ReviewCombination analgesia in 2005 - a rational approach: focus on paracetamol-tramadol.
A multimodal (or balanced) approach to anaesthesia is a familiar concept that offers important benefits in the management of both acute and chronic pain. Rational combinations of analgesic agents with different mechanisms of action can achieve improved efficacy and/or tolerability and safety compared with equianalgesic doses of the individual drugs. Combining different agents also enhances efficacy in complex pain states that involve multiple causes. ⋯ Comparative trials have shown that paracetamol plus tramadol has comparable efficacy to paracetamol plus codeine, but with reduced somnolence and constipation compared with the codeine combination. The paracetamol plus tramadol combination is also free of organ toxicity associated with selective and non-selective non-steroidal anti-inflammatory drugs. Hence, paracetamol plus tramadol offers an effective and well-tolerated alternative to anti-inflammatory drugs or other paracetamol plus weak opioid combinations.

Pain is a leading cause of morbidity worldwide, with published data showing its prevalence as high as 50% for chronic pain in the European population. This prevalence is likely to continue to rise, particularly in elderly people with comorbid conditions and complex aetiologies of pain. There is thus a rapidly growing demand for safe and effective pain management. ⋯ Fixed-dose combinations of paracetamol with weak opioids, such as codeine, dextropropoxyphene or tramadol are currently available. Paracetamol plus tramadol is an effective and safe multimodal analgesic regimen for the management of both acute and chronic moderate-to-severe pain. Re-evaluating the role of weak opioids, such as tramadol, and combinations in pain management may prove a valuable option for prescribers seeking alternatives to anti-inflammatory drugs.

Persistent pain represents a major quality-of-life burden for patients and a challenge for their physician. Chronic pain often arises from multiple tissue sources and involves multiple chemical mediators and pain transmission pathways. Successful long-term pain management requires analgesic regimens that can treat pains of multiple origin and type. ⋯ Rational combinations of analgesic drugs offer a viable approach to managing persistent pain that involves multiple sites or pathways. The combination of paracetamol plus tramadol brings together two well-known analgesics that have different but complementary mechanisms of analgesic action. Laboratory studies have demonstrated that these agents interact to produce synergistic analgesia with a desirable safety/efficacy profile.

ReviewUpdate on guidelines for the treatment of chronic musculoskeletal pain.
Chronic musculoskeletal pain is a major - and growing - burden on today's ageing populations. Professional organisations including the American College of Rheumatology (ACR), American Pain Society (APS) and European League Against Rheumatism (EULAR) have published treatment guidelines within the past 5 years to assist clinicians achieve effective pain management. Safety is a core concern in all these guidelines, especially for chronic conditions such as osteoarthritis that require long-term treatment. ⋯ There are as yet no updated official guidelines that incorporate these new data and regulatory advice. An international multidisciplinary panel, the Working Group on Pain Management, has generated new recommendations for the treatment of moderate-to-severe musculoskeletal pain. These guidelines, formulated in response to recent developments concerning COX-2 inhibitors and other NSAIDs, focus on paracetamol as the baseline drug for chronic pain management; when greater analgesia is desired, the addition of weak opioids is recommended based on a preferable GI and cardiovascular profile, compared with non-steroidal anti-inflammatory drugs.
