Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Male or female patients who are 18 years of age or older
Patients who are scheduled for an elective cemented or uncemented total unilateral knee replacement or total unilateral hip replacement, under general or spinal anesthesia that does not include use of an intrathecal opioid
Post-surgical patients who have been admitted to the PACU and are expected to remain hospitalized and to have acute post-operative pain requiring parenteral opioids for at least 48 hours after surgery

Exclusion criteria

Patients who have undergone a replacement of the same knee or hip
Patients who have taken an opioid for more than 30 consecutive days, at a daily dose of more than 15 mg of morphine (or equivalent), within the past 3 months prior to surgery (e.g. more than 3 doses per day of Vicodin®, Norco®, Lortab® with 5 mg hydrocodone per tablet)
Patients with an allergy or hypersensitivity to opioids

Treatment and study plan

Sufentanil NanoTab PCA System/15 mcg

Drug

15 mcg Sufentanil NanoTab dosed sublingually every 20 minutes as needed for pain for at least 48 hours. Patients may elect to remain in study for up to 72 hours.

Other names: sufentanil sublingual microtablet system, Zalviso™

Placebo Sufentanil NanoTab PCA System

Drug

Placebo NanoTab dosed sublingually every 20 minutes as needed for pain for at least 48 hours. Patients may elect to remain in study for up to 72 hours.

Primary outcomes

Time-weighted Summed Pain Intensity Difference (SPID) Over the 48-hour Study Period (SPID48).

Time frame: 48 hours

SPID-48 is the sum of the pain intensity difference (PID) over the 48 hour time period. A pain intensity score of 0 (no pain) to 10 (worse possible pain) is obtained before starting the study and throughout the 48 time period. The pain score at each assessment time is subtracted from the baseline pain score to provide the total sum score or SPID-48. A higher SPID-48 is better and indicates a reduction in pain intensity compared to the baseline score. Range of SPID48 scores were -239 to 417.

Time-weighted SPID48 = ∑ [T(i) - T(i-1)] x PID(i), where T(0) = Time 0 (baseline), T(i) is the scheduled or unscheduled assessment time, and PID(i) is the PID score at time i for i=0 to 48 hours
