the development of neurotoxicity.
  • primidone increases its concentration in blood plasma, with tiapride - possibly the development of NMS.
  • toremifene it is possible significant reduction in AUC and T1/2 of toremifene in connection with the induction of liver enzymes under the influence of Sezolep which leads to faster metabolism of toremifene.
  • may increase the concentration of phenytoin in blood plasma and the development of toxic reactions, its reduction or absence of these changes.
  • cimetidine increases the side effects of the CNS, however, the frequency of seizures in some patients decreased. There was described a case of headache with localization in the occipital region, while the application with phenelzine.

    Sezolep in case of emergency / overdose

    Symptoms: CNS depression of varying severity (from lethargy to coma): severe drowsiness, prolonged confusion, depression of reflexes, coma, possible respiratory depression.

    Treatment: induction of vomiting and the prescription of activated charcoal (if the patient is conscious), gastric lavage through a tube (if patient is unconscious), symptomatic therapy, monitoring of vital functions (breathing, pulse, blood pressure), in intravenous fluids (to increase urine output), if necessary, mechanical ventilation. As a specific antidote may be used benzodiazepine receptor antagonist flumazenil (in hospital), however, flumazenil is not indicated for use in patients with epilepsy (likely provocation of epileptic seizures).
