HPLC QUANTIFICATION OF ZOLPIDEM AND PROTHIPENDYL IN A VOLUNTARY INTOXICATION

Zolpidem, a recently developed sleep inducer, and prothipendyl, a neuroleptic azaphenothiazine, were involved in a voluntary intoxication along with ethanol. After administration of flumazenil, a specific benzodiazepines antagonist, respiratory depression was corrected. HPLC with UV detection methods after selective extraction were developed to measure simultaneously prothipendyl and zolpidem without flumazenil interaction. These methods could be applied in drug monitoring and in emergency toxicology.
