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)
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)
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)
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)
To assess the feasibility and acceptability of a pharmacy-based clinical pharmacokinetic service for gentamicin, serum gentamicin levels were measured by radioimmunoassay in 44 patients hospitalized during a three-month period in an acute-care general hospital. Serum levels measured pre- and post-infusion were used to estimate pharmacokinetic parameters and(More)
Taurine status and pregnancy outcome were assessed in rats fed low dietary taurine and varying doses of guanidinoethyl sulfonate (GES), a structural analogue of taurine. Female Sprague-Dawley rats (225-270 g) were mated overnight and assigned to one of four groups from day 0 to 20 of gestation. Taurine-deficient animals were fed a basal diet containing <(More)
