Background Sufentanil sublingual tablet system (SSTS) is a recently approved formulation for postoperative pain management that has become popular due to its pharmacokinetic properties such as good bioavailability, rapid attainment of equilibrium and elimination without any metabolites, along with its pharmacodynamic properties such as rapid onset and effective pain reduction. It is also relatively well tolerated by patients.

Objective This is a quantitative analysis of the efficacy and safety of SSTS in patients with moderate to severe postoperative pain.

Design This is a systematic review and meta-analysis. Databases such as Cochrane Library, MEDLINE and EMBASE were searched for eligible articles.

Settings Randomised controlled trials published after 2000 in English language and which assessed at least one of the outcome measures of interest with pain intensity difference between 12 hours and a maximum of 96 hours.

Participants Adults with moderate to severe postoperative pain and taking SSTS for pain management.

Methods Data were analysed using Review Manager (RevMan) V.5.3. Risk of bias (RoB) assessment was done using RoB-2 scale, and overall grading of evidence of each outcome was done using GRADEpro Guideline Development Tool.

Results Analysis of SSTS versus control indicates a statistically significant reduction in summed pain intensity difference at 12 hours (mean difference (MD)=−12.33 (95% CI −15.5 to −9.17), p<0.00001), summed pain intensity difference at 48 hours (MD=−43.57 (95% CI −58.65 to −28.48), p<0.00001), time-weighted total pain relief over 12 hours (MD=−4.77 (95% CI −6.28 to −3.27), p<0.00001) and pain intensity difference (MD=–0.73 (95% CI −1.00 to −0.46), p<0.00001) with SSTS, alongside high quality of evidence. Success of treatment as assessed by Patient Global Assessment (OR=4.01 (95% CI 2.74 to 5.89), p<0.00001) and Healthcare Professional Global Assessment (OR=4.46 (95% CI 3.03 to 6.56), p<0.00001) scoring at 72 hours was observed in a significantly high number of individuals using SSTS, with high quality of evidence. There was no difference in adverse events except for dizziness (RR=1.90, 95% CI 1.02 to 3.52). There was a significantly higher number of total adverse events in orthopaedic surgery in the SSTS group than in the comparator.

Conclusion SSTS is effective in postoperative pain management in patients with moderate to severe pain. It also has good tolerability and high patient satisfaction.
