Metabolic disposition of pyrazinamide in the rat: identification of a novel in vivo metabolite common to both rat and human.
Only limited studies have been reported on the disposition and pharmacokinetics of pyrazinamide (PZA) in both animals and humans. The metabolism of PZA has never been completely elucidated,Expand
"Designer" amphetamines: effects on behavior and monoamines with or without reserpine and/or alpha-methyl-para-tyrosine pretreatment.
Rats were given single injections of vehicle or one of three doses of (+)-amphetamine (AM), 4-methoxyamphetamine (MA) or 4-ethoxyamphetamine (EA) after pretreatment with vehicle or reserpine, andExpand
New street analogs of phencyclidine
Abstract In the Summer of 1989 two new street analogs of phencyclidine (PCP) appeared in Canada. Analysis showed these to possess a benzyl and 4-methylphenyl moiety, respectively in place of theExpand
Stability of methadone in four vehicles for oral administration.
The stability of methadone in vehicles commonly used for oral administration was determined. Solutions of methadone were prepared in (1) orange-flavored Tang, (2) grape-flavored Kool-Aid, (3) appleExpand
High-speed liquid chromatographic separation of equine estrogens.
High-performance liquid chromatographic analysis of testosterone esters in oily solution.
High-performance liquid chromatography was used to analyze testosterone esters in oily solution. The procedure was based on a microparticulate silica column, with a chemically bonded hydrocarbonExpand
