BACKGROUND Oral fluid (OF) testing is increasingly important for drug treatment, workplace, and drugged-driving programs. There is interest in predicting plasma or whole-blood concentrations from OF concentrations; however, the relationship between these matrices is incompletely characterized because of few controlled drug-administration studies. METHODS Ten male daily cannabis smokers receiv...
Bromocriptine (BCT) is a dopamine D2 receptor agonist used for the treatment of Parkinson's disease and hyperprolactinemic disorders. After oral administration, BCT is metabolized into mono- or dihydroxylated metabolites. To study how these metabolites influence parent drug pharmacodynamics, we administered BCT to rats intravenously (1 mg/kg i.v.) and orally (10 mg/kg p.o.) and measured the inh...
BACKGROUND The purpose of this study was to evaluate intestinal absorption, organ distribution, and urinary elimination of the rare sugar D-psicose, a 3-carbon stereoisomer of D-fructose that is currently being investigated and which has been found to be strongly effective against hyperglycemia and hyperlipidemia. METHODS This study was performed using radioactive D-psicose, which was synthes...
OBJECTIVE To clinically evaluate a new patented multimodal system (SAFERSleep) designed to reduce errors in the recording and administration of drugs in anaesthesia. DESIGN Prospective randomised open label clinical trial. SETTING Five designated operating theatres in a major tertiary referral hospital. PARTICIPANTS Eighty nine consenting anaesthetists managing 1075 cases in which there w...
a box-behnken design with three replicates was used for preparation and evaluation of eudragit vancomycin (vcm) nanoparticles prepared by double emulsion. the purpose of this work was to optimize vcm nanoparticles to improve the physicochemical properties. nanoparticles were formed by using w1/o/w2 double-emulsion solvent evaporation method using eudragit rs as a retardant material. full factor...
Microspheres (MS) of Ketorolac Tromethamine (KT) for oral delivery were prepared by complex coacervation (method-1) and simple coacervation (method-2) methods without the use of chemical crossâlinking agent (glutaraldehyde) to avoid the toxic reactions and other undesirable effects of the chemical cross-linking agents. Alternatively, ionotropic gelation was employed by using sodium-tripolyphosp...
BACKGROUND Methamphetamine (METH) and amphetamine (AMP) concentrations in 200 plasma and 590 oral fluid specimens were used to evaluate METH pharmacokinetics and pharmacodynamics after oral administration of sustained-release METH. METHODS Eight participants received four oral 10-mg S-(+)-METH hydrochloride sustained-release tablets within 7 days. Three weeks later, five participants received...
