S-(+)-methamphetamine hydrochloride ("ice") is abused by smoking (inhaling the vapors of the material). Male human volunteers inhaled the drug from a pipe heated at 300 degrees-305 degrees C for an average inhaled dose of 21.8 +/- 0.3 (SE) mg. The same volunteers were given an intravenous injection of 15.5 mg of S-(+)-methamphetamine hydrochloride.(More)
BACKGROUND Soy isoflavones are potential cancer chemoprevention treatments. OBJECTIVE We conducted safety studies of purified unconjugated genistein, daidzein, and glycitein, and defined pharmacokinetic parameters for their absorption and metabolism. DESIGN Thirty healthy men ingested a single dose of 1 of 2 isoflavone preparations purified from soy.(More)
The disposition of radiolabeled cocaine in humans has been studied after three routes of administration: iv injection, nasal insufflation (ni, snorting), and smoke inhalation (si). Metabolism, followed by urinary excretion of metabolites, proved to be the major route of elimination in all cases. Hydrolytic products (benzoylecgonine, ecgonine methyl ester)(More)
3,4,4'-Trichlorocarbanilide (TCC), uniformly labeled with 14C in the monochloro ring, was administered to rats, rhesus monkeys, and humans. Radioactive materials in the plasma and urine of all three species and in the bile of rats and monkeys were separated by high performance liquid chromatography. The chromatography showed great similarity between the(More)
This study investigated alterations in the disposition and pharmacodynamics of methamphetamine HCl after daily administration. Six male paid volunteers familiar with the use of amphetamines participated. Each subject was administered 10 mg of methamphetamine HCl as a slow-release preparation (Desoxyn Gradumets) at 9 a.m. for 13 consecutive days (days 2-14(More)
BACKGROUND Portable instruments that measure the prothrombin time and automatically calculate the international normalized ratio (INR) with the use of a drop of whole blood have simplified the treatment of patients who are receiving warfarin therapy. The accuracy of these portable monitors has never been determined by comparing INR results with a criterion(More)
The pharmacokinetics of orally administered S-(+)-methamphetamine-d3 were investigated in human male volunteers before and after a 13-day course of a slow release form of S-methamphetamine hydrochloride. A one-compartment pharmacokinetic model incorporating a lag time fits the data best. The average elimination half-life was 10.1 hr (range of 6.4-15.1 hr).(More)
Despite the increasing popularity of crystalline methamphetamine ("ice") vapor inhalation, no investigations have reported drug plasma concentrations and effects. Under controlled laboratory conditions, six subjects were studied. Plasma concentrations of methamphetamine were determined, and subjective and cardiovascular effects were measured.(More)
[3H]-Phencyclidine (PCP) hydrochloride was given in intravenous (0.1 or 1 mg) or oral (1 mg) doses to male subjects. After 1 mg IV, drug and metabolites were recovered in urine (72.8 +/- 4.0% of dose), feces (4.7 +/- 0.9%), and perspiration. Fecal excretion was low (3.4 +/- 0.4%) after oral dosing and oral bioavailability was estimated at 72%. PCP comprised(More)
