Timeline
Interventions
During the open-label, titration period, all participants were administered hydrocodone ER tablets at dosages of 15, 30, 45, 60, or 90 mg every 12 hours to identify a dosage deemed successful for managing their pain. Hydrocodone ER was taken by participants randomized to the hydrocodone ER treatment arm during the double-blind treatment period at the dose level identified during the titration period. Participants were instructed to take tablets with a glass of water on an empty stomach at least 1 hour before or 2 hours after eating.
Placebo matching the active drug dose identified during the titration period was taken by participants randomized to the placebo treatment arm during the double-blind treatment period. Participants were instructed to take intervention with a glass of water on an empty stomach at least 1 hour before or 2 hours after eating.
