USPTO Abstract
Oxycodone formulations are provided which produce substantially flat in vivo steady state plasma profiles. Tolerance levels associated with such profiles and tolerance levels associated with biphasic profiles are shown not to be statistically different. The substantially flat in vivo steady state plasma profiles are produced by dosage forms having substantially zero order in vitro release profiles. Such release profiles produce low single dose in vivo Cmax levels which can reduce the probability of adverse side effects.
