SUMMARY ⋯ Pregabalin 300 mg/day as an add-on to transdermal buprenorphine 35 µg/h led to significant pain reduction and a significant reduction of interference with sleep quality in patients with chronic low back pain.

SUMMARY ⋯ In this observational study in normal clinical practice, transdermal buprenorphine provided effective pain relief and was generally well tolerated by patients with cancer pain. It also improved quality of life for patients and reduced caregiver burden. Considering the high number of study discontinuations (mainly due to nontreatment-related death and lost to follow-up), the results of this study need to be evaluated with caution.

SUMMARY An extended-release, multivesicular liposome-encapsulated form of the local anesthetic bupivacaine, DepoFoam(®) bupivacaine (proposed proprietary name EXPAREL™), is in development for use as part of a multimodal regimen for the treatment of postsurgical pain. Placebo- and active-controlled clinical trials in patients who have undergone either orthopedic or soft-tissue procedures indicate that a single local administration into the surgical site results in analgesic activity for up to 3-4 days and decreases the use of opioid rescue medication. The safety profile of DepoFoam bupivacaine appears to be similar to that of bupivacaine HCl, and adverse events are dose-related.
