Randomized Controlled Trial Multicenter Study
Botulinum toxin type A in post-stroke upper limb spasticity.
To evaluate the efficacy and safety of one-time injections of botulinum toxin type A (BoNTA) in Japanese patients with post-stroke upper limb spasticity. ⋯ Higher-dose BoNTA reduced spasticity in upper limb muscles and improved ADL performance in terms of limb position and dressing. BoNTA is safe and effective in the treatment of post-stroke upper limb spasticity.

Randomized Controlled Trial Multicenter Study
Intranasal ketorolac for acute postoperative pain.
Efficacy and tolerability of intranasal ketorolac (SPRIX(R)) was assessed in abdominal surgery patients. ⋯ Intranasal ketorolac was well tolerated and provided effective pain relief within 20 minutes with reduced opioid analgesia use. While IN ketorolac was assessed in an inpatient, conventional surgery setting in this study, IN ketorolac use may have more relevance for use in outpatient settings and ambulatory surgery or fast-track surgical procedures.

Randomized Controlled Trial Multicenter Study
Efficacy and safety of a single-pill combination of amlodipine/valsartan in Asian hypertensive patients inadequately controlled with amlodipine monotherapy.
The antihypertensive efficacy of amlodipine/valsartan combination has not been evaluated in Asian patients as previous large-scale studies enrolled very few patients. This multicentre, randomised, double-blind study assessed the efficacy and safety of a single-pill combination of amlodipine/valsartan versus amlodipine in Asian hypertensive patients. ⋯ The single-pill combination of amlodipine/valsartan was efficacious and well-tolerated in Asian hypertensive patients who were inadequately controlled on amlodipine alone. As with all clinical trials, the entry criteria may limit the extrapolation of these results to a broader population. ClinicalTrials.gov Identifier: NCT00413049.

Randomized Controlled Trial Multicenter Study
Post-herpetic neuralgia: 5% lidocaine medicated plaster, pregabalin, or a combination of both? A randomized, open, clinical effectiveness study.
To compare efficacy and safety of 5% lidocaine medicated plaster with pregabalin in patients with post-herpetic neuralgia (PHN), and to assess the benefits of combining both drugs in patients not responding to either single agent. ⋯ Although this open-label study is lacking a placebo control group, the results suggest that 5% lidocaine medicated plaster is at least as effective as pregabalin for pain relief in PHN, with a favourable safety profile and a resulting positive benefit-risk ratio. In patients unresponsive to either monotherapy, combination therapy provides additional efficacy and is well-tolerated.

Multicenter Study
Innovative pain therapy with a fixed combination of prolonged-release oxycodone/naloxone: a large observational study under conditions of daily practice.
Chronic pain has a marked negative impact on quality of life. Opioid treatment is often effective in controlling this pain, but it has numerous side-effects, particularly affecting bowel function. ⋯ This is a multi-center, prospective, non-interventional, observational study. Analgesic efficacy and bowel function were assessed in patients suffering from long-lasting, severe chronic pain of different etiology (cancer and non-cancer) treated with combined PR oxycodone/PR naloxone and observed for 4 weeks. Pain was evaluated using the Brief Pain Inventory (BPI-SF) and constipation symptoms due to opioid treatment using the Bowel Function Index (BFI). Descriptive data are presented based on observed cases, efficacy and tolerability data additionally based on completely documented patients (for each parameter at least more than 2000 patients).
