Pharmacological action

Lorazepam is an anxiolytic drug (tranquilizer), a derivative of benzodiazepine. This medication has anxiolytic, sedative, hypnotic, anticonvulsant, muscle relaxant central, antiemetic effect. The mechanism of the anxiolytic, sedative and hypnotic action is associated with increased inhibitory effect of GABA in the CNS. Anticonvulsant action, apparently in part due to increased presynaptic inhibition; inhibited the spread of epileptogenic activity arising in the epileptogenic foci in the cortex, thalamus and limbic structures, but not removed the excited state of the hearth. Muscle relaxant effect is primarily associated with the suppression of spinal polysynaptic afferent pathways and, presumably, an inhibition of monosynaptic afferent pathways; possibly also a direct inhibitory effect on motor nerves and muscle function.

Pharmacokinetics

After oral administration the bioavailability of Lorazepam is 95-99%. The plasma proteins binding is about 80%. Vd is 1.3 L / kg. Lorazepam is metabolized in the liver by conjugation to form inactive metabolites. T1/2 is 8-15 h. This medicine is derived primarily by the kidneys.

Lorazepam drug interactions

- drugs which have a depressing effect on the CNS, with alcohol, alcohol containing drugs increased inhibitory effect on the CNS.
- Lorazepam and alcohol may develop agitation, aggression, pathological intoxication (the development of this condition does not depend on the amount received ethanol).
- diminishes the effectiveness of oral contraceptives.
- enhanced effect of depolarizing relaxants.
- nicotine increases the metabolism of lorazepam, and decreases its activity.
- probenecid may interfere with the binding of lorazepam with glucuronic acid, resulting in higher concentrations in blood plasma, and by enhancing the therapeutic effect may develop excessive sedation.

Lorazepam in case of emergency / overdose

Symptoms: drowsiness, hypotension, confusion, depression of reflexes, coma.
Treatment: induction of vomiting, gastric lavage, IV introduction of norepinephrine to increase blood pressure, symptomatic therapy, monitoring of vital functions. The introduction of a specific antidote - an antagonist of benzodiazepine receptors flumazenil (in hospital).
