Fed Study of Oxycodone Hydrochloride 30 mg Tablets and Roxicodone™ 30 mg Tablets

The objective of this open-label, randomized, two-period crossover study was to compare the oral bioavailability of a Mallinckrodt test tablet formulation of oxycodone 30 mg to an equivalent oral dose of a commercially available oxycodone tablet (Roxicodone™ 30 mg, Roxane Laboratories, Inc.) in a test group of healthy subjects under fed conditions.
