Nonsteroidal antiinflammatory drugs (NSAIDs) 37 of 72 Final Report Update 4 Drug Effectiveness Review Project Table 6. Strength of evidence by key question Key Question Strength of evidence Conclusion 1. Are there differences in effectiveness between NSAIDs, with or without antiulcer medication, when used in adults with chronic pain from osteoarthritis, rheumatoid arthritis, soft-tissue pain, back pain, or ankylosing spondylitis? Evidence is available from No clear differences in pain reduction. Indirect evidence from Both topical drugs had significantly greater mean topical solution and placebo-controlled trials. Are there clinically important differences in short-term (< 6 months) or long-term (≥ 6 months) harms between NSAIDs, with or without antiulcer medication, when used in adults with chronic pain from osteoarthritis, rheumatoid arthritis, soft-tissue pain, back pain, or ankylosing spondylitis? Evidence from many GI Harms: Lower risk for celecoxib than published trials and systematic nonselective NSAIDs in the short-term, but longer- reviews term evidence is inconclusive. CV Harms: No significant difference in risk of MI for celecoxib compared with nonselective NSAIDs, but evidence is primarily from short-term studies. Other serious adverse events: No consistent differences. Meloxicam Moderate for GI harms; low for Short-term and long-term GI harms: No consistent others differences. Long-term CV harms: No conclusive evidence of increased risk relative to nonselectives. Hepatotoxicity: No evidence of increased risk relative to placebo. Nabumetone Moderate for short-term GI Short-term GI harms: Decreased risk relative to safety; low for others nonselectives. Nonsteroidal antiinflammatory drugs (NSAIDs) 38 of 72 Final Report Update 4 Drug Effectiveness Review Project Key Question Strength of evidence Conclusion Other serious adverse events: No evidence. Etodolac Low for perforation, symptomatic Perforation, symptomatic ulcer, or bleeding rates ulcer, or bleeding, insufficient for (duration unknown): No increased risk relative to others nonuse. Nonselectives High for GI safety; moderate for Short-term/long-term GI safety: All nonselectives CV safety; low for other serious are associated with similar increased risks relative adverse events to nonuse. Short-term/long-term CV safety: Nonselective NSAIDs other than naproxen are associated with increased risks of CV events similar to that seen with COX-2 inhibitors (most data on high-dose ibuprofen and diclofenac). Naproxen appears to be risk-neutral with regard to cardiovascular events. Hepatotoxicity: In short-term trials, diclofenac associated with highest rates of aminotransferase elevations >3 times upper limits of normal. Noncomparative evidence suggests similar rates in the longer term. Fracture risk: Preliminary evidence from 1 case- control study suggestive of higher risk with ibuprofen compared with other nonselective NSAIDs. All-cause mortality/blood pressure/ CHF/edema/renal function/hepatotoxicity: No consistent difference. Nonselective+antiulcer Low for GI events; moderate for Clinical GI events: Misoprostol only antiulcer medications endoscopic ulcers medication proven to reduce rates, but at expense of reduced GI tolerability. Salsalate Low for short-term overall Short-term overall toxicity: Significantly lower toxicity and long-term GI harms, rates. Tenoxicam Insufficient No evidence found for specific GI and CV adverse events; reporting of AEs and dropouts slightly lower with tenoxicam compared with indomethacin and piroxicam respectively. Tiaprofenic acid Moderate for cystitis, insufficient Observational studies report serious cases of for others cystitis. Indirect evidence from Withdrawals due to adverse events: Significantly topical solution and placebo-controlled trials.
