Randomized Controlled TrialA new model for using quantitative urine testing as a diagnostic tool for oxycodone treatment and compliance.
We conducted a prospective, randomized, cross-sectional study to develop and validate a new model to predict oxycodone in urine that can be used to help evaluate whether patients are complying with their oxycodone dosing regimens. We studied 20 patients: eight black women, two white women, six black men, and four white men; ages 48 ± 10 years (mean ± SD); weight 97 ± 32 kg. Pain levels before treatment averaged 9.5 ± 0.9 out of 10. ⋯ One patient was 35% below the prediction; the other was 51% above. Our model accurately predicts oxycodone in urine (±10% for 90% of the patients). The model appears clinically useful for evaluating the results of a quantitative urine test, since it objectively discriminates between (1) a "normal" patient complying with their oxycodone dosing regimen, and (2) a patient who may require genetic testing to distinguish between unusual metabolism or abuse.

Challenges to pharmacological management in this patient group include treatment concordance, comorbidity, polypharmacy, and age-related physiological changes affecting pharmacokinetics. Paracetamol (acetaminophen) is generally recommended as a first-choice analgesic in osteoarthritis pain. Topical nonsteroidal anti-inflammatory drugs (NSAIDs) should be considered ahead of oral formulations, and prescribing NSAIDs for older people requires careful consideration. There are some data relating to opioid use for noncancer pain in older people.

ReviewTherapeutic options for the treatment of postherpetic neuralgia: a systematic review.
Postherpetic neuralgia (PHN) is a chronic and painful condition that may result in significant disturbances to normal activities and decreases in the quality of life for those affected. Despite the availability of several first- and second-line treatment options, many patients may experience refractory pain. The objectives of this review were to summarize evidence for Food and Drug Administration (FDA)-approved and off-label therapies for the treatment of PHN and to present gaps in the current literature for future research focus. ⋯ However, evidence regarding the comparative effectiveness of these treatment alternatives is lacking. In order to choose the optimal treatment, providers should consider issues related to efficacy, safety, and tolerability in conjunction with patient goals, preferences, and adherence issues. Evidence from randomized or observational studies that directly compare agents with each other should help to inform treatment choices.

Observational StudyTapentadol prolonged release for severe chronic pain: results of a noninterventional study involving general practitioners and internists.
This noninterventional, prospective study investigated the administration of tapentadol prolonged release (PR; the dosage form described in this article is commercially available in Germany as Palexia retard; Grünenthal GmbH, Aachen) for severe chronic pain in routine clinical practice over a 3-month period. Effectiveness analyses included data from 3134 patients; 1331 received World Health Organization (WHO) Step III pretreatment. A total of 97.8% of patients received long-term analgesic pretreatment (42.5% with strong opioids). ⋯ Significant decreases in pain-related impairment of daily activities and improvements in quality of life (descriptive P value ≤.001) were observed with tapentadol PR with good tolerability. Tapentadol PR was effective for various pain indications in patients previously receiving strong opioids (67.2% achieved clinically relevant pain relief). Tapentadol PR can be considered an alternative therapy to classical opioids for treatment of severe chronic pain.
