NSAIDs for Bone Health
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how different non-steroidal anti-inflammatory drugs (NSAIDs) affect bones and muscles after exercise. The medications tested include Celecoxib (Celebrex), Flurbiprofen, and Ibuprofen, along with a placebo for comparison. The goal is to determine how a single dose of these drugs influences the body's bone and muscle processes post-workout. Individuals who exercise at least twice a week and are willing to adjust their supplement and medication use may be suitable for this study. As a Phase 1 trial, the research focuses on understanding how the treatment works in people.
Will I have to stop taking my current medications?
You will need to stop taking NSAIDs and similar medications during the study, except for those provided by the study team. The protocol does not specify about other medications, but you must stop using nutritional supplements, alcohol, and nicotine during each study period unless approved by the study team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
A previous study found that ibuprofen was generally well-tolerated, but it may cause stomach issues or allergic reactions in people sensitive to aspirin. Celecoxib has been linked to a higher risk of serious heart problems, such as heart attacks and strokes. It may also cause bleeding in the stomach or intestines, sometimes without warning signs. Flurbiprofen can be harmful if swallowed or if it contacts the skin, and it might also irritate the skin or eyes. Each of these medications is already approved for other uses, providing some evidence of safety, but side effects can still occur. Always consult a healthcare provider to weigh the risks and benefits.12345
Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments because they explore how different NSAIDs—like ibuprofen, celecoxib, and flurbiprofen—affect bone metabolism after exercise. Normally, NSAIDs are used to relieve pain and inflammation, but this trial aims to see if they also influence how bones respond to physical stress. Each NSAID might interact differently with bone tissues, offering insights into which one could potentially aid in faster recovery or improved bone health. This could lead to more personalized approaches in managing exercise-related bone stress, beyond just pain relief.
What evidence suggests that this trial's treatments could be effective for post-exercise bone and muscle metabolism?
This trial will compare the effects of ibuprofen, celecoxib, and flurbiprofen, each taken as a single dose before a plyometric exercise bout, with a placebo. Research has shown that taking ibuprofen before exercise doesn't significantly alleviate muscle soreness or enhance performance and might slow the body's natural healing process. Celecoxib, another treatment option in this trial, appears ineffective in reducing swelling or muscle damage after exercise. Flurbiprofen, also being tested, doesn't significantly impact soreness or recovery. Overall, studies suggest these medications might not effectively ease muscle issues after exercise.678910
