Should nonsteroidal anti-inflammatory drugs (NSAIDs) be prescribed to the older adult?

The prevalence of chronic pain increases with age, exceeding 50% in individuals aged ≥65 years. Nonsteroidal anti-inflammatory drugs (NSAIDs) are a mainstay of chronic pain management but carry significant dose-related risks of cardiovascular, renal, haematological and other systemic adverse events (AEs). Older patients have an increased risk of these AEs and are more likely to take multiple medications that can potentially interact with NSAIDs. In particular, older patients are more likely to have cardiovascular disease and a natural age-related decline in renal function, increasing the risks of cardiovascular, haematological and renal AEs. Given these risks, recent guidelines for the management of chronic pain in the elderly recommend using NSAIDs rarely and only in carefully selected patients. NSAIDs currently available in the US fall into three categories: nonselective NSAIDs that act via inhibition of cyclo-oxygenase (COX)-1 and COX-2; celecoxib, a selective inhibitor of COX-2; and topical NSAIDs that inhibit both COX-1 and COX-2 but result in much less systemic NSAID exposure than oral formulations. Topical NSAIDs have demonstrated efficacy similar to oral NSAIDs, with an incidence of AEs similar to placebo; however, these agents are an option only in patients with localized pain in superficial joints. Safe pain management in older patients therefore requires cautious choice of selective and nonselective oral NSAIDs, topical NSAIDs or non-NSAID analgesics. This article discusses the risks and benefits of NSAID therapy, reviews its mechanism of action as the source of adverse effects and provides recommendations for maximizing NSAID safety, particularly in older patients. Articles cited in this review were identified via a search of PubMed (January 2005 to November 2009) and a manual search of reference lists from the articles identified in that search. Priority was given to articles discussing NSAID use in older populations, clinical trials of high quality, reports on NSAID safety and AEs, and treatment guidelines.

Non-opioid analgesia improves pain relief and decreases sedation after gastric bypass surgery.

PURPOSE: Several non-opioid drugs have been shown to provide analgesia during and after surgery. We compared sevoflurane anesthesia with fentanyl analgesia to sevoflurane and non-opioid drug treatment for gastric bypass surgery and recovery. METHODS: Thirty obese patients (body mass index > 50 kg.m(-2)) undergoing gastric bypass were randomized to receive sevoflurane anesthesia with either fentanyl or a non-opioid regimen including ketorolac, clonidine, lidocaine, ketamine, magnesium sulfate, and methylprednisolone. Morphine use by patient-controlled analgesia (PCA) pump and pain score measured by visual analogue scale were determined in the postanesthesia care unit (PACU) and for the first 16 hr after surgery. Sedation was evaluated in the PACU. Investigators assessing patient outcomes were blinded to the study group. RESULTS: Fentanyl treated patients were more sedated in the PACU compared to the non-opioid group. Non-opioid treated patients required 5.2 +/- 2.6 mg.hr(-1) morphine by PCA during their stay in the PACU while patients anesthetized with fentanyl used 7.8 +/- 3.3 mg.hr(-1) (P < 0.05). Fentanyl and non-opioid treated patients showed no difference in pain score one or 16 hr after surgery. CONCLUSION: Our results show that non-opioid analgesia produced pain relief and less sedation during recovery from gastric bypass surgery compared to fentanyl.
