OBJECTIVE To investigate the efficacy and safety of a bilayer combination oxycodone (OC) and acetaminophen (APAP) analgesic with both immediate-release and extended-release (ER) components (OC/APAP ER) in patients with moderate to severe pain using an established acute pain model. RESEARCH DESIGN AND METHODS This was a randomized, double-blind,(More)
BACKGROUND Prescription opioids have substantial abuse potential. This study compared the positive subjective drug effects of a newly developed extended-release (ER) oxycodone (OC)/acetaminophen (acetyl-para-aminophenol [APAP]) formulation with those of immediate-release (IR) OC/APAP. METHODS This randomized, double-blind, active- and placebo-controlled,(More)
OBJECTIVE To investigate the safety and satisfaction of patients treated ≤ 14 days after unilateral bunionectomy with extended-release oxycodone/acetaminophen (ER OC/APAP), a biphasic (ER and immediate release) fixed-dose combination analgesic being developed for moderate to severe acute pain. RESEARCH DESIGN AND METHODS This was an open-label extension(More)
A set of simple, rapid filtration methods has been developed for recovering enteroviruses from foods. The methods employ quite inexpensive equipment, and the resulting extract might be concentrated in any of several ways. Three model enteroviruses were apparently recovered with at least 80% efficiency when inoculated, at levels ranging from thousands to one(More)
Biphasic immediate-release (IR)/extended-release (ER) hydrocodone bitartrate (HB)/acetaminophen (APAP) 7.5/325-mg tablets are formulated with gastroretentive ER drug delivery technology that has been associated with clinically meaningful food effects in other approved products. Two phase 1 studies evaluated potential effects of food on single-dose(More)
