A Study to Assess the Bioequivalence of a New ULTRACET Extended Release (ER) Tablet With Respect to a Marketed ULTRACET ER Tablet Under Fasted Condition

Overview

The purpose of this study is to evaluate the bioequivalence of a newly developed ULTRACET extended-release (ER) tablet of tramadol hydrochloride and acetaminophen, to the current marketed ULTRACET ER tablet, in healthy participants under fasted condition.
