The investigation is designed as an open-label, single dose, randomized, and cross-over study to determine the pharmacokinetics(PK) profile of oxycodone from OTR tablet 40 mg and OXYCONTIN tablet 40 mg in Chinese subjects with chronic pain in a fed stat.~Subjects with histories of chronic pain are chosen as the target population. Inclusion/exclusion criteria are strictly defined to reduce the potential variation of the PK data.
