A subcutaneously-implantable reservoir for the sustained release of nicotine is described. The device, dubbed INR for Implantable Nicotine Reservoir, is a small glass cup sealed with Silastic polymer. It releases 3.4 mg of nicotine per 24 hours. When implanted into moderately-sized female Sprague-Dawley rats it produces blood nicotine levels of 400-500(More)
A drug delivery system (DDS) consisting of a perforated microtube (polyimide, inside diameter = 1.8 mm, tube length = 20 mm, hole size = 0.15 mm) was characterized in vitro and in vivo for its usefulness for long-term release of hydrophilic drugs at a constant rate. Sodium fluorescein mixed with stearic acid was used as the model drug. The DDS was packed(More)
Pharmacokinetic parameters of ethynyl estradiol 3-sulfate (EE-3) and 17-sulfate (EE-17) were estimated. Each sulfate was administered orally and intravenously to five ovariectomized volunteer women. Blood samples were taken over a period of 24 h. Radioimmunoassay for free and sulfoconjugated ethynyl estradiol (EE) was performed. The analysis of the plasma(More)
Comparative studies were pursued to investigate the locomotor activity induced by phencyclidine hydrochloride in CD-1 male mice. Horizontal, vertical, and rotational activity counts were quantitated using an infrared beam animal activity monitor. Five doses (1.5, 2.5, 3.5, 5.0, and 10.0 mg/kg, i.p.) of phencyclidine were compared. At the 1.5 mg/kg dose, no(More)
