Comparative StudySubeffective doses of nitroparacetamol (NCX-701) enhance the antinociceptive activity of the α₂-adrenoceptor agonist medetomidine.
The α₂-adrenergic system is involved in pain processing and inflammation-induced sensitization. α₂-adrenoceptor agonists induce analgesia, and this effect is greater when administered in combination with other analgesics. In the present study, we assessed a possible enhancement of antinociception combining the α₂-adrenoceptor agonist medetomidine with subeffective doses of NCX701 (nitroparacetamol). ⋯ In addition, the duration of antinociception was significantly longer (P<0.001, 100 min after administration). The use of low doses of NCX701 and α₂-adrenoceptor agonists might open new perspectives in the treatment of inflammatory pain.

Randomized Controlled Trial Multicenter StudyTransdermal buprenorphine plus oral paracetamol vs an oral codeine-paracetamol combination for osteoarthritis of hip and/or knee: a randomised trial.
Low-dose transdermal opioids offer a new therapeutic option for osteoarthritis (OA). This study compared symptom relief obtained with buprenorphine patches plus oral paracetamol with that obtained with an oral codeine-paracetamol combination tablet (co-codamol) in older adults with OA. ⋯ 7-day buprenorphine patches plus oral paracetamol were non-inferior to co-codamol tablets with respect to analgesic efficacy in older adults with OA pain in the hip/knee.

ReviewNSAIDs vs acetaminophen in knee and hip osteoarthritis: a systematic review regarding heterogeneity influencing the outcomes.
To identify sources of heterogeneity (statistical, methodological, and clinical) in studies evaluating non-steroidal anti-inflammatory drugs (NSAIDs) vs acetaminophen in patients with knee and hip osteoarthritis (OA) to elucidate variations in outcomes. ⋯ Future trials should present the results of hip and knee OA separately, as moderate clinical heterogeneity was found. There might be differences in effectiveness of NSAIDs vs acetaminophen in patients with hip vs knee OA. No significant methodological and statistical heterogeneity was found in studies evaluating NSAIDs vs acetaminophen.
