The single-dose and steady-state pharmacokinetics and pharmacodynamics of oxycodone have been determined in patients with moderate to severe cancer pain. The mean +/- SD elimination half-life after single-dose administration of intravenous (4.6 mg to 9.1 mg) and oral (9.1 mg) oxycodone was 3.01 +/- 1.37 hours and 3.51 +/- 1.43 hours, respectively. After(More)
The single-dose pharmacokinetics and pharmacodynamics of oxycodone administered by the intravenous and rectal routes were determined in 12 adult cancer patients with moderate to severe cancer pain (visual analog scale [VAS] score, approximately 5). Oxycodone was administered by the intravenous and rectal routes with open drug administration and a cross-over(More)
The antinociceptive activity of noroxycodone (NOR) was determined and its potency compared with that of oxycodone (OXY) and morphine (MOR) after intracerebroventricular (icv) administration to Sprague-Dawley rats. The antinociceptive potencies of OXY and NOR relative to MOR were 0.44 and 0.17, respectively. Administration of naloxone (55 nmol icv) abolished(More)
The pharmacokinetics of oxycodone have been determined after single-dose administration by the intravenous (4.6-7.3 mg), oral (tablets, 9.1 mg and syrup, 9.1 mg), and rectal (30 mg) routes, in 48 patients undergoing minor surgery. There were no significant differences in the mean elimination half-lives between the intravenous (5.45 +/- 1.43 h), oral tablets(More)
Protein binding of oxycodone and morphine in human serum was determined in vitro using ultrafiltration. Binding studies were also performed using both purified human serum albumin and human alpha 1-acid glycoprotein (AAG). Albumin was found to be the major binding protein for both oxycodone and morphine. The serum protein binding of both oxycodone and(More)
Venous plasma concentrations of bupivacaine were determined in eight cholecystectomy patients following multiple interpleural bolus instillations of bupivacaine 20 ml 0.5% with adrenaline (5 mg/l) administered at six- to eight-hour intervals. The mean steady-state peak plasma concentration was 2.3 mg/l (range 1.2-3.1 mg/l); however, in three of the eight(More)
Cerebral angiography is still suggested as a first line investigation for patients with putative transient ischaemic attacks (TIA) and it is considered by most surgeons as a necessary prelude to carotid endarterectomy. That conventional cerebral angiography involves risk is well known, although the magnitude of this risk is not. Prospective studies of(More)
Reports results of a two-part questionnaire survey of information technology (IT) managers at 21 major UK retail banks, some of whom are using intranets and some not, to determine the degree of acceptance of intranets in the UK banking sector and to reveal the extent, of and reasons for, the adoption of intranets in their back offices; to explore the(More)
