Although the metabolism and pharmacokinetics of chloral hydrate (CH) have been studied in healthy adults, no comprehensive studies have been done in neonates and young infants. Major physiological differences between these groups could greatly affect drug disposition. In this study the patient population (22 patients) was divided into three groups according(More)
Chloral hydrate has been used clinically for over 100 years. There is significant paucity of information regarding chloral hydrate metabolism in neonates and infants. Chloral hydrate and its various metabolites were quantitated in 12 neonates and 2 infants at prescribed time intervals. The analysis of the data indicates accumulation of trichloroacetic acid(More)
Although the metabolism and pharmacokinetics of chloral hydrate (CH) have been reported, there have been no attempts to correlate CH or its metabolite, trichloroethanol (TCE) with the sedative or hypnotic effects. In order to determine whether plasma concentrations of CH or TCE reflect the sedative/hypnotic effects, a sedation/agitation scale was developed.(More)
Our objective was to investigate whether zinc interacts with taurine to influence the development of retinal structure and function. Virgin female Sprague-Dawley rats were bred overnight and assigned to one of four treatments in a 2 x 2 factorial design with two levels of zinc (50 micrograms/g through gestation and 50 micrograms/g after parturition; 15(More)
The study objective was to evaluate the retinal response to deficiencies of zinc and taurine present throughout the period of postnatal retinal development. At parturition, Sprague-Dawley dams were assigned to one of four treatments in a 2 × 2 factorial design with two levels of zinc (4.5 and 50 μg/g) and two levels of taurine (0 and 2 μmol/g).(More)
A pharmacokinetic and tissue residue study was conducted to assess the risks associated with human consumption of polar bears in arctic Canada that have been exposed to the immobilizing drug Telazol, a mixture of tiletamine hydrochloride and zolazepam hydrochloride. Twenty-two bears were remotely injected with about 10 mg/kg of Telazol. Following(More)
A 62 year old woman presented with a long history of obsessive-compulsive disorder, the symptoms of which were not adequately controlled by oral clomipramine. The patient was started on intravenous clomipramine. Drug levels of both clomipramine and its active metabolite desmethylclomipramine were measured. Symptoms were controlled during her hospital stay.(More)
A simple, rapid and sensitive electron-capture gas chromatographic method has been developed for the simultaneous determination of chloral hydrate, trichloroethanol and trichloroacetic acid in biological fluids. The described method is applicable to single-dose pharmacokinetic studies of chloral hydrate in the adult. The method also meets the important(More)
