Tapentadol prolonged release for patients with multiple myeloma suffering from moderate-to-severe cancer pain due to bone disease.
Myeloma bone disease (MBD) is a devastating complication of multiple myeloma that leads to severe pain. ⋯ Tapentadol PR started in doses of 100 mg/day was effective and well tolerated in opioid-naïve MBD patients with moderate-to-severe pain. Tapentadol PR can be considered a first-choice opioid in cancer patients suffering from mixed pain with a neuropathic component.

Low-dose naloxone provides an abuse-deterrent effect to buprenorphine.
In developmental research, plasma buprenorphine concentrations comparable to a 2 mg buprenorphine-naloxone (BN) sublingual tablet have been achieved with a 0.75 mg dose of BN buccal film, a small, bioerodible polymer film for application to mucosal membranes. This was a randomized, double-blind, placebo-controlled, single-dose, four-period crossover study in opioid-dependent subjects with chronic pain receiving >100 mg oral morphine equivalents daily who experienced withdrawal following a naloxone challenge dose. The objective of the study was to determine if intravenous (IV) naloxone doses of 0.1 and 0.2 mg would produce a withdrawal response when coadministered with a 0.75 mg IV dose of buprenorphine. ⋯ By 15 minutes postdose, the mean change in Clinical Opioid Withdrawal Scale (COWS) score from predose was 3.0 for placebo, 6.9 for buprenorphine, 9.8 for BN 0.1 mg, and 12.4 for BN 0.2 mg. The mean COWS score with each active treatment was significantly greater than placebo (P<0.001), and the mean COWS score for each of the naloxone-containing treatments was significantly greater than for buprenorphine alone (P<0.001). Naloxone doses as low as 0.1 mg added an abuse-deterrent effect to a 0.75 mg IV dose of buprenorphine.

Grading the intensity of nondental orofacial pain: identification of cutoff points for mild, moderate, and severe pain.
When assessing pain in clinical practice, clinicians often label pain as mild, moderate, and severe. However, these categories are not distinctly defined, and are often used arbitrarily. Instruments for pain assessment use more sophisticated scales, such as a 0-10 numerical rating scale, and apart from pain intensity assess pain-related interference and disability. The aim of the study was to identify cutoff points for mild, moderate, and severe nondental orofacial pain using a numerical rating scale, a pain-related interference scale, and a disability measurement. ⋯ The cutoff points established in this study can discriminate in pain intensity categories reasonably well, and showed a significant difference in most of the outcome measures used.

Pregabalin for the treatment of postoperative pain: results from three controlled trials using different surgical models.
To evaluate the efficacy and safety of pregabalin (150 or 300 mg/d) as an adjunctive therapy for the treatment of postoperative pain. ⋯ There were no significant differences between pregabalin and placebo with respect to the primary pain intensity measure in each of the three clinical trials. These studies encompass a large dataset (1,233 patients in total), and their results should be considered when assessing pregabalin's effectiveness in postoperative pain. Further studies are required to determine the potential pain-reducing benefit of pregabalin in the postoperative setting.

Postoperative pain management with transdermal fentanyl after forefoot surgery: a randomized, placebo-controlled study.
Quality of life is decreased in patients with hallux valgus deformity, mainly because of pain. Significant improvement is usually achieved by surgery. However, postoperative pain can be moderate to severe for 2-3 days. The aim of the present study was to evaluate the use of transdermal fentanyl for postoperative pain management after forefoot surgery. ⋯ As a part of multimodal analgesia with ibuprofen and acetaminophen, a patch delivering fentanyl 12 μg/hour did not significantly decrease the consumption of rescue opioid or pain scores after forefoot surgery.
