Seduxen is a benzodiazepine derivative and is a safe tranquillizer with anxiolytic, anticonvulsant and central muscle relaxant actions. Intravenous Seduxen injection is widely used in obstetrics and control of status epilepticus.

Pharmacology

Diazepam attaches to the specific site on the GABA receptor and potentiates the effect of GABA, which acts by opening chloride ion channels into cells.

Diazepam is absorbed rapidly and completely after oral administration. Peak Plasma concentration reaches within 15-90 minutes. Mean plasma half-life is 30 hours. Plasma protein binding is 98-99%. Diazepam is metabolized in the liver with only traces of the unchanged drug excreted in urine. A very small proportion of the metabolites is excreted through the bile into the intestine and eliminated with the feces. After rectal administration in suppository form diazepam is significantly absorbed and peak concentration reaches within 1.5-2 hours.

Interaction

Concomitant intake with alcohol is not recommended. Sedation may be increased due to concomitant use of neuroleptics (antipsychotics), hypnotics, sedative antihistamines and CNS depressants e.g., general anesthetics, narcotic analgesics or antidepressants. Seduxen clearance is increased by concomitant administration of phonobarbitone and is decreased by administration of cimetidine. Omeprazole and isoniazide inhibit Seduxen metabolism.
